Build Guides                                                    

Whether it is the massive RTX 5090 or the efficient 5070, modern GPU coolers have become incredibly dense. 

With power draws pushing limits, the traditional "Front-to-Back" airflow strategy from the 2020s is struggling to keep up. This has made 

 airflow the new standard for high-end builds. But is it just for aesthetics? In this guide, we explain why the RTX 50 series practically 

The Problem with Front Intake: The "90-Degree" Turn

In a standard tower case, fans are usually mounted on the front panel, pushing cool air horizontally.

This setup worked fine for older generations, but it creates a conflict for modern cards like the RTX 5080:

This means your GPU has to fight to "grab" the cool air as it passes by, forcing the airflow to make a sharp 90-degree turn. With the increased thickness of 50-series heatsinks, this turbulence creates dead zones, forcing fans to spin louder just to maintain boost clocks.

Why Direct Cooling Wins: The Physics of Bottom Intake

When you install fans at the bottom of the case, the physics change completely. Bottom fans pull cool air from the lowest point (the coolest air in the room) and push it 

For cards with high power density like the RTX 5090 (which can spike over 500W), this 

 method is superior. Benchmarks show that adding bottom intake fans can lower GPU Core temperatures by 3-5°C, and significantly reduce the critical Hotspot Temperature.

Panoramic Cases: The New Standard for 2025/2026

By now, "Panoramic" or "Dual Chamber" cases (like the 

) are the norm for gaming builds. Since these cases use glass front panels, 

This setup prevents heat pockets from forming around the massive backplates of modern GPUs, ensuring your system performs as good as it looks.

With bottom intake becoming essential, aesthetic standards have also risen. Nobody wants to look at the ugly back frame of a fan on the bottom of their case.

The Solution: darkFlash Reverse Blade Fans To maintain a clean look:

 on the bottom allows you to pull air in (Intake) while showing off the "Infinity Mirror" center and clean RGB blades, keeping your build showcase-ready.





If you have upgraded to the latest RTX 50-series (Blackwell) graphics cards, you know the reality: Performance comes with heat. Whether it is the massive RTX 5090 or the efficient 5070, modern GPU coolers have become incredibly dense. 

With power draws pushing limits, the traditional "Front-to-Back" airflow strategy from the 2020s is struggling to keep up. This has made Bottom Intake airflow the new standard for high-end builds. But is it just for aesthetics? In this guide, we explain why the RTX 50 series practically demands airflow from the floor.



The Problem with Front Intake: The "90-Degree" Turn

In a standard tower case, fans are usually mounted on the front panel, pushing cool air horizontally.

This setup worked fine for older generations, but it creates a conflict for modern cards like the RTX 5080:





The GPU's Flow: The massive GPU fans pull air vertically upwards.



The Case's Flow: Front fans push air horizontally.





(darkFlash DRX70 Mesh ATX PC Case, with mesh front and optional bottom fan mounts)



This means your GPU has to fight to "grab" the cool air as it passes by, forcing the airflow to make a sharp 90-degree turn. With the increased thickness of 50-series heatsinks, this turbulence creates dead zones, forcing fans to spin louder just to maintain boost clocks.



Why Direct Cooling Wins: The Physics of Bottom Intake

When you install fans at the bottom of the case, the physics change completely. Bottom fans pull cool air from the lowest point (the coolest air in the room) and push it vertically upwards.





Zero Resistance: This airflow direction aligns perfectly with your GPU fans.



Instant Access: Cool air travels directly into the GPU heatsink without passing through drive cages or cabling.





(darkFlash DY460 ATX PC Case)



For cards with high power density like the RTX 5090 (which can spike over 500W), this "Direct Airflow" method is superior. Benchmarks show that adding bottom intake fans can lower GPU Core temperatures by 3-5°C, and significantly reduce the critical Hotspot Temperature.



Panoramic Cases: The New Standard for 2025/2026

By now, "Panoramic" or "Dual Chamber" cases (like the darkFlash DY460 ATX PC Case) are the norm for gaming builds. Since these cases use glass front panels, bottom intake is mandatory.







This design relies on an optimized "Chimney Effect":





Bottom: Forces cold air directly into the GPU.



Side: Supplies fresh air to the CPU and VRMs.



Top: Exhausts all rising heat immediately.

This setup prevents heat pockets from forming around the massive backplates of modern GPUs, ensuring your system performs as good as it looks.



Reverse Blade Fans: Don't Ruin the Look

With bottom intake becoming essential, aesthetic standards have also risen. Nobody wants to look at the ugly back frame of a fan on the bottom of their case.

The Solution: darkFlash Reverse Blade Fans To maintain a clean look:





Normal Blade Fan: Pushes air away from the pretty side.



Reverse Blade Fan: Pulls air through the pretty side.





(Left: Standard bottom fans via Reddit / Right: darkFlash INF34 Reverse Fans)



Using darkFlash Reverse Fans on the bottom allows you to pull air in (Intake) while showing off the "Infinity Mirror" center and clean RGB blades, keeping your build showcase-ready.



Conclusion: Do You Need Bottom Fans?









For Mid-Range GPUs (RTX 5060 / 5060 Ti): Traditional airflow is sufficient, but bottom fans help with noise.



For High-End GPUs (RTX 5070 & Up): Bottom intake is highly recommended. The thermal density of these cards benefits hugely from direct air.



For Glass/Panoramic Cases: Bottom intake is mandatory.

Is your gaming PC starting to look like a dust magnet? Or worse, are you noticing your temperatures creeping up and your frame rates dipping after a few months of use? While many builders obsess over RGB lighting or cable management, there is an invisible physics battle happening inside your case that determines the health of your PC: 

 air pressure is the key to keeping your components cool and, more importantly, dust-free. Let’s see how this works in practice, using the 

The Basics: How Air Pressure Works in a PC

Think of your PC case as a room. You have fans pushing air in (Intake) and fans pulling air out (Exhaust). The relationship between these two forces creates pressure.

Optimized Positive Pressure (Recommended)

How to Set Up the Perfect "Positive Pressure" Build

To achieve the "Goldilocks" zone of high airflow and low dust, follow this simple strategy using your components.

Step 1: Maximize Intake with Filtered Air

. However, you must ensure the intake air comes from a filtered source.

(fully open ventilation layout, with magnetic filters on top and side panel)

The "Floating" Advantage: Why the FLOATRON F1 Wins

Most panoramic "fish tank" cases suffer from a common problem: they sit too low to the ground, choking the bottom fans.

. By elevating the chassis, it opens up a massive airway for the bottom fans to pull in fresh, cool air without restriction.

The Perfect Positive Pressure Configuration

To achieve the "Goldilocks" zone of high airflow and low dust, simply fill the fan slots on the FLOATRON F1. The case is engineered to naturally create positive pressure:

. This setup guarantees that cool air is always forcing its way 

 of the cracks, keeping dust away from your precious components.

Dust acts as an insulator, trapping heat inside heatsinks. Even with positive pressure, you should check your filters every 3-6 months. The 

’s filters catch the dust before it hits your hardware, making cleaning as simple as peeling off the filter and wiping it down.





Is your gaming PC starting to look like a dust magnet? Or worse, are you noticing your temperatures creeping up and your frame rates dipping after a few months of use? While many builders obsess over RGB lighting or cable management, there is an invisible physics battle happening inside your case that determines the health of your PC: Air Pressure. 



Understanding the difference between Positive and Negative air pressure is the key to keeping your components cool and, more importantly, dust-free. Let’s see how this works in practice, using the darkFlash FLOATRON F1 M-ATX PC Case as our reference case."



The Basics: How Air Pressure Works in a PC

Think of your PC case as a room. You have fans pushing air in (Intake) and fans pulling air out (Exhaust). The relationship between these two forces creates pressure.



Positive Air Pressure (The Goal)





The Setup: Total Intake CFM (Airflow in) > Total Exhaust CFM (Airflow out).



The Physics: You are forcing more air into the case than the exhaust fans can pull out. This causes the extra air to naturally push out of every tiny crack, gap, and unfiltered vent in your chassis.



The Result: Dust cannot enter through the gaps because air is constantly rushing out of them. As long as your intake fans have dust filters, the inside of your PC stays clean.







Negative Air Pressure (The Dust Magnet)





The Setup: Total Exhaust CFM > Total Intake CFM.



The Physics: Your fans are pumping air out faster than it can get in, creating a vacuum effect.



The Result: Air (and dust) is sucked in through every unfiltered crack, PCIe slots, side panel gaps, and unused ports. This turns your PC into a vacuum cleaner.







Optimized Positive Pressure (Recommended)





The Setup: Total Intake CFM slightly > Total Exhaust CFM.



The Physics: This creates a clear airflow path where fresh cool air is forced in, while dedicated exhaust fans actively remove the rising heat. It prevents the "heat soak" that can happen if you only use intake fans.



The Result: The best of both worlds. You maintain the dust-repelling benefits of positive pressure while ensuring your GPU and CPU heat is efficiently ejected from the chassis.







How to Set Up the Perfect "Positive Pressure" Build

To achieve the "Goldilocks" zone of high airflow and low dust, follow this simple strategy using your components.



Step 1: Maximize Intake with Filtered Air

You want more fans blowing in than blowing out. However, you must ensure the intake air comes from a filtered source.





The "Fish Tank" Solution: On panoramic cases like the darkFlash FLOATRON F1, the front panel is glass, which looks great but blocks front airflow.



The Fix: The FLOATRON F1 features fully open ventilation layout. These allow you to mount high-performance fans (like the darkFlash DM8 LINE) on the side and bottom to pull massive amounts of cold air in.



Pro Tip: Since the FLOATRON F1 comes with dust filters, these intakes will catch the dust before it hits your GPU.





(fully open ventilation layout, with magnetic filters on top and side panel)



Step 2: Choose the Right Fan for the Job

Not all fans are created equal.





For Radiators (Top Exhaust): You want fans that can push through resistance.



For Case Intake: You want durability. Since intake fans often fight against dust filters, we recommend Hydro Bearing fans. They offer a longer lifespan (~40,000+ hours) compared to standard sleeve bearings and are whisper-quiet.





(darkFlash DM8 LINE)



Step 3: The "Chimney" Configuration

Heat naturally rises. Work with physics, not against it.





Bottom: INTAKE (Cold air for the GPU).



Side: INTAKE (Fresh air for the Motherboard/CPU).



Top/Rear: EXHAUST (Pushing the hot air out).







The "Floating" Advantage: Why the FLOATRON F1 Wins

Most panoramic "fish tank" cases suffer from a common problem: they sit too low to the ground, choking the bottom fans.

The darkFlash FLOATRON F1 solves this with its signature Suspension Design (Floating Base). By elevating the chassis, it opens up a massive airway for the bottom fans to pull in fresh, cool air without restriction.



The Perfect Positive Pressure Configuration

To achieve the "Goldilocks" zone of high airflow and low dust, simply fill the fan slots on the FLOATRON F1. The case is engineered to naturally create positive pressure:





Intake (5 Fans):





Bottom: 3x Fans (The floating base allows maximum air intake directly to the GPU).



Side: 2x Fans (Pulling fresh air for the Motherboard and CPU).



Exhaust (4 Fans):





Top: 3x Fans (Radiator exhaust).



Rear: 1x Fan.

The Math: 5 Intake Fans > 4 Exhaust Fans. This setup guarantees that cool air is always forcing its way out of the cracks, keeping dust away from your precious components.







A Final Tip on Maintenance

Dust acts as an insulator, trapping heat inside heatsinks. Even with positive pressure, you should check your filters every 3-6 months. The FLOATRON F1’s filters catch the dust before it hits your hardware, making cleaning as simple as peeling off the filter and wiping it down.

Few things are more frustrating than watching your FPS suddenly dip while you are in the middle of a game. Your system seems fine, temps look normal, but the frame rate just drops out of nowhere. These unexpected FPS drops are extremely common, and there are several real reasons behind them.

High Temperatures Causing Thermal Throttling

The number-one cause of sudden FPS drops is excessive heat. When your CPU or GPU gets too hot, it automatically reduces its clock speed to protect itself, leading to instant performance loss.

, featuring louver side panel on PSU Chamber)

Running out of VRAM can cause instant FPS drops. When VRAM is full, the GPU is forced to offload data to system RAM, which is much slower.

Sometimes your game is not the problem. Windows or other apps may be taking CPU, GPU, or RAM in the background (e.g., Chrome tabs, Windows Update).

Power Supply Issues (Insufficient or Unstable Power)

This is an often overlooked cause. If your PSU cannot handle sudden power spikes (transients) from a modern GPU, your system may throttle or crash.

Insufficient RAM or Single-Channel Memory

Your FPS may drop if your system is running out of RAM or if it is running at low speed.

Modern games stream assets constantly. If you install games on a slow HDD, you will notice stuttering when moving to new areas.

Even the best hardware will throttle if it's choked by dust. Dust acts as an insulator, trapping heat inside heatsinks.

Conclusion: Stabilize Your Framerates with darkFlash

. While software tweaks can help, the ultimate fix is often ensuring your hardware has the environment it needs to perform. Whether you need better airflow, powerful liquid cooling, or a reliable power supply, 

darkFlash has the gear to keep your frames high and your temps low.

VRAM (Graphics Memory) Is Full

Running out of VRAM can cause instant FPS drops. When VRAM is full, the GPU is forced to offload data to system RAM, which is much slower.



Fixes





Lower texture quality in game settings.



Turn off demanding effects like Ray Tracing if your card struggles.



Pro Tip: A well-cooled GPU boosts higher and handles loads better. Ensure your case has bottom or front fans directing air straight to the GPU.





Background Programs Eating Resources

Sometimes your game is not the problem. Windows or other apps may be taking CPU, GPU, or RAM in the background (e.g., Chrome tabs, Windows Update).



Fixes





Use "Exclusive Fullscreen" mode in games.



Turn on Windows Game Mode.



Check Task Manager for sudden spikes.

Power Supply Issues (Insufficient or Unstable Power)

This is an often overlooked cause. If your PSU cannot handle sudden power spikes (transients) from a modern GPU, your system may throttle or crash.



Symptoms





Sharp FPS drops during explosions or intense scenes.



GPU usage fluctuating wildly.

Fixes





Ensure Stability: Never skimp on your power supply unit. A high-quality PSU provides stable voltage even during load spikes.



Upgrade Capacity: If you are running a high-end card (like an RTX 5080) on an old 600W unit, it's time to upgrade to a darkFlash High-Wattage PSU to ensure your system gets the clean power it needs.



(darkFlash PMT Power Supply, Cybenetics platinum certified)



Insufficient RAM or Single-Channel Memory

Your FPS may drop if your system is running out of RAM or if it is running at low speed.



Fixes





Enable XMP / EXPO in BIOS.



Ensure you are using dual-channel configurations (two sticks are better than one).





Slow Storage Causing Loading Stalls

Modern games stream assets constantly. If you install games on a slow HDD, you will notice stuttering when moving to new areas.



Fixes





Always install AAA games on an NVMe SSD.





Dust Buildup & Maintenance

Even the best hardware will throttle if it's choked by dust. Dust acts as an insulator, trapping heat inside heatsinks.



Fixes





Regular Cleaning: Clean your PC every 3-6 months.



Use Dust Filters: This is why most of darkFlash cases come equipped with easy-to-remove dust filters. They catch the dust before it hits your components, making cleaning as easy as peeling off the filter and wiping it down.





Conclusion: Stabilize Your Framerates with darkFlash

Just months after the noticeable surge in DDR4 prices, the PC industry is facing another wave — this time with DDR5. Once expected to stabilize as production matured, DDR5 memory is now climbing sharply in cost. 

From high-end desktop kits to mainstream 16 GB modules, prices have risen as much as 

 in certain regions. What’s driving this new round of increases — and how might it affect PC builders, system integrators, and component brands?

, DRAM spot prices surged nearly 10% in a single week this October as buyers rushed to secure inventory ahead of further hikes. DDR5 modules — which once benefited from falling prices as adoption spread — are now trending upward in both spot and contract markets.

 reports that community data shows retail DDR5 kits from brands like Corsair, G.Skill, and Kingston rising significantly in Europe and Asia. In some regions, the price per gigabyte has nearly doubled compared to mid-year 2024 levels.

For consumers, this means one clear thing: upgrading or building a DDR5-based system is getting more expensive again.

The reasons behind the DDR5 price rise are complex, but a few major factors stand out:

Global AI infrastructure build-outs are consuming vast amounts of memory. Data centers deploying GPUs like NVIDIA’s H100 and H200 rely on high-bandwidth DRAM (HBM) and advanced DDR5 chips, directly competing with consumer-grade production capacity.

 recently noted, “AI data centers are swallowing the world’s memory supply.” This diversion of wafer allocation from PC DRAM to HBM has reduced output for DDR5 modules used in consumer and enterprise PCs.

2. Manufacturers Prioritizing High-Margin Products

Major DRAM suppliers — Samsung, SK Hynix, and Micron — have strategically shifted focus toward more profitable segments like HBM3E and LPDDR5X. Commodity DDR5 modules yield lower profit per wafer, so manufacturers are scaling back consumer DRAM lines to optimize margins.

When rumors of supply shortages surface, memory module assemblers and distributors often buy ahead to lock in pricing. This behavior, while rational, amplifies short-term demand and constrains supply in the spot market, leading to sudden price spikes — the same pattern we saw during DDR4’s recent rebound.

4. Supply Chain Transition and Yield Issues

As fabs migrate to 1β and 1α nm nodes for next-gen DRAM production, yields can initially drop. That limits supply while costs remain high. Combined with continued geopolitical uncertainties and logistics challenges, memory output simply isn’t keeping up with demand.

For PC builders and DIY enthusiasts, higher DDR5 prices increase total build cost — especially in mid-range and performance segments.

A memory kit that cost $80–90 earlier this year may now exceed $120–130. While that might seem minor for premium builds, it directly affects the 

, driven by AI hardware demand and restrained production volumes. TrendForce predicts overall DRAM prices could rise 

The silver lining is that DDR5 remains in high demand thanks to platform adoption (Intel 700-series, AMD AM5). As more users transition, economies of scale could eventually bring stability — but not before this current shortage cycle plays out.

DDR5’s price surge highlights the new reality of a memory market dominated by AI and data-center demand. As production capacity shifts toward high-bandwidth applications, consumer DRAM will continue to feel the squeeze. For PC enthusiasts and brands alike, this isn’t just a supply-chain story — it’s a reminder that even as technology evolves, the economics of silicon remain as volatile as ever.





Just months after the noticeable surge in DDR4 prices, the PC industry is facing another wave — this time with DDR5. Once expected to stabilize as production matured, DDR5 memory is now climbing sharply in cost.

For PC builders and DIY enthusiasts, higher DDR5 prices increase total build cost — especially in mid-range and performance segments.

A memory kit that cost $80–90 earlier this year may now exceed $120–130. While that might seem minor for premium builds, it directly affects the bill of materials (BOM) for integrators and system assemblers.



Market Outlook





Analysts expect the DRAM price uptrend to continue into early 2026, driven by AI hardware demand and restrained production volumes. TrendForce predicts overall DRAM prices could rise 10–20% quarter-over-quarter, depending on market response.

The silver lining is that DDR5 remains in high demand thanks to platform adoption (Intel 700-series, AMD AM5). As more users transition, economies of scale could eventually bring stability — but not before this current shortage cycle plays out.



What Builders and Buyers Should Do





Secure modules early: If you’re planning new PC builds or system batches, lock in DDR5 inventory before the next quarter’s pricing revision.



Offer flexible configurations: For OEMs or boutique builders, consider offering both DDR4 and DDR5 SKUs where platform compatibility allows.



Monitor supplier communication: Stay updated with module vendors on lead times and allocation changes.



Communicate value: Even as costs rise, focus marketing on overall system performance, stability, and forward-compatibility, not just raw specs.



Conclusion

DDR5’s price surge highlights the new reality of a memory market dominated by AI and data-center demand. As production capacity shifts toward high-bandwidth applications, consumer DRAM will continue to feel the squeeze. For PC enthusiasts and brands alike, this isn’t just a supply-chain story — it’s a reminder that even as technology evolves, the economics of silicon remain as volatile as ever.

DDR5 memory prices are climbing sharply in 2025 as AI demand, supply reallocation, and panic buying tighten the DRAM market. Here’s why it’s happening and what it means for PC builders.

Step 2｜Power Down and Unplug

Since cleaning may involve removing panels or using cleaning solutions, always turn off your PC and disconnect the power cable to ensure safety and prevent component damage.



Step 3｜Gather Cleaning Tools

You’ll need:





A microfiber cloth, lens cloth, or screen-cleaning cloth



Neutral detergent (optional) and clean water



A dust blower or anti-static brush



How to Clean Your Glass Panel Properly





Step 1｜Remove Dust with a Dry Cloth

Use a clean microfiber cloth to gently wipe away surface dust.
Avoid using a damp cloth directly — trapped dust can scratch the glass surface.



Step 2｜Apply Cleaner to the Cloth (Not the Glass)

Spray the neutral cleaner onto the cloth instead of directly onto the glass to prevent streaks or residue from forming on the panel.



Step 3｜Wipe in One Direction

Gently wipe from top to bottom or left to right, following a single direction. Avoid back-and-forth rubbing, which can cause micro-scratches.



Step 4｜Detail the Corners

For tight corners or edges that collect dust, use a cotton swab or a small piece of cloth for spot cleaning.



Tip: Never use tissue or paper towels, they can scratch the surface or leave lint behind.



Preventing Scratches and Routine Maintenance





Clean Regularly

Wipe down your case every 3 to 6 months to prevent dust buildup that becomes harder to remove over time.



Minimize Panel Removal

Avoid removing the glass panel unless necessary. Frequent handling increases the risk of scratches or smudges.



Handle Panels Carefully

When removing the glass panel, avoid placing it face-down on any surface.
Keep it upright to reduce contact and the chance of scratches.







Conclusion

Proper glass maintenance not only keeps your PC case looking stunning but also enhances its overall professional appearance. By cleaning regularly and wiping correctly, you can prevent dust and scratches from stealing the spotlight from your carefully built masterpiece.
