For Streaming & Content Creation: Priority on Thread Count

If you stream on Twitch via OBS, edit 4K videos, or have 50 Chrome tabs open while gaming, your "Kitchen" is crowded.

The Hidden Problem: Why High Core Counts Cause Overheating

Here is the fine print that spec sheets don't tell you: 

Modern CPUs use "Thermal Velocity Boost." They will automatically run faster, but only if they are cool enough. If you buy a high-end i9 or Ryzen 9 but pair it with a weak cooler, the CPU will hit 90°C instantly and Thermal Throttle (slow down). You paid for a Ferrari, but you're driving it in traffic.

"24 Cores," "32 Threads"—CPU marketing is confusing. Do you really need a server-grade processor just to play Call of Duty? Or is a mid-range chip enough? In this guide, we strip away the jargon to explain the difference between Physical Cores and Logical Threads, and reveal the one hidden factor that actually determines your FPS: Cooling.



What is the Difference Between Cores and Threads? 

To understand your computer, imagine your CPU is a Restaurant Kitchen.







Physical Cores = The Chefs





A physical core is like a Chef. If you have 6 cores, you have 6 chefs. They can each handle a completely separate order independently.



Logical Threads = The Hands (Hyper-Threading)





Thanks to technology like Hyper-Threading (Intel) or SMT (AMD), each Chef can use both hands effectively. A thread isn't a new chef; it's just the ability to multitask better. It helps organize background tasks so the Chef never stops working.





Simple Rule: Cores do the heavy lifting (Gaming); Threads handle the background chaos (Discord, Chrome, Windows updates).



Single-Core vs. Multi-Core Performance: Gaming vs. Streaming

Should you prioritize frequency (speed) or core count? It depends entirely on how you use your PC.





(AMD RYZEN 7 9800X3D PROCESSOR REVIEW, Vmodtech)



For Pure Gaming: Priority on Single-Core Speed

Most modern games still rely heavily on one "Main Thread." They prefer Fast Cores over Many Cores.





The Sweet Spot: A high-speed 6-core or 8-core CPU is usually the perfect configuration for gaming.



The Reality: A 6-core chip running at 5.0GHz will often beat a 20-core chip running at 3.0GHz in pure FPS.



For Streaming & Content Creation: Priority on Thread Count

If you stream on Twitch via OBS, edit 4K videos, or have 50 Chrome tabs open while gaming, your "Kitchen" is crowded.





Here, extra cores and threads are vital. They handle the video encoding in the background so your game doesn't stutter.



The Hidden Problem: Why High Core Counts Cause Overheating

Here is the fine print that spec sheets don't tell you: High core counts generate massive heat.

Modern CPUs use "Thermal Velocity Boost." They will automatically run faster, but only if they are cool enough. If you buy a high-end i9 or Ryzen 9 but pair it with a weak cooler, the CPU will hit 90°C instantly and Thermal Throttle (slow down). You paid for a Ferrari, but you're driving it in traffic.

How to Prevent Thermal Throttling with darkFlash

Don't let heat waste your money. You must match your cooling solution to your core count:





6 Cores (i5 / Ryzen 5): A high-quality Air Cooler is sufficient.



8+ Cores (i7 / i9 / Ryzen 7/9): You are entering the "Heat Zone." We strongly recommend a 360mm AIO Liquid Cooler, like the darkFlash EXPLORE DE360 CPU Liquid Cooler.



Why Liquid Cooling? It absorbs the sudden heat spikes from multi-core workloads instantly, keeping your CPU boosting at max frequency for longer gaming sessions.

More cores ≠ More FPS. Discover the one hidden factor that actually controls your gaming performance.

Unlike a mechanical switch that only knows "On" or "Off," a Hall Effect sensor acts like a dimmer switch. It knows exactly how far the key is pressed at all times—whether it is at 0.1mm, 2.0mm, or bottomed out at 4.0mm.

This is the main reason FPS players are upgrading their gear. On a normal mechanical keyboard, once you press a key, you have to release it past a fixed "Reset Point" before you can press it again. This physical travel distance slows you down.

 changes the rules using the continuous data from the magnetic switch:

This allows for instant "Counter-Strafing" in games like 

. You can stop moving, shoot accurately, and move again faster than physically possible on a mechanical board.

Beyond Rapid Trigger, magnetic technology offers several distinct advantages over traditional mechanical builds.

Because magnetic switches don't have "Debounce Delay" (no physical bouncing), the signal is clean and instant. High-end magnetic keyboards can report to your PC 

. This reduces latency to near zero (0.125ms), ensuring your inputs register the exact micro-second you react.

Fully Adjustable Actuation (0.1mm - 4.0mm)

One of the coolest features is customizability. You don't need to swap out switches to change the feel.

Friction is the enemy of electronics. Since magnetic switches have no metal contacts striking each other, there is significantly less wear and tear. They stay smooth (linear) for years longer than traditional switches.

If you are a casual gamer who primarily types or plays single-player games, a traditional mechanical keyboard is still a fantastic choice. The tactile feedback is hard to beat.

However, if you play competitive shooters and feel like your movement is just a split-second behind your brain, your hardware might be the bottleneck. The precision of 

 technology offers a tangible competitive advantage that mechanical switches simply cannot physically match.

If you follow the competitive scenes of Valorant, CS2, or Apex Legends, you may have noticed a quiet revolution happening on the desks of top pros. The satisfying "click-clack" of traditional mechanical keyboards is being replaced. The new king of esports? Magnetic Switches.



In this guide, we break down the difference between Magnetic and Mechanical switches, briefly explain the science behind them, and why features like Rapid Trigger are considered almost "cheating" in FPS games.



The Old Guard: How Mechanical Switches Work

To understand why pros are switching, you first need to understand what they are switching from.

Traditional mechanical switches work on physical contact. When you press a key, a plastic stem moves down, pushing two metal leaves together to complete an electrical circuit.





(Mechanical Switch Keyboard, darkFlash GD108 )



The Limitation: "Debounce Delay"

Because metal leaves vibrate (bounce) when they hit each other, the keyboard firmware has to wait a few milliseconds to ensure the keypress is real and not just a vibration. This is called Debounce Delay.





Pros: Satisfying feel, huge variety of customization.



Cons: Physical wear and tear, slower response time due to debounce, fixed actuation points.



The New Challenger: Magnetic Switches

Magnetic switches eliminate physical contact entirely. Instead of metal leaves touching, each switch contains a tiny permanent magnet. This is where the magic happens. The keyboard doesn't wait for two pieces of metal to hit; it constantly "watches" the position of that magnet using a sensor on the circuit board.





(Magnetic Switch Keyboard, darkFlash EZ68)



The Science: It’s Called the "Hall Effect"

While gamers call them "Magnetic Switches," the technology driving them is actually based on the Hall Effect.



What is the Hall Effect?

Discovered by Edwin Hall in 1879, this principle states that when a magnet moves closer to a sensor, the magnetic field changes the voltage running through that sensor.



Why does this matter for gaming?

Unlike a mechanical switch that only knows "On" or "Off," a Hall Effect sensor acts like a dimmer switch. It knows exactly how far the key is pressed at all times—whether it is at 0.1mm, 2.0mm, or bottomed out at 4.0mm.

The "Cheat Code": Rapid Trigger Explained

This is the main reason FPS players are upgrading their gear. On a normal mechanical keyboard, once you press a key, you have to release it past a fixed "Reset Point" before you can press it again. This physical travel distance slows you down.

Rapid Trigger changes the rules using the continuous data from the magnetic switch:





The moment you lift your finger (even by 0.1mm), the sensor detects the magnetic field changing and instantly resets the key.



The moment you press down again, it activates.

In-Game Benefit

This allows for instant "Counter-Strafing" in games like Valorant. You can stop moving, shoot accurately, and move again faster than physically possible on a mechanical board.

3 Reasons Why Gamers Are Upgrading

Beyond Rapid Trigger, magnetic technology offers several distinct advantages over traditional mechanical builds.



True 8000Hz Polling Rate

Because magnetic switches don't have "Debounce Delay" (no physical bouncing), the signal is clean and instant. High-end magnetic keyboards can report to your PC 8,000 times per second (8000Hz). This reduces latency to near zero (0.125ms), ensuring your inputs register the exact micro-second you react.



Fully Adjustable Actuation (0.1mm - 4.0mm)

One of the coolest features is customizability. You don't need to swap out switches to change the feel.





For Gaming: Set WASD keys to a hair-trigger 0.1mm for instant movement.



For Typing: Set keys to 2.0mm to prevent accidental typos.



For Safety: Set your "Ultimate" ability key to 3.0mm so you never waste it by mistake.



Durability (100 Million+ Presses)

Friction is the enemy of electronics. Since magnetic switches have no metal contacts striking each other, there is significantly less wear and tear. They stay smooth (linear) for years longer than traditional switches.



Conclusion: Is It Time to Switch?

If you are a casual gamer who primarily types or plays single-player games, a traditional mechanical keyboard is still a fantastic choice. The tactile feedback is hard to beat.

However, if you play competitive shooters and feel like your movement is just a split-second behind your brain, your hardware might be the bottleneck. The precision of Magnetic Switches combined with Rapid Trigger technology offers a tangible competitive advantage that mechanical switches simply cannot physically match.





Ready to experience the speed difference? Look for keyboards equipped with the latest Magnetic Switch technology, like the darkFlash EZ68, and feel the difference in your next match.

Pros are trading traditional mechanical switches for magnetic switches to gain a competitive edge through near-instant response times and customizable precision.

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.

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.



Typical throttle temperatures





CPU: around 90°C and above



GPU: 80–90°C depending on the model

Fixes





Improve Case Airflow: If your case feels like an oven, your components can't breathe. Consider upgrading to a high-airflow case like the darkFlash DY460 which features louvered side panels designed to maximize cold air intake.



(darkFlash DY460 ATX PC Case, featuring louver side panel on PSU Chamber)







Upgrade Your Cooler: Stock coolers often struggle with modern gaming loads. Switching to a darkFlash AIO Liquid Cooler (like the DE360/240 or DO360/240 Liquid Cooler) can drop temps significantly and keep boost clocks stable.



(darkFlash DE360 Liquid CPU Cooler)







Check Your Fans: Ensure you have positive or neutral air pressure. Adding high-performance darkFlash RGB fans not only looks great but ensures heat is actively pushed out of the chassis.



(darkFlash INF34 Cooling Fan, pre-installed in DY460 PC Case)



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

Most sudden FPS drops are caused by Heat or Power. 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.
