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.

Your PC is running louder than usual, and your frame rates are dropping. You’ve cleaned the dust filters, checked your fans, but the temperatures are still creeping up. The culprit might be the most overlooked component in your build: 

Many users install their CPU cooler once and forget about it for years. However, thermal compound is not permanent. It degrades, dries out, and loses its effectiveness over time.

The Golden Rule: How Long Does Thermal Paste Actually Last?

There is no single expiration date for thermal paste, but there is a general consensus among hardware experts and manufacturers.

Cheaper silicon-based compounds tend to dry out ("cure") faster, leading to cracks and air gaps. Premium compounds often use higher-quality suspensions that stay liquid longer.

However, if you are a heavy user who pushes your PC to its limits (video editing, 4K gaming, AI rendering) daily, the heat cycles will degrade the paste faster than a PC used only for web browsing.

5 Signs Your PC Needs New Thermal Paste Immediately

Your PC will tell you when it’s suffering. If you notice any of these symptoms, it’s time to grab a tube of paste:

If your CPU sits at 50°C+ while doing nothing (and it used to be 35°C), the heat transfer is failing.

Are your fans ramping up to 100% speed just by opening a web browser? This suggests the cooler is struggling to pull heat away from the chip.

If your game suddenly lags or stutters after 30 minutes of play, your CPU/GPU might be slowing itself down to prevent damage.

Sudden shutdowns during intensive tasks are a major red flag.

If you remove your cooler for any reason, 

 replace the paste. Never reuse old paste.

CPU vs. GPU: Why Repasting a Graphics Card is Different

 is a standard maintenance task. It's low risk and easy to do.

In many regions, unscrewing your graphics card backplate may void the manufacturer's warranty.

GPUs often require dealing with delicate thermal pads for VRAM and VRMs in addition to the paste for the core.

Unlike CPUs, which have an Integrated Heat Spreader (IHS), GPU dies are exposed. One mistake in mounting pressure can crack the chip.

Repaste your CPU as regular maintenance. Only repaste your GPU if temperatures are critically high and the warranty has expired.

Why Does Thermal Paste Degrade? (The Pump-Out Effect)

Why doesn't it last forever? Two main reasons:

The solvents in the paste evaporate over time, turning the smooth liquid into a chalky, cracked solid that cannot transfer heat efficiently.

As your CPU/GPU heats up, it expands. When it cools down, it contracts. Over thousands of these heating/cooling cycles, the thermal paste is physically "pumped out" from the center of the chip towards the edges, leaving the hottest part of the processor with little coverage.

. Ideally, the radiator should be mounted higher than the pump so that any air collects in the radiator and doesn’t damage the pump.

Slowly tilt your PC case left and right to help dislodge air bubbles stuck in the tubing. This encourages the bubbles to move to the radiator, where they won’t interfere with the pump.

Use your cooler’s software to set the pump speed to 100% and let it run for 30–60 minutes. This increases fluid pressure in the loop and helps push out trapped air.

Step 4: Rotate the Case to Different Angles

If the bubbling noise persists, try rotating your case about 45 degrees in various directions. This can help release stubborn bubbles that haven’t yet settled.

⚠️ Pro Tip: Since these steps involve moving the PC, it’s a good idea to remove heavy components like the GPU and mechanical hard drives to avoid damage during handling.

What If the Bubbling Noise Doesn’t Stop?

If the noise continues even after these steps, your AIO cooler may have shipped with excess air or developed a leak. Contact the manufacturer’s support for further assistance or to request a replacement.

Custom Loop Liquid Cooling







What is a Custom Loop?

A custom loop liquid cooling system is an open-loop system that users build from individual components. Unlike AIO coolers, each part—such as the CPU block, reservoir, radiator, pump, tubing, and fittings—must be purchased and assembled separately.

Custom loops deliver top-tier cooling performance and maximum customization, but they are more complex to build, time-consuming, and costly to maintain.







Components of a Custom Loop

A typical custom loop includes the following:





CPU Block: Mounted on the CPU to absorb and transfer heat into the coolant.



Pump: Drives coolant through the entire loop.



Reservoir: Stores coolant, allows for easy monitoring of coolant levels, and helps with refilling and air removal.



Tubing: Carries coolant through the loop. Available in soft tubing and hard tubing options.



Coolant: Transfers heat and can be clear or colored for aesthetics.



Fittings: Connect tubing to components; ensure tight seals to prevent leaks.







Pros





Superior cooling performance: Can cool both CPU and GPU, ideal for heavy overclocking or workstation setups.



Highly customizable appearance: Use of hard tubing, distribution plates, colored coolant, and RGB lighting enables fully personalized aesthetics.



Scalability: Supports dual radiators, large reservoirs, multiple loops, and sensor integration.



Cons





High skill requirement: Requires knowledge of liquid cooling and hands-on assembly experience—not beginner-friendly.



Time-consuming installation: Can take hours or even days to complete; includes leak testing and air bleeding.



Expensive: Individual components can be costly—entire setups often cost hundreds of USD.



Higher risk: Improper installation can lead to coolant leaks and potential hardware damage.



Buying Recommendations

. While the fan and platform (Intel or AMD) also play a role, their impact on thermal performance is relatively minor in comparison.

Heat pipes are the backbone of any air cooler’s heat transfer system. The thicker and more numerous the heat pipes, the better the cooling performance.

more and thicker heat pipes = better heat dissipation

The baseplate is the interface between the CPU and the cooler, and it plays a significant role in how effectively heat is transferred. There are three main types of baseplates, ranked from highest to lowest thermal efficiency:

The flattened heat pipes directly contact the CPU surface, minimizing the thermal barrier.

A flat copper plate is used as the base, with heat pipes soldered directly into it for better contact and durability.

This design uses a sealed chamber filled with conductive liquid to evenly distribute heat across the baseplate.

Cooling fins are responsible for dissipating heat into the surrounding air. The more fins and the tighter their spacing, the more efficient the heat dispersion.

Fins are permanently soldered to the heat pipes, resulting in strong structural integrity and excellent heat transfer. Though costlier, it's more durable and effective.

Heat pipes are inserted through stacked metal fins, forming a tower structure. This method is more affordable but depends heavily on manufacturing quality. A precise fit ensures firm contact and better performance, while poor fitting can cause fins to loosen over time and degrade thermal efficiency.

While not as critical, a few additional factors can slightly affect air cooler performance:

Key #1: Heat Pipes

Heat pipes are the backbone of any air cooler’s heat transfer system. The thicker and more numerous the heat pipes, the better the cooling performance.





Pipe Thickness: Most air coolers on the market use 6mm heat pipes, though high-end models may include 8mm pipes for improved heat transfer.



Number of Heat Pipes: Entry-level air coolers typically feature 4 heat pipes, while flagship models often come with 6 or 7 for maximum efficiency.

The basic rule is: more and thicker heat pipes = better heat dissipation.

Top 3 Key Factors That Affect Air Cooler Performance

エアクーラーの性能に影響を与えるものは何でしょうか？購入前に重要な要素を知っておきましょう！

エアクーラーの性能に影響を与える3つの重要な要素

When your CPU is under heavy load, temperature spikes are inevitable. While traditional air coolers are budget-friendly, they often struggle to keep up with high-performance processors. That’s where liquid coolers come in — the go-to choice for gamers and power users alike.

But have you ever wondered what a liquid cooler actually is, and why it outperforms traditional air cooling systems?

A liquid cooler is a closed-loop system that circulates coolant to absorb and transfer heat away from the CPU. The coolant carries the heat to a radiator, where it's released into the air with the help of fans — all while maintaining high efficiency and low noise levels.

Liquid has a much higher thermal conductivity than air, allowing it to draw heat away from the CPU faster. This is especially beneficial for high-end CPUs or overclocked systems that generate a lot of heat.

Since liquid cooling is more efficient, fans don’t need to spin at high speeds to keep temperatures low. As a result, the system stays quieter during operation.

Liquid coolers often have a cleaner, more compact design compared to bulky air coolers. With modern additions like built-in screens on the water block and RGB fans, they add visual appeal and are perfect for gaming or showcase builds.

Liquid coolers can keep temperatures low even under extended high workloads, reducing the risk of thermal throttling and ensuring better system stability and performance over time.

Who Should Consider Getting a Liquid Cooler?

If you're running a top-tier processor, maintaining stable output and avoiding heat damage is key. A liquid cooler helps efficiently remove excess heat, keeping your CPU at safe operating temperatures.

Enthusiasts with Basic PC Hardware Knowledge

While liquid coolers offer powerful performance, they do come with a limited lifespan (typically 5 to 8 years due to the use of coolant). Once the warranty ends, it's recommended to replace the cooler — making it slightly more maintenance-intensive than air coolers.

Liquid coolers now come in all kinds of designs, from minimalist to flashy. Some even include customizable screens on the water block. They’ve evolved from simple cooling tools into centerpiece components of high-end custom PC builds.

What Is a Liquid Cooler?

A liquid cooler is a closed-loop system that circulates coolant to absorb and transfer heat away from the CPU. The coolant carries the heat to a radiator, where it's released into the air with the help of fans — all while maintaining high efficiency and low noise levels.







How Does a Liquid Cooler Work?





Water Block (CPU Block)
Mounted directly on the CPU, the water block has a thermal metal base that makes contact with the CPU and coolant. Thermal paste is applied to enhance heat transfer from the CPU to the block.



Pump
The pump keeps the coolant circulating through the system.



Radiator
The heated coolant flows into the radiator, where large surface-area fins dissipate the heat.



Fans
Attached to the radiator, fans help expel the hot air from the case quickly and efficiently.
