PC Cooling: The Importance of Keeping Your CPU Cool for PC Performance

Introduction

Did you know that modern CPU air coolers have liquid inside its copper tubes at near vacuum pressure? It boils at just 30 to 40 C. Modern gaming and workstation CPUs need these cooling solutions to process massive data while ensuring low temperatures. Keeping temperatures low is vital for system health. If we don't remove that heat quickly and stay within the operational limit, there are chances of permanent damage, thermal throttling, or malfunctioning.

As per Moore’s law, the number of transistors on chips doubles every two years. Historically, it's shown to increase the heat generation to move upward along with it. Engineers have developed advanced air based and CPU liquid coolers to deal with the demand. In this article, we will explore why we need to keep CPUs cooled and its impact on hardware performance.

Managing Heat from CPU

Excessive Heat and Performance

When the CPU reaches its peak operational temperatures, which are around 96 to 105 C, it starts to thermal throttle. It is an inherent feature of modern CPUs that allows them to reduce their operating frequency (processing speed) to protect themselves from damage. Studies have shown that superior cooling systems can achieve 15% better gaming performance during intensive sessions in comparison to standard cooling. Here are some impacts of heat on the CPU:

• Smoother Gameplay: Modern AAA games require lots of physics processing. All the load is sent to the CPU, which makes it heat up. With proper thermal management, the CPU performance remains unaffected, and the frame rates do not drop.
• Crashing: If the processor is unable to control the temperature, the system will eventually crash. It can also mean that some applications will start to lag or the system will shut down without any warning.

Hardware Longevity

CPU manufacturers know exactly when its life starts to degrade. The materials that make up a CPU are designed to take a virtually unlimited number of thermal cycles with temperatures below 80 C. When the temperature goes beyond 80, the temperature difference between normal room temperature and operating conditions becomes huge. The rapid thermal cycling causes damage to the material. Using a proper cooling system means:

• Lifespan Boost: Using a premium cooling system can increase the lifespan of a high end, intense work CPU by approximately 5 years. It is in comparison to the same CPU used with substandard or basic/stock cooling fans.
• Component Damage: If the CPU overheats, the motherboards on which the CPU is mounted can start to critically fail. The soldering and VRM (Voltage Regulator Module) can get damaged.

Working Mechanism of CPU Cooling Solutions

CPU Air Coolers

To fully grasp the importance of CPU coolers, it's valuable to understand their working mechanism. The easier to understand type is the air based PC cooling. The most basic version uses heat sinks that pull heat from the processor and transfer it to the surrounding air.

Modern advanced CPU air cooler versions use heat pipes that improve thermal performance by 20% as compared to basic ones. It uses liquid enclosed within these hollow pipes at low pressure. The liquid comes in touch with the CPU surface and evaporates, taking heat. Then moves to the heat sink (fins), cools down to liquid, and comes back to the CPU to take in heat again. Modern air coolers come with a variety of features, which include:

• Smart Fan: Using pulse width modulation (PWM), they allow computers to slow and speed up the fan speed as per requirement. It balanced the noise level with the cooling performance.
• Quieter Blades: With premium grade material and optimized fan blade designs, they reduce the noise level significantly. A typical high performance air based PC cooling solution will produce <35 dB(A) of noise.
• Surface Area: A larger surface area means more heat transfer. CPU air cooler manufacturers use the FIN process to increase the surface area of aluminum fins. It increases the extraction of heat from the copper heat pipes.

CPU Liquid Coolers

Liquid has a thermal capacity much higher than air. It can roughly hold 3000 times more heat by volume. Which means the system can be much more compact and offer more heat transfer capabilities. The working mechanism of CPU liquid coolers depends on three major components: the pump, the radiator, and the baseplate. To move the liquid between the heat source (base plate) and the heat sink (radiator), the pump is used.

Modern pre built all in one (AIO) liquid coolers offer the best performance. There are reduced chances of leakage, and they are ideal for DIY projects. Typically, these pumps push 1.2 L/min of fluid to keep the temperatures steady. Here are their key features:

• Radiators: They use large heat exchanger blocks called radiators. Their S shaped fins increase the surface area for heat dissipation. A fan blows cool air over these blocks to cool the tubes carrying the liquid.
• Micro Channel Plates: The baseplate touches the CPU's integrated heat spreader (IHS). The heat transfers to the baseplate and spreads across its inside, where microchannels are formed. These come in contact with the pumped liquid to transfer heat to the radiator via tubes.
• Silent Operation: As they have a large heat exchange capacity, the fans run at low RPM. Thus, it produces a lower noise level at the same CPU load as an air cooler.

Maximizing Hardware Potential

Overclocking and Heat Dissipation

Modern PC cooling solutions are more than just normal operation. They try to take PC performance past its limits. The manufacturer intentionally provides overclocking features in their CPUs. It allows the CPU to go beyond its normal operating speed. As the CPU goes past its normal speed, it starts to ramp up heat production exponentially. The internal resistance of the circuits starts to rise, and you need more electrical power (voltage) to keep it running.

If the power is supplied, the whole load comes to the CPU cooler to maintain its temperature for stable operation. Modern gaming CPUs have TDP mentioned as specifications. The CPU cooler needs to have a higher number in comparison to the TDP of the CPU. Here are some sample TDPs of modern CPUs:

• AMD Ryzen 9 9950X3D2 (Dual Edition): 200W
• Intel Core Ultra 9 285K / 270K Plus: 250W
• AMD Ryzen Threadripper PRO 9995WX: 350W
• Intel Xeon W9 3495X: 350W

Aesthetics and Silent Operation

Alongside CPU cooling performance, users demand aesthetics and comfort from their devices. Making head turning builds is the latest trend in PC hardware. PC cooling solutions also feature these mesmerizing, customizable displays and ARGB synchronization to deliver the ultimate user experience. One of the trending features is the use of digital temperature displays on the heatsink. It gives a direct real time value of the temperature without any software or processing delay.
