Computer Cooling: The Importance of Thermal Grease

As computer performance continues to improve, the heat generated by components such as processors (CPUs) and graphics processing units (GPUs) is also increasing significantly.

1. Function of Thermal Grease

Thermal Grease is a viscous material with high thermal conductivity, mainly used to fill the tiny gaps between computer CPUs, GPUs and other heating components and radiators. Since the surfaces of the heat sink and components are not completely smooth and have unevenness at the microscopic level, these gaps will be filled with air, and the thermal conductivity of air is extremely poor, which will greatly reduce the heat dissipation effect.

2. The importance of Thermal Grease in computers

a) Improve heat dissipation efficiency

b) Prevent overheating damage

c) Maintain system stability

3. How to choose the right Thermal Grease

a) Thermal conductivity

Thermal conductivity is an important indicator of Thermal Grease performance, usually expressed in W/m·K (W/m·Kelvin).

b) Viscosity and fluidity

A higher viscosity can ensure that the silicone grease adheres stably to the component surface for a long time, but it should not be too thick, otherwise it will affect the heat dissipation effect.

c) Durability

High-quality Thermal Grease can still maintain its thermal conductivity properties at high temperatures, prevent hardening or oxidation, and reduce the frequency of replacement.

4. How to use Thermal Grease correctly

Clean the surface: Use a lint-free cloth or special cleaner to clean the contact surfaces of the CPU, GPU and radiator to ensure that the surface is free of dust and residue.

Apply the right amount: No need to apply too much, just a thin, even coat.

Compact the radiator: When installing the radiator, make sure it is pressed evenly against the Thermal Grease so that the silicone grease can be squeezed into every gap to reduce the generation of bubbles.

Regular inspection and replacement: Over time, Thermal Grease may age or fail due to high temperatures, affecting cooling performance.

Whether it is for high-performance gaming computers, workstations, or ordinary home computers, Thermal Grease is a cooling material that cannot be ignored.
