Thermal compound rests between the CPU (heatspreader) and the heatsink, and is used to improve heat conductivity in areas where the two metal surfaces aren't completely flush.
It is called Thermal Compound.
To improve the thermal bond between the chip and the heatsink. if the surface of the chip is uneven and the surface of the heatsink is also uneven then you wouldn't get anything close to 100% surface contact between them. To remove the gaps you use a compound that has a good thermal (heat) conductivity to fill in the gaps between the two objects.
If you're just changing the fan, no. If you're changing the entire heatsink, yes.
Thermal heat compound, also known as thermal paste or thermal grease, is typically made of a mixture of silicone, metal oxides, and/or carbon-based compounds. Its main role is to improve the thermal conductivity between a heat source (such as a CPU) and a heatsink, allowing for better heat dissipation.
Thermal compound is used to improve the thermal conductivity between a CPU or GPU and its heatsink, helping to transfer heat more efficiently and reduce temperature. It fills in microscopic gaps and imperfections on the surfaces, allowing for better heat dissipation. Using thermal compound helps prevent overheating and improves the overall performance and lifespan of the processor.
Well if you just want to clean off the dust you can you compressed air, but if you want to clean off the thermal compound then use rubbing alcohol or acetone.
Arctic Silver 5 High-Density Poly-synthetic Silver Thermal Compound Thermal paste, is commonly rated as the best. It's cheap and works great.
The recommended operating temperature range for Stars Thermal Grease Heatsink Compound ST360, manufactured by Shenzhen Tdtech Electronics, is typically between -50°C to 200°C. This range ensures optimal performance and thermal conductivity for various electronic applications. Always refer to the product's technical datasheet for specific details and guidelines.
Usually no, unless the box also comes with a heatsink. The paste will be on the bottom of the heatsink, not on the top of the processor.
The thermal paste is typically applied between the CPU and the heatsink, or the GPU and the heatsink, to fill in microscopic gaps and ensure better heat transfer between the two surfaces.
To apply thermal compound when reseating a CPU, place a small pea-sized amount at the center of the CPU. Avoid spreading it with your finger; instead, let the pressure from the heatsink spread it evenly when you install it. This method helps prevent air bubbles and ensures proper heat transfer.
Improper application of thermal compound can lead to poor heat transfer between the CPU and the heatsink, resulting in higher operating temperatures. This can potentially cause the CPU to overheat, leading to decreased performance, hardware damage, and system instability.
