What is the purpose of thermal paste compound between the CPU and heatsink?
Thermal compound, also known as thermal paste and thermal grease, is a material used to fill the microscopic gaps between a computer’s CPU and its heat sink. Thermal compound significantly increases the heat sink’s ability to cool the CPU, allowing the CPU to run at a higher speed and improve system performance.
What is thermal compound used for?
Thermal Paste – A silvery-gray substance that you apply to a processor before installing a cooling solution. It allows for an efficient transfer of heat from the IHS of the processor to the base plate or water block of the CPU cooler that is designed to dissipate that heat.
Is it OK to not use thermal paste?
Not using thermal paste between the CPU and the heat sink will cause it to eventually overheat and fail. This may not happen straight away but it will happen and in a much shorter time than if you use the thermal paste.
What happens if you don’t put thermal paste?
Without thermal paste, there is a small gap of air between some parts of the CPU and the cooler since both surfaces aren’t perfectly flat. This is especially true with any heatsink that has heat pipes that contact the CPU. The thermal paste is better than air at conducting heat.
What can be used as a heat sink compound?
Household substitutes for CPU thermal paste

- Yellow cheese 67.9°C.
What is the purpose of heat sink compound?
Heat sink compound (also called thermal grease, thermal compound, CPU grease, heat paste, heat sink paste, and thermal interface material) is a sticky paste that’s used as an interface between CPU heat sinks and heat sources. What is the purpose of heat sink compound?
Why do you use thermal paste on a heatsink?
By using thermal paste, you clog up the little gaps so that the seal between the heatsink and the processor is perfect. Thermal paste is specifically designed to conduct heat very well, so it acts at a much better heat transfer rate than air. This is why, when the paste gets old and less efficient,…
Can a thermal compound be used for heat transfer?
Since the grooves between the heatsink and the processor aren’t perfectly even, the thermal compound is perfect for use as a conduit to facilitate better heat transfer.
How are heat sinks used in thermal analysis?
A: The analysis begins with a thermal model of the component with which the heat sink is associated, usually an IC ( Figure 5). The model is used to trace the heat and dissipation from the IC active junction to the case, and then to the ambient environment.
