How do you apply thermal paste?
Just apply a drop or two to the old material and let it sit for a minute while the cleaner breaks up the grease in the thermal paste. Then, wipe it clean with a lint-free cloth. A coffee filter makes a terrific, cheap lint-free cloth. Repeat the process until both the CPU and cooler are totally clean, and then move on.
You need physical contact to move heat efficiently from the CPU heatspreader to the heatsink. The role of thermal paste is to "fill in the gaps" and allow for better transfer of heat from the heatspreader to the heatsink. Things don't work as efficiently as they should. Your CPU's operating temperature will be higher.
- Thermal grease, also called thermal paste or thermal compound, is a substance used to promote better heat conduction between two surfaces and is commonly used between a microprocessor and a heatsink . The top surface of most microprocessors is not perfectly flat.
- Thermal grease and thermal paste are the same thing. So is thermal compound, thermal goop, thermal gunk, heat paste, that gooey stuff you put between your CPU and heat sink, hot ass gloop-a-doop for your CPU-pa-doop. The terms are used interchangeably, but the brands and types vary in composition and effectiveness.
- 2 Answers. Thermal pads should be replaced with thermal pads only or with specially designed viscous thermal paste. The reason is that normal thermal paste is not designed to fill big gaps so sooner or latter will flow out and leave a gap between the component and the heat sink.
