Why not just use the thermal paste that comes with a CPU?
While both AMD and Intel processors and motherboards can come with thermal paste, it’s a good idea to buy your own. Aftermarket paste has a tendency to spread heat better and has a better overall thermal conductivity than the stuff that comes packaged in with your components.
How much thermal paste should you use?
As a general rule, most people tend to go with about a pea-sized amount of thermal paste. Just be sure to spread it evenly over the surface of your processor so that the heat can be spread evenly and you’ll get nominal operational temperatures out of your processor.
When removing thermal paste, is there a chemical that can get rid of the old stuff?
For the most part, you can get away with just applying some WD-40 to the surface of your processor to remove the excess thermal paste. While acetone is an option, it can cause issues with plastic components on your motherboard. Additionally, there are other solutions to use – check out this video from Linus Tech Tips for some other options.
Does the thermal paste that’s still in the applicator degrade?
Thermal paste does change over time, but fortunately, it’ll remain perfectly usable for years.
What is thermal conductivity?
Thermal conductivity is the ability of a substance to spread heat across its surface. The best thermal pastes will ensure that there is an even spread of thermal radiation so that it can be effectively dissipated over the bottom surface of the heatsink.
Why is it best to have non-electrically conductive thermal paste?
There is a lot of power being circulated near the processor, so it’s best for your thermal paste to not be eclectically conductive so that it won’t cause a short circuit.
Which tools should you have when applying thermal paste to your electronics?
This varies from person to person, but if your thermal paste doesn’t come with a spreader, you can use an old credit card to ensure that the processor surface is coated so that there is an even spread between it and the heatsink.
Are there special pastes for overclocking your CPU?
If you’re going to overclock, it’s best to select a paste that can greatly help reduce your CPU’s temperatures. This video mentions a few excellent thermal paste options for those that want to squeeze out a little more processor performance.
