What happens if you don’t remove old thermal paste?

Yes. The reason is that when you remove the heatsink, the seal between the chip and heatsink is broken that was previously made by the thermal paste. By leaving the old thermal paste on, you run the risk of capturing air bubbles between the two when re-seated, which will cause drastically higher temperatures.

How do you clean old thermal paste?

The best option is a microfiber cloth but paper towel will do in a pinch—it leaves behind much less material than toilet paper. As for the rubbing alcohol, the higher the concentration the better. I generally use 99% as it evaporates quickly.

How often should I replace thermal paste?

You may also want to consider reapplying thermal paste if you find your CPU temperatures are climbing.

Is too much thermal paste bad?

Putting too much paste on a socket generally won’t hurt thermal performance, because the act of tightening down the cooler squeezes out the excess. Too little paste is bad, but anything above the minimum threshold will have the same effect once the cooler is tightened down.

Can I use hydrogen peroxide to clean thermal paste?

Hydrogen peroxide is good for killing organic stuff(which is why it hurts when you put it on a cut) but it probably won’t do much more than water in this situation. Isopropyl alcohol is like $. 50/bottle and it’ll clean better than H2O2 will(and it’ll evaporate a lot faster).

How do you clean thermal paste off a CPU without alcohol?

If you don’t have any alcohol, use the toughest paper towel you can find. Do not wipe from the outside in, wipe from inside out. So opposite of butt wipes. This is to prevent the paper towel from snagging on the corners and causing a bunch of fibers to go flying all over the heatsink.
