Frequently Asked Questions (FAQs)

1. Can I clean my CPU with water?

You can either just wipe the base and the CPU clean with a dry, lint-free tissue or, for more thorough cleaning, use a lint-free tissue moistened with either a mild solution of washing-up liquid or isopropyl alcohol. Do not put the cooler or CPU under running water.

2. Should thermal paste be liquid?

Normal thermal compound is fine, easily removable and nonconducting. Some people have replaced their thermal paste with liquid metal, but they haven't noticed much of an increase in performance since the paste is that new.

3. Can you just wipe off thermal paste?

Using an isopropyl alcohol wipe, gently wipe the thermal paste off the surface. Wipe in a straight line. Repeat this process until the thermal paste is gone, using a new wipe each time. Leave it to dry for around an hour.
