Question: can i use 70 isopropyl alcohol to clean cpu?
Answer: Avoid using rubbing alcohol, which is just 70% IPA. ... @thekingcameron Yes, Isopropyl Alcohol will help to remove remaining residue, though I'd remove as much of it as you can using a lint-free cloth or similar before using it so you're not spreading the thermal paste or compound around and making a mess.
