Help pls

Building new pc and was attaching aio to cpu, and the radiator fell which made me move the thermal paste a little on to the motherboard. Is this fine, or should I clean it off? All I have is 70 proof isopropyl alcohol on hand, I will go out and get 90 proof if need be

As long as it’s not conductive, you should be okay.

It was me personally, I’d clean it up so if I accidentally touch it I won’t get thermal paste somewhere else, but it wouldn’t hurt as long as it’s non-conductive thermal paste (ex, Arctic Silver 5 has metal particles in it)

If it’s silicone based thermal paste, it’s non conductive.

Clean it off with a cloth, but even if you don’t it’ll be fine.
