Hi
Im replacing an stock cooler with an water cooler. The problem is where im from we dont have 90% or more alcohol. We only have 70% (the other 30% is water). We dont have normal acetone. Our nail polish removals are acetone free and have sents in theme. I think the only solution is 70% alcohol, but what do you sudgest.

IMO, dont sweat using 70% rubbing alcohol. Some folks decry anything thats not 90+ and blessed by Franciscan monks. Do your best to keep any of it from the pins and particularly the board. Beyond that, you're just cleaning a metal plate (CPU lid).

Clean as good as possible...and make sure its buffed and dried completely.

Ive known people who used Dawn soap and water on a rag to clean thermal grease off a lid...wouldnt recommend that by any stretch, but your rubbing alcohol is 100% fine.

Hi

In Uk I use methylated spirits for a variety of cleaning jobs

it is available in many other states (using different names)

The important point is that is desolves the product you want to remove then evaporates with out leaving any significant trace.

There are lot of different thermal materials in use nowdays so I can not confirm all thermal materials will disolve in ethanol.
A plastic card can be used as a scraper if the cpu has a large metal lid rather than a small ceramic square which was on common some old cpu designs

70% or 90% ethanol is not going to make much difference in practice

regards
