So I want to reapply my thermal compound to the HSF/CPU.
I went to the store and bought Life Brand "Isopropyl Rubbing Alcohol 70% USP", is this a good idea?
What does the USP stand for?
There was also 99% Isopropal Alcohol Life brand aswell, but it was a huge bottle and double the price...would that work better?
It also was spelled differently "propal" instead of "propyl"...I've read that rubbing alcohol would work, so I bought that.
Also checked the ingredients in nail polish remover, and it contained IsoproPYL, not pal.
Will I be OK? Or should I look for 90%+ acetone/isopropyl?

The 70% isopropyl alcohol will work. The 99% is better. Works well with a piece of a clean coffee filter. Swiffer cloth, I don't know. I wouldn't use a Q-tip. You want something lint free.

Only thing is - make sure that if the label says "rubbing alcohol", it does not contain lanolin. Lanolin will leave a residue behind.

Quote:
Isopropyl alcohol (also 2-propanol, iso, isopro, rubbing alcohol, or the abbreviation IPA) is a common name for isopropanol

Although isopropanol is sometimes sold as "Isopropyl Rubbing Alcohol, 70%" (or 91%) and "Isopropyl Rubbing Alcohol, 99%", there is no isopropyl alcohol in the United States Pharmacopeia formula for rubbing alcohol, U.S.P.


Looks like that whole naming scheme is a bit messed up, probably exact same stuff...

Take that 70% garbage back and get the 99%. If you use anything under 90%, you need to let the CPu sit for a while to make sure that it's absolutely dry / free of moisture. Or take a hair dryer to it.

When trying to remove the most solid pastes (because it dried or it was the "generic" paste that came pre-applied), I prefer to use lighter fluid.

The 70% will work, just put it on the coffee filter and rub the CPU. You will know when it is dry, it doesn't take long.

I use Heptane "trade name Bestine", but your alcohol will work fine.
