The highest purity I've ever seen is 70%.
The vast majority of the impurity in commercial grade alcohol is water.

No you need an actual ground. If the case is left plugged in this would

Bottom line: 70% is too impure for this task.
I hesitate to use even 90% for this. The last time I used 90% isopropyl

Huh?!? I've cleaned numerous CPU-heatsink surfaces with 70% isopropyl,
never had any problem heck, I clean optical lenses with it, in the
form of those eyeglass wipes you buy by the crate at Costco.
Hey there,
He has a 3.2 Ghz CPU which is much more then this 3800 but the only
thing that the 3800+ is good is that it has 2 cores but still same low
share ram ( I had one of these in the past).

As my measurement data in the post I just sent hints, there are serious
practical problems -- aside from the direct economic ones -- that restrict
the utility of such high-purity alcohols. There's probably no point using it

Make sure you make a note in which direction all the fans in the PC are
blowing. Usually there is an arrow on them which tells you which way
they blow but you can also feel it by holding your hand in

Bad plan. Canned air generally blows dust into areas that you don't want it.
