do you smoke cigarettes? if so you need to get a few caps of jel and keep them handy and clean your fan and sink about once a month. You will be amazed how much gets in there if your a smoker.
otherwise if you have a decent fan and sink your within the range not to worry to much. good jel will help but not that much.
Keep your vents open from debris and keep your comp clean.
but if you just feel compelled to replace your jel.... remember what I said. use a static wrist guard.
one little static electron and that CPU is GONE.
My thought is alcohol may contain shugar or other unwanted substances, so choose with caution.
You don't really need anything substance to clean the cpu. Use a paper towel and q tips. Lap it carefully after if you want to be extra nice.
Isopropyl is actually the best alcohol for these types of cleaning purposes because it evaporates completely without leaving any residue. Booze will obviously contain some non-alcoholic additives, even vodka(!), and ethanol (methylated spirits actually - you can't buy pure ethanol unless you work in a lab) leaves crud behind when it evaporates.
That's why isopropyl is used (by old people) to clean video and tape heads.
However, as torrentg said, I really don't think it matters in this context. A damp paper towel will do nicely.
