is it safe to use pure alcohol in a watercooling system instead of water?

Okay, in that it won't physically harm your setup...but the heat transfer sucks compared to water. Also, some alcohols are very bad for you, and can evaporate through silicone tubing to get into your lungs. Their molecules are very tiny compared to water's.

Oh, and it can disolve some epoxy/glues that hold many system's together.

alcohol will prevent stuff from growing in your system but, like diggrr said, it's thermal conductivity sucks. you could just add some watterwetter to your water and it will stop corrosion and prevent crap from growing.

how about 50% water/50% methanol as far as cooling is concerned...

I don't recommend methanol. It can be very bad news for pets
and you, if you breathe fumes for long.

Nothing you will ever find will be better than pure water for
thermal transfer. If you want to use an alcohol to keep the
monsters out of your rig I would recommend ethanol i.e.
regular drinking alcohol. I suppose rubbing alcohol would
work, too, but I have never heard of anyone using isopropanol
in water cooling rigs?

Anyone?

Don't handle methonal. It's very bad for you. I know all R/C glow fuels come with warnings now about how it will absob through your skin and cause cancer(and other stuff). I say avoid it.

my college chem prof made me show the 10th grade chem class today some cool reactions that involve fire, I filled a bottle with about an inch of methanol then rub it around the bottle and lit a match over the bottle turned off the light and FIRE +++++ looked soo cool drool...hehe

hmm Neat. You know the pure methonal race cars use burns invisible? Maby that was some other racing fuel, but I do believe it was methonal.

I believe you are right. In fact, didn't they propose that a additive
be mixed with it so the flame becomes visible?

Burning methanol indoors is not something I would authorize.
Besides the invisible flame issue there is the toxic fume issue.

Why would anyone want to do this? :eh?:

some people love to try diffrent things! (a hint: thats why they fuc* things up...:p)
