Water Cooled Power Supply
lmd writes "Digital-Explosion has an article with step-by-step instructions on how to cool a power supply with water (yes, water) instead of fans/heatsinks to make it quieter. Please read the warning and disclaimer (and buy insurance if you don't have any) if you decide to try this at home."
As I recall, back in the day, the early Cray Super Computers was water-cooled
--- have you healed your church website?
Speaking from the perspective of an Electrical Engineering student, I must say this is totally insane. First of all, taking apart a power supply is bad enough if you're not careful. Second, pumping a conductive fluid through a high-voltage power converter is even more insane. Pumping water onto a processor to keep it cool is one thing, because currents and voltages on the motherboard are relatively low but a power supply has potentially lethal current and voltages. The article makes no mention of using a non-conductive fluid, nor does it make any mention of how to even correctly discharge capacitors while working with them. Anybody who tries this is seriously risking his or her life.

Not half as much as if you walked your fat burger-muching asses to work instead of driving huge gas guzzling cars.
Ok, I can't read the site because it is slashdotted, and yeah, you shouldn't trust these guys anyway, because of what they are doing.
But nonetheless, your logic is shit. I know HV electricians, pipe workers, welders, heavy plant operators, who don't even know what the internet is, but spend their lives doing stuff more dangerous that you can comprehend.
It constantly annoys me that geeks think that they know better than everyone else, just because they know the exact ins and outs of computers and networking. Yes, they are important... but there are far more important things in life.
Take a look at the later-model G3 iMacs and the G4 Cube; they have no fans. The Cube uses an external power supply, not inside the case, and it radiates heat like any adapter brick. The iMac has the power supply inside, and as hot air rises out the top it draws cool air in the bottom.
Obviously the iMac only works that way because it's also engineered not to produce very much heat; I wouldn't expect the same to be possible with your standard Athlon system. Even Apple's newer desktop systems don't run cool enough not to need fans. Still, it seems to me that some of the same concepts could be applied.
One of the reasons for having a fan on the power supply is to act as a case fan as well - it draws warm air out of the rest of the system, and cools the power supply on the way out. It seems to me you wouldn't want to just remove the power supply fan, unless you had another way of cooling the rest of the system.
Hmm, I was going somewhere with this. Oh well.
