You do have to worry about it all evaporating though.
Oil has been done, but it's not anything like as efficient as water. The high viscosity makes it hard to pump, and it has poor thermal characteristics compared to water.
For anyone considering transformer oil - make sure it doesn't have PCBs.
maybe somebody should try pure hydrogen gas, it probibly wouldn't be good if it leaked, but for cooling performance it would be interesting.
I did see a Liquid Nitrogen report at Tom's Hardware guide before, the temps were crazy (we're talking -160C here with a 1Ghz overclock), but its simply not practical.
and the problem with chilling is condensation..
it's all fun and games

No!!! Hydrogen is EXTREMELY explosive. Never put it near your computer unless you want to turn it into a mini Hindenburg (along with your house).
Helium has very high heat capacity and is safer, but the very low density of it makes it ineffective compared to water.
Here is a list of common liquids and their specific heat capacity. The higher the number the better. Anyone want to use milk in their cooling system?

I thought the I WANT IT INTERNAL was related to the psus .. i guess what blue assumed
was correct. heheheheh.
Either way its more risky then cpu and gpu cooling. I would be much more careful about
buying a water cooled psu then cpu and gpu water blocks etc.
I also have my doubts of how effective they are at cooling the PSU, looking at the design of one of these PSU's the water never actually enters the cpu, but sits on the end of a very long heatsink to keep the water a nice long way from the zappy stuff.
Now, you can get away with this sort of design on a Zalman cooler because it blows air through the fingers of the heatsink causing a large surface area cooling effect, but with this design the heat has to travel all the way along the heatsink before it reaches the cooling area..
so you're going to have a very hot bit next to the electrical gubbins, and a cooler bit near the water cooling.. this doesn't strike me as terribly effiecient..
If there's all that heat near the electrical gubbins, isn't that going to travel around the case, increasing the ambient case temperature?

hahahah, I know that, thats why i didn't consider it safe. I would only be interested in it for experimental purposes only. But your damn right about that, you would need to make sure that not a single pipe is leaking or you'd have silicon and steal frags sticking out of of all 6 surfaces of the test room.
The only problem with milk would be calcium build up around the pump and radiator i think, i imagine it would be good at first but would end up deterioating the system over time. :/
Yeah but it would have strong bones.

No doubt you could make your very own cheese
Water is better than milk in any event.
Water. fresh 4.19
Milk 3.93
Assuming it's copper, the thermal conductivity is 390W/m-K. Over a distance of say 0.1m (10cm) you'll see a 1 degree rise for every 3900W power. Even in a 1kW PSU the contact area would only be 0.25C hotter than the water end.Now, you can get away with this sort of design on a Zalman cooler because it blows air through the fingers of the heatsink causing a large surface area cooling effect, but with this design the heat has to travel all the way along the heatsink before it reaches the cooling area..
Alternatively you could just use heatpipes.
th psu i was talking about used heatpipes ! if i could be bothered to fnd pics i woul but i cant
either way there has been watercooled psu's for sale for around 2 years now and theres been diy projects older than that
a fan will always make a noise i want a bigger more powerfull psu as my rails are slightly low and i want it silent no noise atall !
so why not go for a convection passive PSU?
because thats extra heat in the pc case ....
i have a watercooling system that is alot more than your average watercoolin system ! and has plenty scope to remove lots of heat
so im currently cooling my cpu and nb
next im gonna tec my cpu and gpu , plain water for the nb and hard drives (in a watercooled silenceing enclosure)
and then the psu !
that should leave only the motherboard produceing heat really and hopefully it wont be hot enough to cause instabillity which i doubt very much as all heat from everything else will be removed from the equation
i just want total silence as im a light sleeper and i hate excess noise and heat i need my room to be fairly cool
and i like being able to overclock everything a fair bit more than i was able to with air cooling and things are running cooler so thats a bonus too
