New ways of cooling cpu chips

[Bob The Great]

Whatever those guys make...It's not enough! oy. To know that much!

Hold on-what about peltiers? I thought the technology already existed for micro-refgeration, such as using waterblocks and peltiers to push your CPU down to -22 C.

peltiers are okay, but 2 things...

1) Peltiers keep the cpu cool, but greatly increase the temp in the case

2) The cpu must always be active to keep condensation from forming.

Stick it in a fridge

j/k

kcrispin3-

I hate to prove you wrong, but peltiers (when used with watercooling) do not add temperature to the inside of the case. The excess heat created by the heat pump effect is removed through the water and out into the radiator, where it is dispersed into the air in the room. Also, with adequate insulation (mainly, using neoprene gasket material) you can put your computer into suspend mode and not worry about condensation causing a short-out, because with the gasket in place you stop the air from coming in contact with the cold CPU/cold plate. If I had the time and the money to do it, I'd watercool my system.

Gotta agree with SEALTEAMTHREE.
Have been 100% peltier for 3+ years now. In all that time I've experienced ONE instance of condensation, and that was pure stupidity on my part. When changing a cpu I forgot and left out the closed-foam plug that goes under the cpu, in the square center of the 370 socket.

A 'tuned' peltier (output is matched to the cpu wattage and the case environment) will keep your OCed cpu at roughly room temp, while the case temp levels out at about 20 degrees F over that. So long as cpu temp stays above dew-point no condensation can occur.

Right now I'm reading 77F at cpu and 91F in case with a 76F room temp. (900Cel @1.2G/72watt Peltier/Vantec6027D)
Even better results are obtained by ducting HSF output to room instead of to case interior.

I've done the peltier/waterjacket rig but prefer the peltier only route because it is simpler (fewer parts to go wrong) and cheaper. Although the water is a whole lot quieter and more efficient.

ahh, thanks for correcting me, as well as the correct info.

now that i think of it, its not a hard task to cool down teh case temperature... hmmm.....

[ryogenetic]

I am tracking on the water cooling but what is a peltier?

ryogenetic - this is some info on peltiers from arstechnica
