I need 0C Temps! - Page 3

post #21 of 23
Not that I'm trying to hijack the thread, but you're right about the versatility of the water chiller being able to cool multiple points. You could cool your CPU and GPU to near freezing or lower using the chiller. But good luck making that water chiller fit into any case, and good luck making it look good. I don't know how well chillers do at full load, but my TEC is still sub-zero at full load. -24°C idle and -8°C full load.

The PSU isn't that expensive... TEC's don't work as well running at full voltage anyway. So if you get a 24V TEC that would normally require a high-dollar PSU to run it, just give it 12 volts and it runs a LOT more efficiently anyway. And if you get a 12 volt TEC just give it 12 volts anyway from a space PC PSU because you can run it at full power with ease. I feel at aout 65-70% voltage on a TEC comes close to the point of diminishing returns, where higher voltage will creat MUCH more heat, but only cool a little bit better. So just use a spare PC power supply that can put out the amps that the TEC will draw. At half voltage you'll never see anywhere close to the current draw at full voltage, so you'll have plenty of headroom.

Can you provide a list of the parts you have for your tec? It would be alot of work, but links would be appreciated too because I dont know what all goes into a tec. thank you!

General info on TEC's:

http://www.overclock.net/peltiers-te...tml#post625851

I've got the 437W Winstch Labs TEC which isn't available anymore.
But I believe someone on the forum got the 226 watt Swiftech and gets barely
over 0°C load temps. I can't seem to find particular links to the TEC right now, my internet is being goofy.
