Thermoelectric cooling ( Peltier effect)

[FNfal]

Any one used this before or have experience with this for cooling CPUs in PCs .

"Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current. Such an instrument is also called a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC). They can be used either for heating or for cooling (refrigeration), although in practice the main application is cooling. It can also be used as a temperature controller that either heats or cools.[1]"

Did some reading on this and there were actually reviews that said watercooling offered the same performance at much lower power consumption. the Idle temps was good, but at full load on high end CPU's and GPU's produced to much heat and that was 10+ years ago.

And you can get Beter cooling then watercooling at a higher price but will work for 24/7

Same technology as a normal Fridge. keeping a CPU at 30Deg C 24/7 but I expect that it will be expencive in terms of your electric bill.

Yes I have a few lying around. Still needs a small (thus noisy) fan to be effective, It also needs and use a lot of power in itself so fairly inefficient if you look for power savings. As coolers they worked well and maybe can make a come back in its own on the more modern low power thus lower heat cpu's and gpu's in smaller devices.

PS if you are looking for one to play with there are many domestic min coolers and fridges using them and searching a pawn shop could yield some results. Look for those very small beverage can cooler or mini fridge heat/coolers or cooling bags.

Yes for mission critical systems and I can confirm that TECs require a fair amount of sustained juice to be effective (although TECs do cool very quickly), which means that TECs are not a cost effective solution for PCs or even servers but if you need to cool a Cray or other supercomputer you probably wouldn't be crying about your electricity bill before adding TECs to the equation.
