yes i googled em, but don't see anyone that sell them.
fry's used to, the sales guy just said we don't sell them anymore.
what they get outlawed or something?

just wanted to get a couple but my last ditch effort will be ebay i guess

there terribly inefficient.

Can i ask what you intend to cool with them, b4 i help you set your house on fire?

The most common mistake with tec's is poor knowledge about them, and that can lead to fires.
 
welp, was actually trying to make a semi cool place that i could touch to kinda cool down. no ac at work...dang sweltering dock
wanted to underpower it just to get a little cooling unit i could slap on my forehead if need be for just a sec
wasnt gonna be plugged in continuously either

...fans can only do so much and i don't have access to ice...
 
the problem with pelts is, the hot side gets REALLY hot so it needs a lot of cooling. You are better off keeping a cool rag on your head to cool off IMHO.
 
I don't have a peltier for sale, but I got a 10 gauge shottie in the FS forum for getting rid of pesky deer flies and that which would be at the dock. LMK asap and I'll throw in some AP rounds for if you ever lock your keys in your car.

I realize TEC cooling is very inefficient, but with the advent of 32nm cores couldn't a smaller cold plate be used?

Smaller cold plate= Less energy usage right?
 
Wow, $25 for the 80W version on FrozenCPU. At that price, it gives me the urge to buy one and try a dual-loop project. Chilled liquid on the cold plate side (so if it burns up or malfunctions, it's not sitting directly on top of the CPU), and a smaller but adequate loop to cool the hot plate side.

Problem is, I would be deathly afraid of one of the pumps dying.

not to mention temperature control and condensation issues.
 
80W couldnt move the heat generated by an average light bulb, let alone a modern processor.

for quadcores you need at least a 300W tec, higher the better.
For dualcores, you can pull it off on a 226W tec.

For 80W, it would make a cool beer can chiller.

i dont use just 1.. i use like 4-5... depending on how much i want to pull at load.
 
How much cooler can a person make their CPU with a TEC?

Is possible to lower CPU temps below ambient? If so by how much?
 
Well I currently use an ultra chilltec hsf which has a 50w peltier and my i7 920 kicks its ass all over the place when I game. It can never cycle off and the fan stays on high most of the time. This will change as soon as my bitspower fittings get here and I can convert my system to water.

It's possible to cool much below ambient with a properly engineered design. TECs can be cascaded for much higher deltas.

Aigo when are you going to have pictures of that chiller (or whatever you're calling it hehe) in line and operational?

Wow, I didn't realize TEC plus cascade (cooling the hotside) could go colder than Cascade alone.

A Giant Tec system cooling a water reservoir on one one side and transferring heat to another separate water reservoir on the other side?

Sounds like a cool experiment if that is what you are really doing.

How much power does it use? What kind of temp changes are you getting compard to water alone?
