I found this old peltier. It is attached to a heatsink, and has a small fan on it. It seems to work. So how about if I slap it on my P4. How big a risk am I taking? I have no clue what watt it is. Someone was using it to cool a fish tank. :D

Hmm...I'm going to venture a 99% geuss that your P4 will be dead.

Nothing decent sized will have a small heatsink and fan on it.

I'll agree, your probably looking at a sub 30 watt pelt, not nearly enough to cool the P4, although the P4 would probably survive due to built in safeguards, I still would NOT advise you use it..

Thanks for your replies guys. That's why I asked. I would never have thought that something producing cold woldn't cool as much as a heatsink and fan only. The heatsink and fan is about the same as a stock amd fan and heatsink. Is there someway to check how many watts it is with a volt meter?

Is there any numbers of anything written on the side of it?

you coul use ohms law for an idea..

V = I x R
R = V / I
I = V / R

V= Voltage
R= Resistance
I= Current

true, but how would he know how many amps/volts it's using/rated for?

You wouldn't know rated specs, only the current performance characteristics, you can normally measure two portions of ohms law, and calculate for the 3rd, no matter what the 3rd is, wattage can also be calculated using ohms law, HERE (http://www.electrician.com/resist_calc/watts.htm) is an online calculator for watts.

get a multimeter rated for 20A. But my pentium 4 has run with out heatsink before and not fried. BEcause I thought the stock HSF was touching but it wasnt. It locked up but didnt fry.
