Okay - having read up, i'm interested in bunging a TEC onto my setup. Not after massive subzero temps or anything, just some nice chilly temps

I'll be using a Zalman CNPS9700 - yes, i want to use this with an aircooler!

CPU in question will be a Core 2 Duo E7200, TDP of 65watts

The TEC in question is the CP1-12726, 243.5watts @ 15Vdc, 68* Tmax

So, the calculation works out at:

(1 - (65/243.5)) * 68 = 49.84*c

That should be adequate, no?
