72W Peltier for a Celeron D 346 & i3-540

post #1 of 2
Thread Starter 
I'm pretty new to this, and I've got a bunch of question smile.gif


Both chips uses around 72W at max TDP.

Will I be able to cool the Peltier using a stock HSF? How good is a stock Intel HSF compared to an AMD stock HSF?

Since I'm inputting about as much heat as the Peltier can dissipate at the max, do I need to worry about the Peltier or CPU overheating even with proper cooling?

Will condensation form when my CPU idles?


Thanks in advance thumb.gif

At best case, the TEC you'll use that might give you a 20°C drop in temps will use about 75W in consumption.

Total heat that would have to be removed (again in the best case scenario) will be 147W. The Intel heat sink, from what I remember, they are a flat circle completely aluminum. Those barely handle the 72W of a regular CPU. Stock AMD heat sinks with heat pipes might be able to handle it but heatsinks for TEC cooling take alot more considerations.

Aslong as you keep the TECs hotside less than like, 70°C, it won't really hurt the TEC. They are sometimes rated for higher, but they are priced differently for that. Anything that puts the TECs cold side higher than ambient, it will completely negate any benefit from TECs.

If you're cooling the CPU below ambient, condensation will probably form. I always insulate with TECs unless they have something that monitors dew point.

No problem! lol
