Whats funny is a couple posts up was a complete plagiarizing of your post earlier in the thread. They did that just to spam their links in their sig... They must really be getting desperate.

But keep in mind that now you have near 300 watts of heat to remove. I suppose with a couple large heater cores / radiators it may be possible but it would be terry hard to cool several peltiers and the computer passively. Another thing, your electric bill is about to get a lot higher Now all of what I just said is if you want to slap the pelt right on the processor. If you want to build a chiller then you can probably use low wattage peltiers and passively cool them with large heat sinks. Now I'm not sure exactly what you mean by the formula for the prefect peltier but if you happen to be cooling an intel processor, head over to their website because they tell the heat output of the processor. Then as I have been told (but may be wrong) you want a peltier of twice the processors wattage to go right on the processor. But a pelt of any wattage can help water cooling but remember if you don't cover that however many watts of heat you have then you still must have a radiator. Also in case you were wondering I strongly recommend a pump.
