Is it possible to calc an overclocked processor heat output?

Based on the stock TDP?

for instance E6600 65TDP

If you had 3.5GHz @ 1.3v. Would this work?

65W/1.2v = 54.17 * 1.3 = 70.42W *3.5/2.4 ~103W?

Is that a good guesstimate?

Thanks

Well, TDP isn't the true heat output, so using it wouldn't be ideal.

Heat output and power draw increase expotentially with each increment of voltage.
What you need is voltage, amperage and an answer to the question how much energy C2Ds actually use for their purpose.

Actually, that is exactly what TDP is for. The industry uses it as a guideline for all their heatsinks and case designs. :lol: 

If you want to get a good estimate of TDP for your processer, please head over to the extreme PSU calculator, where you can enter the new MHz and vcore of your overclocked CPU, and even adjust for 50% to 100% TDP, based upon how you think you'll use the CPU to get a good idea also of how much PSU power you might need.

You may estimate the power using this formula:
P = C * V * V * f where
C: capacitance of the CPU
V: the voltage applied to CPU
f: the frequency of the CPU
