My System Specs

Default i7 860 TDP

Had a quick question that I couldnt find an answer on google.

What would the total TDP be on an i7 860 when clocked at 4ghz - 200x 20?
Vcore 1.381v
VTT 1.36v
PLL - 2.00v
PCH - 2.4v
DRAM - 1.66v ( DDR3 1600 - 7-7-7-18 1T)
Id assume other then the PCH which is offchip, that upping all those voltages must bring the TDP through the roof no and would create a great strain on the VRM along the socket?

I know stock the chip is 95w and will spike to 110w with turbo mode running full bore. But I cant seem to find any numbers to indicate would an i7 chip would output for total heat when running Vcore/VTT/DRAM voltages turned up to acheive overclocking.

165-180W assuming a stock voltage of 1.2-1.25V.

Your motherboard's VRM circuitry should be able to handle that without any trouble.
