yeah large res's just pro long the inevitable.
Btw: I really really like my res, small and passive=sweet

me thinks 3 things, kind of liquid you have, amount of liquid in the loop, and kind of cpu you have. Or maybe I'm wrong and its none of those.

I didn’t see the Guru3d report, but other reviews I’ve seen with similar numbers are reporting the total system load, which is usually determined by metering the power through the main power cord. So that includes everything...cpu, video, board, drives, and power supply losses.

Your rated voltage is 1.3625 volts. By increasing to 1.4 you’ve increased the max power output from 65 watts to 70 watts. So your voltage change is minimal. Overclocking also produces only small increases in power use. For example, an Athlon 64 that’s overclocked by 12% will suffer only a 5% increase in power consumption. Overclocking simply doesn’t increase the power draw as much as people think it does.

Considering all these factors I think the 100 watts I estimated is really the most you’ll pull. And remember...that’s a GOOD thing! The less the better.

**also, the stock voltage for a 6700 is 1.1v not 1.35v, so the THD is rated at 65W@1.1v... +an increase of .35v roughly= [i dunno]

...That said, why does the water heat up soo fast then? It just doesnt seem right that 100w would heat up 1 1/2 qrts of water that quickly....or that 2 x 120cfm fans on a radiator would only give what seems like minimal gains, compared to no fans at all.

The typical voltage of the E6700 is 1.1v but the normal operating range goes from 0.85v to 1.3625.v. The processor can pull as many as 75 amps if necessary. You can get 65 W of power through many combinations of voltage and current.

If you know for sure that you have 1 1/2 quarts of water then I don’t know why the temperature is going up so fast. There could be other issues…inaccurate sensors, maybe bad flow...no way to know without having the system in hand, so I guess you’ll just have to keep on investigating.
