A quick check of the Intel 7980XE's power consumption showed around 70 Amps being pulled through the 12 V rail (of which the majority of its power delivery goes straight to that central processing unit), which means that the CPU was pulling around 840 W power ( 70 Amps x 12 V) at a relatively safe 5.5 GHz overclock. Those wattage numbers saw increases of up to 1000 W in more radical 5.8, 6 GHz overclocks. These were achieved with a vCore of 1.45 V, which isn't really that high a value compared to historical Intel CPU overclocks - be these through extreme or more conventional cooling methods. Mindbogglingly, the Intel 7980XE was delivering temperature readings that were above 0 ºC, in a cooling loop that placed LN2 at -100 ºC in contact with the heat-spreader. This means the Intel CPU was able to surpass in heat production the -100 ºC of the LN2 cooling. Final overclocking values that successfully completed a loop of Cinebench's R15 benchmark on the multi-threaded test reached 6.1 GHz on all 18 cores, with Hyper Threading active.
