Zalman’s ZM-STG2 thermal paste is used in this test not to favor its cooler, but because Zalman has long been our thermal paste provider. It works equally well with other cooler brands, and settling on a single substance reduces variability in testing.

Our CPU and voltage regulator pull around 300 W at full load at this O/C, using an old C0 stepping Core i7-3960X at 4.60 GHz and 1.40 V. We used this specific processor because it’s the one we can most easily afford to lose (due to heat damage) after long bouts of overclocking.

Benchmark Configuration
Prime95 v25.864-bit executable, Small FFT's, 8-threads
RealTemp 3.00Highest core reading at full CPU load (60 minutes)
Highest core reading at 30 minutes idle
Galaxy CM-140 SPL MeterTested at 1/4 m, corrected to 1 m (-12 db), dB(A) weighting


Twelve threads of Prime95 provide 100% load. We were forced to test noise at extremely close distances to stay within our meter’s calibration range.
