Temperatures are the delta between the CPU and the ambient temperature, which the review does not state. Fan speed is set by the motherboard at 100%, 66% and 33%, measured at 12 V, 8 V and 5 V as 2000, 1300 and 650 rpm. AMD: Ryzen 9 7900X at 65, 105 and 170 W. Intel: Core i5-13600KF at 65, 125 and 170 W. The charts have no 33% bar for the cooler at 170 W, so no row is stored for it. The review says some coolers could not hold the CPU at the highest power. The review charts noise in dB with no weighting or distance, so no noise value is stored. Its text does not name the load program or the paste. The review text credits the offset mount for the AM5 results.8Measurementcybenetics.com/evaluations/coolers/112Read 15 October 2026Cybenetics Cooling Solutions Test Protocol, revision 1.8 procedure: ambient 25 C and 30% humidity in a climate chamber, open bench (Cooler Master Test Bench for the Asus TUF Gaming X670E-Plus, DimasTech Bench for the ASRock Z890 Taichi), Prime95 Small FFTs at each noise level, CPU power measured at the EPS connectors, Arctic MX-4 paste for all tests, default mount. The first four rows are AMD and rows five to eight are Intel. The CPU hits its temperature limit in all rows. The report publishes no temperature above ambient. The 100% rows repeat the 30 dB(A) results because full speed is 29.4 dB(A).
