Result 77.1 C with no throttling. The reviewer measured 44.7 dBA at 50 cm at maximum fan speed. The CPU power, paste name and ambient are not stated precisely, so no power is stored.9Reviewclub386.com/be-quiet-dark-rock-6-reviewRead 15 October 2026Club386 with a Ryzen 9 9950X3D on an MSI MEG X870E Ace Max in a closed be quiet! Light Base 900 FX case with the case fans at 30%, Cinebench 26 multi-thread. The CPU ran at 170, 105 and 65 W TDP settings. The power is the setting, not a measured value. Temperatures are the average core temperature minus the room temperature, which the review does not state. The peak-core delta T values are 73.3, 71.6 and 66.4 C at 170 W, 60.5, 49.4 and 45.3 C at 105 W and 43.5, 36.4 and 32.4 C at 65 W for 600, 1,200 and 2,000 rpm. At 170 W and 600 rpm the CPU throttled from about 200 W to 172 W during the run, so that row is not comparable with the others. Noise is a meter 10 in (25 cm) in front of the closed case, so it does not compare with Cybenetics' 1 m figures. 600 and 1,200 rpm were undetected and are not stored. The 42.9 dBA at 2,000 rpm is repeated in each power row. The paste is not named.

Source4Measurementcybenetics.com/evaluations/coolers/100Read 14 October 2026Cybenetics Cooling Solutions Test Protocol. Ambient held at 25 C plus or minus 0.5 C and 30% humidity in a climate chamber, open test bench (Cooler Master Test Bench for AM5, DimasTech Bench for LGA1851), Prime95 Small FFTs (as the protocol page states), values averaged over the last 4 minutes. Fans were set to reach each normalized noise level at 1 m, or 100%. CPU power is measured at the EPS connectors. The protocol states Arctic MX-4 paste for all tests. Mount: Default. The report does not publish a temperature above ambient. The AM5 rows use the AM5 platform and the LGA1851 rows the LGA1851 platform. The last row of each platform is the full fan speed result.8Reviewtomshardware.com/pc-components/air-cooling/cooler-master-v4-and-v8-3dhp-review/2Read 14 October 2026Tom's Hardware, Albert Thomas, review of 8 July 2026. Ryzen 9 9950X3D on an MSI X870E Carbon WiFi in a closed Tryx FLOVA F50 with one Noctua NF-A12 G2 intake fan, PBO enabled. With the CPU at its 95 C limit, the spec table gives the average cooled power as 237 W for the V4 Alpha, both at full speed fans and in the noise-normalized test at 38.9 dBA, which is the V4 Alpha's maximum noise in this setup. The review gives no temperature for this test. All other results are in charts. The ambient temperature, noise distance and paste are not stated in this review.
