Base materialiThe surface that touches the CPU: the heatsink base or the AIO cold plate. Plating counts, so nickel-plated copper is not copper. Direct-touch heat pipes are the contact surface, so they count as copper unless plating is stated. The direct-contact heat pipes field records the design.

Compatibility

2 of 3 differ

CPU socketsiSockets the maker lists as supported in its spec table, compatibility list or guide, written as cpu_socket writes them, e.g. AM5 or LGA1851. List each socket on its own, so LGA115x becomes LGA1150, LGA1151, LGA1155 and LGA1156. When the maker names the sockets of such a family, list only the ones it names. A socket that needs a separately sold or requested mounting kit is left out. A new socket that the maker lists with no extra kit counts. LGA2011-v3 and 2011(V3) are written LGA2011-3. Threadripper sockets use AMD's names, so TR4 is written sTR4 and TR5 is written sTR5. sTRX4 and sWRX8 are sockets of their own.

RAM height clearanceiAir coolers only. The tallest memory module that fits under the cooler with all included fans in their standard position. When the maker gives different values per socket, store the lowest and name the others in the source note. A heatsink that does not reach over the memory slots has no height limit, so the field is left out and the maker's statement goes in the source note.

Fans

2 of 2 differ

Included fansiFans in the box that cool the heatsink or radiator, one row per fan model. A VRM fan on the pump block is left out. Speed, airflow, pressure and noise are the maker's figures for one fan at full speed, in the fastest mode and without a low-noise adapter. When a range is published, the top of the range is stored. Count is the number of rotors, so a unified frame with three 120 mm rotors counts 3 with size 120. Min speed is the lowest speed while spinning. A zero RPM stop is not stored. FDB and S-FDB are fluid dynamic. HDB is hydrodynamic. Cooler Master's Loop Dynamic Bearing is loop dynamic. If the maker gives airflow only in m³/h, convert with 1 m³/h = 0.5886 CFM, round to one decimal and say so in the source note. Connector is the fan's power lead. A separate lighting lead is not counted, and a maker cable or adapter in the box that ends in a 4-pin PWM plug counts as 4-pin PWM, even when the fan's own lead is proprietary. For an air cooler with one fan, the maker's noise figure for the cooler is the fan noise. A figure the maker does not label per fan or in total counts as per fan. When a maker table prints noise for the whole cooler with no per-fan label and the maker's own data sheet for the same fan gives a figure, the fan data sheet figure is stored.

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.

WeightiAn air cooler with its included fans. An AIO cooler as one unit with pump block, tubes, radiator and fans. Mounting hardware is left out when the maker states it separately. When one maker figure may include the mounting kit, such as a press release net weight above the product page figure, the product page figure is stored. An RGB edition can weigh a little more or less, so it is per variant.
