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.

Offset mountingiThe included mount can shift the base or cold plate off the socket centre, for example toward the AM5 hotspot. An asymmetric heatsink on a centred base does not count.

Fans

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.

Source7Reviewoverclocking.com/test-be-quiet-pure-rock-3-blackRead 15 October 2026overclocking.com review of 2025-03-11, values read from the bar charts. 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).
