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

0 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.

AM5, AM4, LGA1851, LGA1700, LGA1200, LGA1156, LGA1155, LGA1151, LGA11501Maker product pagecoolermaster.com/en-global/products/v8-ace-3dhpRead 15 October 2026Model comparison table, Platform Support: AMD model AM5 / AM4, Intel model LGA 1851 / 1700 / 1200 / 1151 / 1150 / 1155 / 1156.

The base list holds every socket the two models support. The schema cannot hold sockets per variant.2Press releasehartware.deRead 15 October 2026Intel models support LGA 1851, 1700, 1200, 1151, 1150, 1155 and 1156. AMD models support AM5 and AM4.

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.

Heat pipesiAir coolers only. Number of heat pipes. A U-shaped pipe with two ends in the fins counts as one. A T-shaped pipe with three ends, such as Cooler Master's 3DHP, also counts as one. The maker's count wins over a review or Cybenetics count.

61Maker product pagecoolermaster.com/en-global/products/v8-ace-3dhpRead 15 October 2026Heatsink: 2 x 3DHP / 4 x SCCHP. A 3DHP pipe has a third end but is one pipe, so the count is 6. Cybenetics' spec box says 8 heat pipes, which is not stored. The page gives no pipe diameter. Impulse Gamer says 8 mm for the 3DHP pipes, and Tom's Hardware has an 8 mm and 6 mm claim only in a reader comment, so no diameter is stored.

61Maker product pagethermalright.com/product/peerless-assassin-120-se-v3Read 14 October 2026Heat pipes: 6 mm heatpipe x 6 units.

Fans

1 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.
