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.

AM5, AM4, LGA1851, LGA1700, LGA1200, LGA1156, LGA1155, LGA1151, LGA11501Maker product pagethermalright.com/product/peerless-assassin-120-seRead 16 October 2026Intel 115X/1200/1700/1851 and AMD AM4/AM5. 115X is written as LGA1150, LGA1151, LGA1155 and LGA1156. The older installation guide covers AM4, 115X/1200 and 1700 only. The page names AM5 and LGA1851.

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.

Not available

42mm4Reviewtomshardware.com/pc-components/air-cooling/thermalright-phantom-spirit-120-evo-reviewRead 14 October 2026The review says the cooler is designed to be used with RAM 42mm or lower in height. With taller 45 mm memory the fans have to be set higher on the clips, which is a moved fan position and is not stored. The maker publishes no clearance. PCUnboxing recommends memory below 40 to 42 mm and found that 44 mm memory needs the front fan raised.

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

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.

The noise distance and the paste are not stated. Row 1: no power limit, the CPU hits its peak temperature and the reviewer records the package power the cooler held, 238 W, with a maximum noise of 45.6 dBA (spec table: Max TDP with the i7-13700K, our testing, 238W). Row 2: noise normalized to 38.2 dBA, 232 W. Row 3: 175 W Cinebench load, the text says the temperature averaged 54 degrees over the 23 C ambient, and the maximum noise was 39.6 dBA. Row 4: 125 W Cinebench load, 41 degrees, with noise below the 37.3 dBA ambient system noise and not stated as a number. The text does not say 'over ambient' for row 4. It is read that way because 41 C absolute would need a cooler far stronger than the 238 W result allows. The charts give no other numbers, so no more rows are stored.
