Compatibility

1 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.

Source8Reviewhardware-helden.de/thermalright-phantom-spirit-120-se-im-testRead 14 October 2026Hardware-Helden review of 2024-03-18, plain SE with two TL-C12B V2 fans, tested on LGA1700 only. Core i5-13600K at a constant 181 W CPU power, Prime95 with a fixed FFT size of 12 and AVX, in a be quiet! Shadow Base 800 DX with 2x16 GB Corsair Vengeance DDR5-6000 and the case fans at 1000 rpm. After a 30 minute warm-up the average core temperature minus room temperature was recorded for 10 minutes and normalized to a 20 C room, so the stored temperatures are those normalized values. Noise is sound pressure in dB(A) at 30 cm. Rows: maximum fan speed 47.9 dB(A) and 68.0 C, set to 40 dB(A) 70.9 C (about 1180 rpm), set to 36 dB(A) 73.2 C, 1000 rpm 37.6 dB(A) and 72.1 C. The reviewer also tried Noctua paste, which did not improve the result. The values are read from the review's result charts.

Depth runs along the airflow, fans included. Width runs across the fins. Map by direction, not by letter. Width runs across the fins, depth runs along the airflow. DeepCool's 129 x 138 x 160 mm (L x W x H) is width 129, depth 138, height 160.
