Compatibility

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.

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

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.

Measured

None of 6 known

Cybenetics THETA, AMD AM5iThe THETA level for this cooler's class on the Cybenetics AMD AM5 platform with a Ryzen 9 7900X. It is rated at 30 dB(A) normalized noise, or at 25 dB(A) for a cooler that cannot reach 30 dB(A). No level means tested without a level. A cooler that Cybenetics did not test on this platform is left out. A report with a heading for this platform but no results counts as not tested.

Overall performance at 30 dB(A), AM5 (measured)iThe Cybenetics Overall Performance score at 30 dB(A) normalized noise on the AMD AM5 platform. It is average CPU power times average CPU frequency divided by average CPU temperature. Higher is better. A cooler rated only at 25 dB(A) has no value here.

Thermal tests (measured)iReviewer results, one row per test condition. Rows compare only when the test CPU, load, power and noise level match. The source note names the reviewer, ambient temperature, case or open bench, and thermal paste. Test CPU is the CPU name only, such as AMD Ryzen 9 7900X. The power limit and mode go in the load. Above ambient is stored only when the reviewer publishes it, never computed from the ambient.

DeepCool's 129 x 138 x 160 mm (L x W x H) is width 129, depth 138, height 160. A heatsink depth that equals the depth with fans includes the fan, so that axis is not stored.

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.
