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.

The NH-U12A is listed for LGA1851 and LGA1700, so LGA1954 is stored.

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.

32mm2Retailer pagequietpc.com/nh-d15-g2Read 14 October 2026The page says the recessed lower fin stack gives up to 59 mm clearance with a single fan. In the dual-fan configuration it recommends standard-height memory up to 32 mm. The two-fan figure is stored because the field counts all included fans in their standard position.14Reviewhwcooling.net/en/noctua-nh-d15-g2-meeting-all-our-expectations-reviewRead 14 October 2026Review of 17 July 2024: for memory modules up to 32 mm in height the front fan can stay in its default position.

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.

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.

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.

Ryzen 9 7900X on an ASUS ROG Crosshair X670E Hero, open bench, Prime95 for 20 minutes, same paste for all coolers but the paste is not named, SecuFirm2+ with the AMD backplate. Temperatures are the CPU die average as a delta to the room temperature, which is not stated and not air-conditioned. The power levels 100, 150 and 200 W are as published, and the review does not say how they were set. The cpu_power_w value is that level, not a measured power. Noise was measured at 40 cm with a Voltcraft SL-10 meter in a room of 30.4 dB(A), so the dB(A) values do not compare with the Cybenetics rows at 1 m. The 40 dB(A) rows ran at 92% PWM (front fan about 1385 rpm, middle fan about 1325 rpm). The full-speed rows are at 100% PWM and 41.6 dB(A).16Measurementcybenetics.com/evaluations/coolers/72Read 14 October 2026Cybenetics Cooling Solutions Test Protocol, revision 1.8 (20 minutes per noise level, 10-minute cool-down).

AMD Ryzen 7 3700X on an ASUS Prime X470-Pro in a Thermaltake Core P6 TG Snow, room temperature about 22 C, the stock thermal paste of each cooler, fans on the motherboard's 4-pin CPU fan header. Prime95 in-place large FFTs with the maximum number of worker threads for at least ten minutes or until stable. Temperatures are the maximum core value in HWiNFO. With both fans the maximum was 61 C and with one fan 64 C. CPU power and noise are not published (noise is a 0 to 10 rating). The reviewer says the chromax.black and the NH-U12A idle at nearly the same temperature.
