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. 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.

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.

Noise at 100% fan setting (Cybenetics)iThe Cybenetics noise at the 100% fan setting, measured 1 m from the cooler in a hemi-anechoic chamber, with the pump of an AIO at full speed. Other reviewers' noise goes in the thermal test rows.

Hemi-anechoic chamber with a 6 dB(A) noise floor, Bruel & Kjaer 2270 sound analyser, microphone 1 m from the cooler at 30 to 45 degrees.

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.

Fans were set to reach each normalized noise level at 1 m, or 100%. CPU power is measured at the EPS connectors. The protocol states Arctic MX-4 paste for all tests. Mount: Default. The report does not publish a temperature above ambient. The AM5 rows use the AM5 platform and the LGA1851 rows the LGA1851 platform.

Ryzen 9 9950X3D on an MSI X870E Carbon WiFi in a closed Tryx FLOVA F50 with one Noctua NF-A12 G2 intake fan, PBO enabled. With the CPU at its 95 C limit, the spec table gives the average cooled power as 237 W for the V4 Alpha, both at full speed fans and in the noise-normalized test at 38.9 dBA, which is the V4 Alpha's maximum noise in this setup. The review gives no temperature for this test. All other results are in charts. The ambient temperature, noise distance and paste are not stated in this review.

Intel Core i7-14700K on an MSI Z790 Project Zero in an MSI Pano 100L PZ Black case with Iceberg Thermal IceGale Silent system fans, Thermalright LGA1700 contact frame fitted, the bundled TF4 paste, ambient held at 23 C, enclosed case. Noise is read with a sound meter that cannot read below 35 dBA, and its distance is not stated. Row 1: no power limit, the CPU hits TJ Max and the reviewer records the package power the cooler held. The spec table says about 225 W (Average Maximum TDP, our testing) and the text says the cooler trailed the Noctua NH-D15 by 5 W. The 41.9 dBA maximum volume is stated for this test and for the 165 W test. Row 2: noise normalized to 38.9 dBA, cooled an average of 213 W. Rows 3 and 4: CPU power limits of 165 W and 110 W with a 275 W GPU load, average CPU temperature 83 C and 70 C. Row 5: 120 W Cinebench run where only noise is reported (38.9 dBA).

CPU power is measured at the EPS connectors. The report does not publish a temperature above ambient. At 20 and 25 dB(A) the rows use the report's fixed noise levels, and the 100% row has the same values as the 30 dB(A) row because 100% gives 30.0 dB(A).11Measurementcybenetics.com/data/Cybenetics%20Cooling%20Solutions%20Test%20Protocol_en.pdfRead 14 October 2026Test Protocol Revision 2.2: Prime95 Small FFTs for at least 10 minutes per level, values averaged over the last 4 minutes, ambient 25 C plus or minus 0.5 C, humidity 30%, Arctic MX-4 for all tests, one mount per platform, AMD test system Ryzen 9 7900X with PBO enabled and Intel test system Core Ultra 9 285K in Intel default mode.
