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

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

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.

In the noise-normalized test at 38.9 dBA the AK620 G2 cooled an average of 242.5 W. The temperature limit is 95 C, which every PBO air cooler reached in the maximum test, but the review gives no temperature for this test. All other results are in charts. The noise distance, ambient and paste are not stated. The review gives 42.4 and 41.9 dBA as maximum noise for the AK620 G2 and AK400 G2 'respectively', which is not stored because the pairing is unclear.11Reviewhwlaboratory.com/2026/05/07/deepcool-ak620-g2-review-air-cooler-pertama-bermotifkan-serat-kayu/2Read 14 October 2026HW Laboratory: Ryzen 9 9950X on an ASUS ROG Crosshair X870E Hero, open bench at a room temperature of 25 C, KingpinCooling KPx paste, Cinebench R23 10-minute loop with PPT, TDC and EDC limits opened, Curve Optimizer -20, boost +200 MHz, scalar x10, thermal limit 95 C, AM5 offset mount.

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). The charts give no other numbers, so no more rows are stored.10Measurementcybenetics.com/evaluations/coolers/110Read 14 October 2026Cybenetics Cooling Solutions Test Protocol, ARGB edition.

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.

Dimensions and weight

4 of 4 differ

DimensionsiAir coolers only. The cooler with its included fans in the standard position, without the mounting kit. Height runs from the bottom of the base to the top. 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.

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.
