Compatibility

0 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.

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.

Source7Measurementcybenetics.com/evaluations/coolers/101Read 15 October 2026Cybenetics Cooling Solutions Test Protocol. Ambient held at 25 C plus or minus 0.5 C and 30% humidity in a climate chamber, open test bench (Cooler Master Test Bench for AM5, DimasTech Bench for LGA1851), Prime95 Small FFTs as the protocol page states, values averaged over the last 4 minutes. 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 a Ryzen 9 7900X with PBO enabled and the LGA1851 rows a Core Ultra 9 285K. The last row of each platform is the full fan speed result. The ARGB report CMCLR00099 gives slightly different values and is not stored as rows.10Reviewtomshardware.com/pc-components/air-cooling/cooler-master-hyper-212-3dhp-review/2Read 15 October 2026Tom's Hardware, Albert Thomas, review of 20 October 2025. Ryzen 9 9950X on an MSI X870E Carbon WiFi in an MSI MAG Pano 100R PZ closed case with an MSI RTX 4070 Ti Super. The ambient temperature, noise distance and paste are not stated. The review tested the Black ARGB edition. Row 1: in the 150 W test the default fan measured 37.3 dBA. Row 2: the PBO test measures the average CPU package power when the CPU reaches its limit, and the spec table prints it as more than 209 W (>209W), so 209 is a lower bound. Row 3: the review's maximum noise of the default fan is 38.2 dBA. The temperature results are in charts with no readable numbers, and the 100 W and 200 W results are only given as differences against another cooler. The text says the fan is quieter than the instrument can measure at lower power.

Heatsink dimensionsiAir coolers only. The heatsink without fans, as the maker lists it. 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. A heatsink depth that equals the depth with fans includes the fan, so that axis is not stored.

The blueprint is 160 mm deep with the 28 mm front fan, which is 132 plus 28, so this is the heatsink alone.

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. When one maker figure may include the mounting kit, such as a press release net weight above the product page figure, the product page figure is stored. An RGB edition can weigh a little more or less, so it is per variant.
