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

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.

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.

THETA Silver, Air, rated at 25 dB(A) because the cooler never reaches 30 dB(A). The report was evaluated under protocol revision 1.8, before revision 2.0. The ARGB report CMCLR00099 also shows THETA Silver rated at 25 dB(A) on both platforms.

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.

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.

Cinebench R23 looped for 30 minutes, steady-state CPU temperature at the end. Ambient is held at 22 to 24 C. The review calls the numbers delta temperature, stored as the rise over ambient. At 100 percent fan speed (1850 RPM) the noise was 42 dBA and the delta 68 C. Set to 40 dBA, which took a 90 percent duty cycle at about 1750 RPM, the delta was 69 C.

The 68 W test is an overclocked Ryzen 5 3600 on an MSI MEG X570 Ace, using the cooler's included fan and the Gamers Nexus standardized method. At a normalized 35 dBA (fan at 80 percent) the CPU ran 39 C over ambient. At 100 percent fan speed it ran 38 C over ambient at 39 dBA. The review's 123 W results (59 C and 58 C over ambient) are not stored because the text does not name the CPU used. Ambient and the paste are not stated in the review text.
