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

1 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 manual dates from 2023 and has no LGA1851 page.

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.

Heat pipesiAir coolers only. Number of heat pipes. A U-shaped pipe with two ends in the fins counts as one. A T-shaped pipe with three ends, such as Cooler Master's 3DHP, also counts as one. The maker's count wins over a review or Cybenetics count.

No1Maker product pagecoolermaster.com/en-global/v4-alpha-3dhp-black.htmlRead 14 October 2026Text: unlike most four-pipe coolers with direct contact, the solid copper base covers more surface area. So the pipes do not touch the CPU.

No1Maker product pagescythe.co.jp/category/product/cpu-cooler/air-cooling/high-end/scmg-6000Read 15 October 2026A thick copper base plate absorbs the CPU heat, so the heat pipes sit in a base plate and do not touch the CPU. Stored as false.

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.

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.

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. The cooler never reaches more than 30 dB(A), so 30 dB(A) and full fan speed give the same row.

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 the AM5 platform and the LGA1851 rows the LGA1851 platform. The last row of each platform is the full fan speed result.8Reviewtomshardware.com/pc-components/air-cooling/cooler-master-v4-and-v8-3dhp-review/2Read 14 October 2026Tom's Hardware, Albert Thomas, review of 8 July 2026. 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.
