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

2 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 product text also names LGA2011, LGA2066 and older AMD sockets. The text is from the launch and the current spec table omits them, so they are not stored. The installation method is a backplate that needs motherboard removal.9Press articleclub386.comRead 15 October 2026Article quoting Noctua's FAQ: all Noctua CPU coolers compatible with LGA1851 and LGA1700 also support Intel's LGA1954, and no additional mounting parts are needed. The NH-L12S is listed for LGA1851 and LGA1700, so LGA1954 is stored. The article warns that low-profile coolers with a backplate mount may differ, but Noctua's statement covers all its coolers.

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.

35mm1Retailer pagequietpc.com/nh-l12sRead 15 October 2026Text: with the fan installed on top of the fins, modules up to 48 mm fit, against 35 mm in low-profile mode (fan underneath the fins). The fan sits underneath as delivered, so 35 mm is stored.

Offset mountingiThe included mount can shift the base or cold plate off the socket centre, for example toward the AM5 hotspot. An asymmetric heatsink on a centred base does not count.

Yes8Reviewaphnetworks.com/reviews/be-quiet-dark-rock-6/3Read 15 October 2026Mounting bars have two positions marked 0 and 8. The user manual calls 0 the standard position and the offset 8 position the one for maximum cooling on AMD Ryzen 3000, 5000, 7000 and 9000. The reviewer found his Ryzen 7 9700X ran cooler in the standard position.10Reviewenostech.com/be-quiet-dark-rock-6-air-cpu-cooler-reviewRead 15 October 2026AM5 mounting brackets give an offset of 8 mm: each bracket has holes marked 0 and 8, and 8 covers the CPU hotspot best.

Yes8Reviewbasic-tutorials.com/reviews/hardware-reviews/noctua-nh-l12sRead 15 October 2026The AMD brackets have two holes each, one for central mounting and one for offset mounting. On AM5 the -7 mm position is advised for the best result.

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.

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.

Light Base 900 FX case with the case fans at 30%, Cinebench 26 multi-thread. The CPU ran at 170, 105 and 65 W TDP settings. The power is the setting, not a measured value. Temperatures are the average core temperature minus the room temperature, which the review does not state. The peak-core delta T values are 73.3, 71.6 and 66.4 C at 170 W, 60.5, 49.4 and 45.3 C at 105 W and 43.5, 36.4 and 32.4 C at 65 W for 600, 1,200 and 2,000 rpm. At 170 W and 600 rpm the CPU throttled from about 200 W to 172 W during the run, so that row is not comparable with the others. Noise is a meter 10 in (25 cm) in front of the closed case, so it does not compare with Cybenetics' 1 m figures. 600 and 1,200 rpm were undetected and are not stored. The 42.9 dBA at 2,000 rpm is repeated in each power row. The paste is not named.
