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.

Pump power connectoriHow the pump gets power. A pump wired through a supplied hub or cable uses the plug at the motherboard or PSU end. A pump powered from SATA with a separate 3-pin speed lead is SATA power.

Powering the pump: the pump SATA power connector goes to a PSU SATA power connector, and the 3-pin pump connector goes to the CPU_FAN or AIO_PUMP header. A note says the fan-fail warning may need disabling if CPU_FAN is unused, so the 3-pin plug carries the pump speed signal. GinjFo also says a SATA connector is needed for power. The pump is powered through SATA, so sata_power is the closest option.9Reviewginjfo.com/dossiers/tests-materiel/composants/refroidissement/watercooling-aio/test-kraken-plus-280-de-nzxt-20260916Read 15 October 2026A SATA connector is needed for power and a USB 2.0 header for CAM.

Fans

2 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.

Three fans at 29.3 dB(A) add up to about 34 dB(A), which fits. The maker's fan data sheet itself is on bequiet.com and was not opened.

The temperatures are the table values per rpm, which the How We Test page says are CPU-Z averages. Noise is from a Tadeto sound level meter. The 600 rpm noise is published as <30.2 and is stored as 30.2. The ambient temperature, bench or case, paste, meter distance and the pump setting are not stated. The noise table has one column per rpm, so the same noise applies to the 253 W and 153 W rows. The review prints the rows without a Cinebench version in the temperature table.6Reviewclub386.com/how-we-testRead 15 October 2026Cooling section: Core i9-13900K reference CPU, CPU-Z average temperatures, Tadeto sound level meter, Cinebench at 600 rpm, 1,200 rpm and max rpm across 153 W and 253 W modes.

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 publishes no temperature above ambient. The AM5 rows use the Ryzen 9 7900X with PBO enabled and the LGA1851 rows the Core Ultra 9 285K in Intel default mode. The Intel 35 dB(A) row (86.8 C) and the 100% row (78.6 C) are 8 C apart, while the fans only differ by about 200 rpm. The values are stored as printed.

The CPU was set to 65, 181 and 253 W. Each cooler ran in PWM mode, at 100% and at 50%. After a 30 minute pass the highest temperature of the pass is shown as Delta T, the difference to the ambient air. The ambient value, the case or open bench and the PWM curve are not stated. Fan speed and noise were logged during the three runs, with a sound meter 50 cm from the cooler. The noise unit is printed as dB and the weighting is not stated, so the values are stored as dB(A). The 100% and 50% noise figures are one value per setting in the chart, so they repeat in every power row. The text gives 38.5 dB for the 253 W PWM run and 44 dB at 100%.9Reviewginjfo.com/dossiers/tests-materiel/composants/refroidissement/watercooling-aio/test-kraken-plus-280-de-nzxt-20260916Read 15 October 2026GinjFo, review of 16 September 2026. Core i9-13900K on an ASUS ROG Maximus Z790 Hero, open air, temperature from Intel XTU. Package power was held at set values up to 330 W with every cooler at full potential. The Kraken Plus 280 covers the CPU up to 280 W. At 330 W the CPU hit thermal throttling and the temperature reached 100 C. The chart values are not in the text. Noise was read with a sound meter 25 cm in front of the radiator while fans and pump rose in 10% steps. It ranges from 32.1 to 52.6 dBA, and passes 52 dBA at full speed. The pump alone at full speed is 39 dBA, which is not stored.
