360 mm AIO RGB liquid cooler

The NZXT Kraken X73 RL-KRX73-01 is a 360 mm all-in-one liquid cooler with a rotating infinity-mirror pump head. Three Aer P120 fans push up to 73.11 CFM at 2000 RPM while noise stays between 21 and 36 dBA. CAM software controls pump speed, fan curves and RGB lighting.

Suits Intel LGA 1700 and AMD AM4 builds

Fits Intel sockets from LGA 1150 to LGA 2066 plus AMD AM4 and Threadripper when a separate bracket is sourced. Builders who need Threadripper sTRX4 support must obtain the extra bracket themselves. Cases without room for a 394 mm radiator or a 400 mm tube run should look at smaller coolers.

394 mm radiator length decides fit

The aluminium radiator measures 394 mm long, 121 mm wide and 27 mm thick, so the chassis must clear that length plus fan depth. If the case top or front panel cannot accommodate a 360 mm radiator stack, this cooler will not install.

Questions about this item

Will the 394 mm by 121 mm radiator fit my case front panel?

Measure the front panel clearance; the radiator is 394 mm long, 121 mm wide and 27 mm thick, and needs three 120 mm fan slots plus room for the 400 mm tubes to bend without kinking.

Which mounting bracket do I use for an LGA 1700 socket?

The kit includes brackets for LGA 1200, 115x, 2011, 2066 and AM4; for LGA 1700 you must request the separate bracket from the manufacturer before installation.

Do the Aer P120 fluid-dynamic-bearing fans need lubrication later?

No, the sealed fluid dynamic bearings are maintenance-free; only clean dust from the radiator fins and fan blades periodically to keep airflow at 18.28–73.11 CFM.
