2.36-inch LCD liquid cooler

The NZXT Kraken Z73 is a 360mm all-in-one liquid cooler with a 2.36-inch 24-bit colour LCD on the pump block. It supports Intel sockets from LGA 1150 to LGA 1700 and AMD AM4, AM5 and Threadripper platforms. Three 120mm Aer P fans and a 394mm radiator provide the cooling surface. CAM V4 software controls the display, pump speed and fan curves.

Sustained-load behaviour

Fluid dynamic bearings and a chamfered intake let the fans run between 500 and 2,000 RPM with a tolerance of 300 RPM. Airflow scales from 18.28 to 73.11 CFM while noise stays between 21 and 36 dBA. The 400mm ultra-low evaporation rubber tubes with nylon braided sleeves maintain coolant volume over long sessions. The pump can be rotated independently of the LCD orientation for consistent flow.

Pre-installation checks

Verify that your case can accommodate a 394mm long, 121mm wide and 27mm thick radiator with three 120mm fan slots. Confirm the CPU socket matches the supported Intel or AMD list; Threadripper requires a separate bracket not included. Ensure the 400mm tube length reaches from the pump block to the radiator mounting point. A 4-pin PWM header is needed for each fan and the pump.

Questions about this item

How loud are the 120 mm fans at full speed when the cooler runs all day?

The three 120 mm fans reach 36 dBA at 2,000 RPM and drop to 21 dBA at 500 RPM, with fluid-dynamic bearings for long-term quiet operation

What separate bracket must I already own to mount this on an LGA 1700 motherboard?

Extra LGA 1700 brackets are required and must be obtained from the manufacturer

Will the 400 mm tubes reach the radiator if I keep my full-tower case with the CPU socket near the top?

The 400 mm tube length suits most full-tower layouts, but measure from your socket to the planned radiator position to confirm clearance
