240 mm liquid cooler with LCD

The NZXT Kraken Elite 240 is an all-in-one CPU liquid cooler built around a 240 mm aluminium radiator and two 120 mm static-pressure fans. It targets enthusiasts who want both thermal headroom and a 2.36 inch square LCD that can show custom images, animated GIFs or live system data through NZXT CAM software. Intel LGA 1851, 1700, 1200 and 115X sockets are supported alongside AMD AM5 and AM4. Threadripper sTRX4 and TR4 require a separate bracket that is not included.

Installation ease and common issues

A single breakout cable connects the pump to the motherboard, reducing cable clutter and simplifying the mounting process. The pump runs up to 2800 RPM while the fluid-dynamic-bearing fans operate between 500 and 1800 RPM, producing 17.9 to 30.6 dBA. Builders should verify that the 275 mm radiator length and 30 mm thickness fit their case, and that the 81.9 mm diameter by 59.5 mm tall pump block clears nearby components such as tall memory modules or VRM heatsinks.

Pre-order compatibility checks

Confirm that your motherboard socket matches the listed Intel or AMD platforms before ordering. Ensure the case can accommodate a 123 mm wide by 275 mm long radiator with two 120 mm fan slots and that there is sufficient clearance for the pump block dimensions. Check that a 4-pin PWM header is available for fan control and that the power delivery can support the pump and fan combination. Threadripper users must source the appropriate mounting bracket separately.

Questions about this item

How do I confirm the 640 x 640 LCD is showing live data after I finish the build?

Open NZXT CAM, enable a hardware-monitor layout on the 2.36" screen and watch the CPU temperature update in real time; the pump should sit near 2800 RPM and the two 120 mm fans will spin between 500 and 1800 RPM under load.

What ships in the box and what must I source separately for a Threadripper build?

The cooler includes the 240 mm radiator, two pre-mounted 120 mm F120P fans, pump block with 1.54" LCD, Intel LGA 1851/1700/1200/115X and AMD AM5/AM4 brackets, plus a single breakout cable; a Threadripper sTRX4/TR4 bracket is not included and must be purchased separately.

Which Kraken Elite capacity matches a standard dual-fan 240 mm radiator footprint?

This model is the 240 variant — radiator dimensions 275 x 123 x 30 mm with two 120 mm fan slots — so it fits the standard dual-fan 240 mm mounting pattern found on most mid-tower cases.
