280 mm LCD liquid cooler

The NZXT Kraken RGB 280 is an all-in-one liquid cooler with a 1.54" circular LCD on the pump head. It fits Intel sockets from LGA 1150 through LGA 1851 and AMD sockets AM4, AM5, sTR4 and sTRX4. The package includes two 140 mm F140RGB Core fans and a 315 mm aluminium radiator.

Sustained-load behaviour

The seventh-generation Asetek pump runs at 2800 RPM while the fluid-dynamic-bearing fans operate between 500 and 1500 RPM, moving 90.79 CFM at 34.48 dBA. A single breakout cable simplifies wiring and the reinforced nylon-braided sleeves protect the tubing during long-term use. NZXT CAM software allows 0 RPM fan mode at low temperatures.

Pre-installation checks

Verify that your case can accommodate a 315 x 143 x 30 mm radiator with two 140 mm fan slots. Confirm your motherboard provides a 4-pin PWM header for the fans and a USB 2.0 header for the pump display. Ensure the CPU socket matches the listed Intel or AMD platforms and that clearance around the 74.7 mm pump diameter is sufficient.

Questions about this item

How loud are the 140 mm fans at their 1500 RPM maximum?

The two 140 mm F140RGB Core fans produce up to 34.48 dBA at 1500 RPM, while the pump runs at a fixed 2800 RPM; NZXT CAM software can stop the fans completely at low temperatures for silent operation.

Which motherboard headers and sockets are required to run the cooler?

You need a CPU fan header and a USB 2.0 header for the pump, plus a 4-pin PWM header for each fan; the mounting kit supports Intel LGA 1700 and 1851 plus AMD AM5 and AM4 sockets.

Will the 315 mm radiator and reinforced nylon-braided tubes fit alongside an existing full-size ATX power supply?

The radiator measures 143 mm wide by 315 mm long by 30 mm thick, and the braided tubes add flexibility for routing around a standard ATX PSU in most mid-tower cases.
