Kraken 280mm LCD cooler for Intel and AMD CPUs

The NZXT Kraken RL-KN280-B1 is a 280mm all-in-one liquid cooler with a 1.54" circular LCD screen on the pump block. It uses a seventh-generation Asetek pump running up to 2800 RPM and two 140mm F140P static-pressure fans. The radiator measures 143 x 315 x 30mm and the copper cold plate fits Intel LGA 1851, 1700, 1200, 115X and AMD AM5, AM4, sTRX4 and TR4 sockets, though Threadripper brackets are not included.

Buyers who want a screen on the pump

This cooler suits builders who want real-time system data or custom images on the pump display and a single breakout cable for easier installation. The reinforced nylon-braided sleeves protect the tubes during handling. It is not for buyers who need Threadripper mounting hardware in the box or who prefer air cooling without a pump and radiator.

280mm radiator with two 140mm fan slots

The radiator requires space for a 315mm length and two 140mm fan positions, so case compatibility must be checked before purchase. Fan speed ranges from 500 to 1500 RPM with airflow of 33.22 to 99.68 CFM and noise of 19.4 to 32.1 dBA. The 4-pin PWM connectors allow speed control through NZXT CAM software, including a 0 RPM mode at low temperatures.

Questions about this item

Which socket should I pick between Intel LGA 1700 and AMD AM5 for this cooler?

The block mounts on both Intel LGA 1700 and AMD AM5 without extra parts. Choose the bracket that matches your motherboard socket.

What does the 2800 RPM pump speed deliver inside a case?

The seventh-generation Asetek pump runs at 2800 RPM to move coolant through the 280 mm radiator, keeping CPU temperatures low while staying quiet.

How does the 4-pin PWM fan connector limit control?

The 4-pin PWM header lets the motherboard vary each 140 mm fan between 500 and 1500 RPM, so speed and noise scale with actual thermal load.
