Hexagonal pump design for Ryzen 9 and Ultra i7

The Cooler Master Elite Liquid 240 is a 240 mm all-in-one liquid cooler built around a dual-chamber pump that directs coolant straight to the CPU hotspot. It supports Intel LGA 1851, 1700 and earlier sockets plus AMD AM5 and AM4, making it suitable for high-end desktop processors in a standard black finish.

Upgrade from air coolers

The pump runs at 3200 RPM while staying below 25 dBA, and the two 120 mm fans operate between 650 and 2100 RPM with a maximum of 39.5 dBA. Pre-applied CryoFuze thermal paste is rated from -50 °C to 250 °C, so the swap eliminates the need to source compound separately.

Fits 240 mm radiator mounts

The 277 x 119.6 x 27 mm aluminum radiator occupies two 120 mm fan slots and comes with frosted-blade fans pre-wired on a single 7-pin PWM+ARGB connector. Tool-free adjustable pump orientation and pre-installed brackets simplify alignment on supported Intel and AMD platforms.
