What the Cooler Master MasterLiquid Core II 240mm

This all-in-one liquid cooler targets builders who want a 240 mm radiator with an infinity mirror pump cover and simplified cabling. It fits AMD AM5, AM4 and Intel LGA 1851, 1700 sockets for broad platform coverage. The package includes Cryo-Fuze thermal paste for immediate installation.

The spec that decides fit

The radiator measures 240 mm and uses two 120 mm fans mounted in a 120 x 120 x 25 mm frame. The pump block occupies 83 x 76.2 x 52.3 mm, so verify case clearance before purchase. Tubing length is 400 mm, allowing flexible routing in most mid-tower chassis.

Capacity and headroom

The dual-chamber pump runs at 3100 ± 300 RPM with a rated noise of 25 dBA. Fans operate between 650 and 1750 RPM, delivering 70.7 CFM at 30 dBA. This combination handles mainstream multi-core workloads comfortably; sustained heavy overclocks may exceed its thermal capacity.

Questions about this item

How does the 3100 RPM pump speed translate into real-world cooling performance?

The dual-chamber pump runs at 3100 ± 300 RPM with a rated noise of 25 dBA, moving coolant through the 240 mm aluminum radiator to keep modern CPUs within thermal limits under sustained loads.

What does the 7-pin PWM + ARGB connector actually control on this cooler?

The single 7-pin header carries both PWM speed signals and addressable RGB data, letting the motherboard regulate the two 120 mm fans between 650 and 1750 RPM while synchronising lighting effects through standard 5 V ARGB software.

Will the 400 mm tubing reach a top-mounted radiator in a full-tower case?

The 400 mm tubes are long enough for most top or front mounts in mid- and full-tower chassis; the pump measures 83 x 76.2 x 52.3 mm and the radiator uses standard 120 mm fan spacing, so clearance around the socket area is the main fit check.
