240 mm AIO for Ryzen 9 and Intel Ultra i7

The Cooler Master Elite Liquid 240 is a 240 mm all-in-one liquid cooler built for high-performance CPUs such as AMD Ryzen 9 and Intel Ultra i7 processors. Its dual-chamber pump design directs coolant flow toward the CPU hotspot for improved thermal transfer. The unit fits Intel LGA 1851, 1700, 1200, 1151, 1150, 1155, 1156 and AMD AM5, AM4 sockets. A white finish and addressable RGB lighting suit bright-themed builds.

Dual-chamber pump, pre-installed fans

The pump runs at 3200 RPM with noise below 25 dBA, while two 120 mm rifle-bearing fans operate between 650 and 2100 RPM delivering 84.2 CFM at up to 39.5 dBA. Fans connect through a single 7-pin PWM+ARGB daisy-chain cable for simple wiring. CryoFuze thermal paste is pre-applied on the cold plate, rated from -50 °C to 250 °C. The translucent hexagonal pump cap allows tool-free rotation for logo alignment.

Aluminum radiator with 27 mm thickness

The radiator measures 277 x 119.6 x 27 mm and uses aluminum construction. This thickness determines whether the assembly fits your case’s mounting clearance and whether it can dissipate enough heat for your chosen processor. Buyers who need a thinner radiator or a different tube length should verify case specifications before purchase.

Questions about this item

Will the CryoFuze thermal paste need replacing after a few years of use?

The pre-installed CryoFuze paste is rated for stable thermal conductivity from -50°C to 250°C and typically lasts several years before replacement is recommended.

What limits the pump speed when the cooler runs under sustained heavy load?

The dual-chamber pump operates at a fixed 3200±10% RPM, so its speed does not scale with load; thermal limits will come from radiator and fan capacity instead.

How loud are the fans and pump when the system runs all day at full speed?

The pump runs below 25 dBA while the two 120 mm fans reach 39.5 dBA at 2100 RPM, giving a combined noise level suitable for quiet builds.
