Cooler Master MasterLiquid Pro 280 AIO Review

Rating: 8.0.

Cooler Master have earned a well-deserved reputation for producing quality CPU coolers. Today we are looking at their new 280mm all-in-one cooler – the MasterLiquid Pro 280. Cooler Master claim that the MasterLiquid Pro 280 should deliver unparalleled performance due to its innovative pump/waterblock, which features ‘657% more surface area’ to allow for better heat dissipation. With the inclusion of 2 MasterFan Air Balance fans as well, could the MasterLiquid Pro be a ‘must have’ liquid cooler?

With a price of just over £100 here in the UK, the Cooler Master MasterLiquid Pro 280 is not the cheapest AIO we have ever seen, but hopefully it will justify the price by giving excellent performance. In this review, we go over the build quality, installation process and thermal performance of the MasterLiquid Pro 280 before giving our final verdict.

    Great review on a average product. That’s an ugly CPU block, why on earth would you want to illuminate a couple of screwheads and what looks like a clutch pressure plate😋. You don’t describe it but from the pictures it looks like the coolant passes over the fins then up through a weird ‘Z’ bend then out through the top part of the block. When I saw that configuration and the blue light with the clear cover I thought the water filled the chamber but in the last picture I guess not.
    I’m not a fan of desktop illuminations but this cooler takes it back to basics and then some, performance wise its a Seidon 240M you reviewed in 2013 but the Seidon performed better on a hotter processor. http://www.kitguru.net/components/cooling/henry-butt/cooler-master-seidon-240m-liquid-cpu-cooler-review/
