Not long ago we checked out Cooler Master's newest entry in the AiO cooler segment, the MasterLiquid Pro 240. It was a really nice cooler with a brand new unique dual chamber pump design that performed admirably in the highly competitive 240mm radiator category. While truly a highly polished product with a really great design aesthetic, the Pro 240 may not be everything you are looking for as far as performance is concerned. If you find yourself thinking along those lines perhaps this next product from Cooler Master is for you? Today we'll be taking a close look at the bigger brother to the Pro 240, Cooler Master's absolutely newest product, the MasterLiquid Pro 280! This AiO is nearly identical to the Pro 240 but comes equipped with a 25% larger 280mm radiator. Follow along as we check this brute out and see how much of cooling punch it packs.
