If you're looking for stellar performance in a compact system, then look no further than Cooler Master's own MasterLiquid 240 Atmos, which is 34% off at Amazon UK. The cooler's design and superb aesthetics are just the cherry on top of what is one of the best 240mm AIOs that money can buy.
In our 4.5-star review, we noted that the cooler boasted strong performance, quiet noise levels, and excellent aesthetics. Given the discount on offer here, it's unlikely that you'll find a better 240mm AIO deal at this price point, so long as you're not bothered about having a configurable display.
In the box, expect to find a pair of Cooler Master's Sickleflow Edge 120mm fans, alongside CryoFuze thermal paste and applicators, a PWM Splitter, ARGB hub and splitter, and support for all modern CPU sockets. This AIO is commonly used in small-form-factor builds for its size and performance, as the CPU block is relatively low-profile, which means you'll have no issue with clearance for any large RAM heat spreaders. Additionally, with a total radiator and fan thickness of just 52mm, it'll fit just about anywhere.
Boasting impressive results in our testing, considering its size class, the MasterLiquid Atmos 240 often performs on the same level as a 360mm AIO, without all of the bulk. Expect this cooler to be able to handle the most power-hungry chips out there. If you're using a less demanding chip, the Atmos 240 will be able to handle it with no sweat.
Cooler Master's AIO was observed as reaching 38.2 dBA when paired with a Core 17-13700K, which is plenty quiet using the default fan curves. Just note that things can be noisier when pushing the cooler to its limits. Given the performance on offer here, even if you have a larger chassis, this might still be an excellent purchase. But if you have a smaller case that can only support up to a 240mm AIO, then Cooler Master's MasterLiquid Atmos 240 becomes a no-brainer.
Given that the price has plummeted by 34% this Black Friday season, it's reasonable to assume that you'll likely not find a better cooler than this right now. Thanks to its low-profile design, it'll fit just about anywhere, and the CPU block looks great, without being outwardly garish, as many RGB-laden PC components lean toward.
