Best AIO cooler – the top liquid coolers for your CPU in 2021

The best AIO cooler is one that should make the perfect combination with some of the best gaming CPUs. Despite increases in performance-to-TDP ratios, processors can still get mighty hot these days – especially if you overclock them. If you’ve learnt how to overclock your CPU and want to put these skills to the test, you might have an easier time of it using one of the best liquid coolers over an air cooler. As more and more graphically intensive titles like Metro Exodus are released, overclocking might become more common. A good AIO cooler lets you overclock to crank out more performance with less risk of melting your CPU to a crisp.

The top cooling manufacturers have been put to the test on our test bench, with all-in-one (AIO) liquid CPU coolers from MSI, Cooler Master, NZXT, and Corsair. But why do you need to go all out on a CPU cooler? If you want to push your processor’s clock speeds to meet its potential then you need to make sure overheating isn’t a factor, and that’s where liquid coolers come in.

You might think liquids shouldn’t mix with electronics, yet an effective pump and radiator combo will move heat away from that CPU faster than you can say ‘thermal throttling’. Of course, they often feature more RGB LEDs than you can shake a stick at, so you need not worry about colour-matching with the rest of your rig.
