Best AIO Coolers 2024

You could be looking to extract the maximum sustained clock speeds from your Core i9-14900K or Ryzen 9 9950X when it finally hits but equally you might want keep that tiny, affordable PC of yours running as quiet and cool under load as possible. Either way, there are some key considerations to keep in mind when you’re looking at finding the best AIO (all-in-one) cooler available for your new PC or if you need a great option after seeing how well top CPUs can handle such a heavy load.

It is, however, a much more convenient and less expensive option over a custom liquid cooling loop. And traditionally at least, AIOs have generally been able to deliver lower CPU temperatures with less fan noise over air coolers—though that’s not always the case today as some of them really are getting quite large.

Make sure your PC case has enough room for an AIO cooler; ideally, you want it at the top or back of the chassis to push CPU heat out. Most AIO coolers are designated as one of three sizes, which roughly correspond to the length of the radiator and thus imply how many fans you need: 120 (one fan), 240 (two fans!) or 360mm (three 120mm fans).

AIO coolers also available in sizes ranging from 140mm, to the more common 280mm and less so, all of which BUILDS′ offers. The rule of thumb is that the larger the radiator (in most cases), better it cools. Of course, cooling capacity also depends on other things like radiator thickness, materials and fan/pump performance—but you get the point.

A 120mm AIO should be good enough unless you are using an unfriendly core CPU( >5-6 GHz speed) as well not looking to overclock it. However 12th and 13th Gen CPUs from Intel is more stressful in term of cooler. And AMD’s Ryzen 7000 series, although much less thermally challenged than Intel chips in recent years, aren’t exactly cooling dreamboats either. As such, you’re getting better temperatures and slower-spinning fans as with any 240mm AIO cooler at best cooling performance but not fitting in all cases.

One more choice is setting up a custom cooling loop, this will need some mega amounts of cash and as well if silent operation together with low temperatures are crucial to you. Learn more about how these perform and look (good!) in our Blue Shift build feature. Keep in mind, these are always significantly more expensive over all other typical cooling alternatives and exponentially harder to assemble/install as well you will want double the components at minimum for a full GPU/CPU loop making future upgrading of parts such like your graphics card far/far more complex.

Don’t forget about the thermal paste (or a different type of TIM) that you will need to use with your AIO cooler when searching for the best AIO. Even box coolers include the stuff now, either in a tiny syringe or pre-applied to the metal cold plate. However, to ensure you are getting the best thermal transfer possible between your CPU and cooler plate, we have gone ahead and tested many products for hours on end in our labs so that stand back when it comes down to choosing which one is right for a custom build or all-in-one loop of liquid cooling.

New Coolers Shown at Computex

That meant lots of other new AIO coolers from Computex were using some kind of display. DeepCool, ADATA, Noctua, Hyte and a number of other companies displayed new or soon-to-come coolers. Stay tuned for our reviews of most all the new models in coming months, many likely to find a place on this page.
