Standing tall as one of the best value processors around, our AMD Ryzen 7 5800X review saw it praised at launch for incredible performance, let down only by its higher MSRP and incremental performance upgrades over the Ryzen 5 5600X. These days, you can pick up the 5800X for a more than reasonable price from practically any retailer offering PC parts, but you'll need to grab the best CPU cooler to pair it with because there aren't any AMD-branded freebies in the box.
As with any custom PC build, you'll need to check the clearance inside your PC case to ensure you have enough space to fit these choices, especially the larger air coolers. Still, even with the slimmer solution of an all-in-one (AIO) water cooler, you need enough room to mount the included radiator and its fans. Nevertheless, it's a fantastic 8-core processor that's still available brand new for custom gaming PCs, so let's check out my picks for the best CPU coolers for the Ryzen 7 5800X.
Best air cooler
Noctua is a legendary CPU cooling brand for a reason. The NH-U12A is practically silent while efficiently keeping your 5800X cool while idle and under heavy load. It measures 158mm tall, so ensure the side panel of your case has enough clearance for this chunky air cooler and that your RAM won't be obstructed.
Best for silence
The Dark Rock Pro 4 TR4 is a ridiculously quiet air cooler, bordering on complete silence. For the benefits of silent running, yomustto consider its lofty 163mm height. If you're looking for ultra-quiet fans and have the space, the Dark Rock Pro 4 is the winner.
Cheapest AIO
Thanks to its tiny pump head, the Arctic Liquid Freezer II 280 is perfect for saving space inside your case versus some larger air coolers. It's an affordable solution that drops the RGB-laden aesthetics for pure function and remains one of the best choices for almost any modern build.
Premium AIO
Our Kraken X73 review praised its powerful liquid-cooling system alongside the gorgeous RGB pump with its infinity mirror effect. It's more expensive, but it'll keep your 5800X from getting dangerously hot while looking stylish.
Maximum RGB
I've used the Capellix several times in custom builds, and it's the ultimate choice for RGB fanatics. Featuring customizable lighting on the 360mm radiator fans and pump head, all controlled by Corsair's companion app.
Budget air cooler
The Scythe Fuma 3 is as cheap as it gets before sacrificing quality for air cooling the 5800X, and it only stands 154mm tall, so it won't wholly tower over your whole motherboard.
The 5800X is so great that I bought it myself (but..)

While it's technically outperformed ever so slightly in pure value by its more lightweight sibling, the Ryzen 5 5600X, I still can't resist recommending the 8-core Ryzen 7 5800X whenever it's on sale. I even bought it for my personal gaming desktop, but there is a glaring oversight that you likely noticed when buying one yourself: there's no CPU cooler in the box.
The best CPU cooler for the Ryzen 5800X depends on your needs and case size. You might want to look at something ultra-affordable, like the Scythe Fuma 3 for air cooling or the Arctic Liquid Freezer II AIO to keep the costs down. My top pick, the Noctua NH-U12A, is a super-quiet air cooler with incredible performance if you can spare the space inside your PC case.
I usually stick with AIO coolers in my machines simply because I'm a sucker for aesthetics and RGB. My go-to choice would be the NZXT Kraken X73 with a radiator appropriate for whatever case I'm building in. Clearance is crucial for any CPU cooler, especially the chunkier air-cooled variants, so double-check your available space for clearance over other components like low-profile RAM.
