MasterLiquid Atmos 360 Black CPU Liquid Cooler - AIO Water Cooling System, Dual Chamber Pump, Pre-Installed Sickleflow 120 Edge Fans, Addressable Gen 2 RGB, LGA1700 & AM5 Brackets

Just FYI, I ended up replacing the fans with the (Cooler Master SickleFlow Edge 360 Single-Frame) - which is basically the same fans that come stock on this but as a single frame and with a better looking X-frame bracket on the back (this was done for totally visual reasons because I needed to create a pull setup). The result has been absolutely exceptional imo. On to the actual product. The fans that ARE included on this are top tier and the radiator + pump has performed very well. Idle temps are crazy low with my specific setup, high 20s to low 30s in the summer on a 9800X3D! I was concerned about the pump initially as for the first few hours after setup it was making unusual squirting noises as the liquid cycled for the first time (you should exchange if this persists, mine went away after about a day of running). The unique integrated pump design in the header is extremely quiet, unlike what I've heard of the Artic Freezer III. The header on this actually looks significantly better in person, I was worried as it looks pretty tacky in pictures. No complaints here at all so far, highly recommend. As of 2025, different testing sites have cited this and the 280 equivalent as among the best performing AIOs overall. Despite that, it's a shame that it doesn't seem to garner much deserved attention though over some of the more gimmicky or overpriced AIO offerings from other brands.

I upgraded from a 240 AIO to the Cooler Master Atmos 360 and my temps dropped significantly! I regret not upgrading sooner! The pump design is so beautiful! Install was simple. Fits well on my motherboard and chassis. Fans are super quiet. This thing cools my i9-13900K so well. If you're considering upgrading or looking for a new build, this is a great option!

Super solid 360 AIO cooler. I bought this to cool a 9700x inside of a Phanteks G500AA, and it does the job super well. I did have an issue with a bearing on one of the fans, but Cooler Master customer service sent me one out after verifying the purchase which was super quick. I still have the fan sitting on my desk, but I'm not sure if I'll install it. The temps with just 2 fans running is actually pretty good(I think like 1c higher?). Fore the price, I dont think you could get a better cooler. The RBG is solid, super quiet, easy to install. Would 100% recommend

Amazing cooler, easy to install, amazing speed and cooling, great lighting. Only complaint is the weird thermal paste spreader just put thermal paste on like normal don’t use this thing and it’s perfect.

Worked exactly as advertised. Excellent quality. Very satisfied.

Definitely does its job and is fantastic, however ease of installation was not easy at all, they give you a digital manual which does not really help at all with setting up. Otherwise it’s great.

I've been using it for about a week and so far, I'm really liking it. I've used some AIO coolers in the past and this one was the easiest to install by far, and probably the quietest as well. The packaging is very well done and the little template they give you to apply the thermal grease should be standard on all coolers. I've paired it with an AMD Ryzen 9 9950X3D processor and it keeps the temps in check with no throttling. The only negative I can say about this is cable management... it's a bit of a mess. It'd be a lot nicer if there was a single cable going in/out for the fans instead of three separate cables. It's not the end of the world, but other products do this aspect a little better. Make sure you have some zip-ties and/or cable sleeves handy when you go to install. The only thing I haven't tested is the RGB functionality because lighted fans aren't something I'm interested. In all honesty, I should have done more research, since the Atmos Stealth is similar but without the RGB. I just didn't know the Stealth version was an option at the time of purchase. But if RGB is something you're interested in, you have a lot of options with this cooler and it comes with several accessories for different types of connections and controllers.

I looked up what aio would pair with 9800x3d the best and this was what popped up. It's quiet and looks really nice along with keeping her under 66°c running borderlands 4 on badass in 4k. My first aio so I have nothing to base this off. I would buy it again, and already told friends.
