Cooler Master Atmos II 360 VRM AIO CPU Liquid Cooler – 360mm Radiator with VRM Cooling Fan, 3X ARGB PWM Fans, Dual-Chamber Pump, Low Noise, AMD AM5/AM4 & Intel LGA 1851/1700, Black

Excellent product. I just want to start off saying how sleek and nice it looks, I like the 3 in 1 fan design and the super sleek pump with customizable tops you can add. It keeps my 7800x3d "cooler" than my Arctis Liquid Freezer 3 could while being quieter. Previous the cpu would idle at 42-43c in windows (still just fine) but this aio keeps it between 38-40c.. actually very impressive! While in cinnebench r23 it dropped from a max of 80c to 77.5c and did i mention, while being quieter? The vrm fan also keeps my vrms cooler by 3c while being much smaller than the Liquid Freezer. The only con I can for sure say is unfortunately the vrm fan itself can get quite loud, but only sometimes. Its random. It sounds like its out of alignment or it hitting something with a light ticking noise and that is a real bummer. I keep it at 30% and that seems to keep the noise at a minimum while also keeping everything cool.

I picked up the Cooler Master Atmos II 360 for my Ryzen 9 and wow, it cools insanely well! Temps stay super low even when I’m gaming or running heavy stuff. Setup was really easy and quick too. For having 3 fans and a pump, this is one of the quietest liquid coolers I have used. The cooler also just looks awesome. The design fits perfectly in my case and I love that you can swap out the faceplates to change up the look whenever you want. It’s a really cool touch that makes it feel more personal. Overall, I’m super happy with it and already looking forward to getting more Cooler Master products in the future.

Good cooler, keeps my ryzen 5 9600x at good temps. I like the swappable front faces on the pump. Only used the infinity mirror one so far, but I like that I have the option to change it later on if I want. I didn’t use the fans that came with it but I imagine they are good fans. I put 3 asiahorse amici pro fans on it to match the rest of the build

I bought this to replace an older Deepcool Castle 360EX I've been using for a little over 5 years now. I wanted to see what a newer AIO could do with my newer AMD 9850X3D and perhaps future CPU upgrades. Sadly, the pump on this thing is making the loudest humming noise I've heard from any AIO I've tried using over the years. It isn't trapped air, but instead the pump itself making this loud noise. The entire thing vibrates like no other as well, so I'm guessing this thing is just plain defective. I wouldn't have thought a newer AIO would be this much of a downgrade as far as noise levels are concerned. I had to lower the pump speed down to 50% to get noise levels acceptable, and even then it was still noticeable in my room. I'd gladly switch back to my old AIO after this, so I'm sending it back. That makes me sad because this AIO looks really great and feels premium overall. Fans are quiet, installation and packaging was great, but I just can't ignore that constant hum that's present.

Keeps my 9800x3d cool as a polar bears toe nails.
