Atmos Stealth AIO CPU Liquid Cooler – 360mm Radiator with 3X Mobius PWM Fans, Dual-Chamber Pump, Low Noise, AMD AM5/AM4 & Intel LGA 1851/1700, Black

Bought this to replace a different pump that went bad. The RGB colors are great, looks very sharp and ties into my computer well. I didn’t need to use the software as my RGB motherboard controller did the job, but their software is an option if you need it. This pump actually ran cooler than the original pump I bought ever did! I was running about 90c which is way too hot and my CPU was throttling. Once this was installed it was down to 65c!! That’s a huge difference! Setup was easy, good directions, and it had all the adapters for an AMD or Intel CPU. It was also cheaper than a lot of others I looked at, so a great value!

Simply Amazing. I've never been one afraid to spend on my PC, but also valued reliability and above all, noise. As such, I've firmly been in the Noctua (with the occasional deviation) air-coolers, culminating most recently in the NH-D15 G2... an absolute beast of a cooler that overwhelmed everything in my case, made it hard to work on anything, and was way noisier than I expected. So after a TON of research, this replaced it. ...and man, is it quiet. Definitely nothing flashy about it if you're looking for RGB (there is zero), but I have RGB in the other elements of my case - I don't need it everywhere. What this DOES give me is the ability to keep both fans and pumps turned down to inaudible (on a 9800X3D), which I love. I can hear the pump if I put my ear next to it, but with the case on? Nada. All this, while dropping the ambient temps of my CPU by around 5C at idle, and way more at load (while being quieter at every level). Highly recommend if you value silence.

I bought a Costco Prebuilt PC (Aegis R2) with a I9 14000f and a 4070 Super the CPU Cooler was a radiator/FAN. I mostly play WoW on almost ultra settings and my CPU Temp was idle about 74c and under load could range from 80c-94c! so not optimal for long term gaming, with a little dust it was riding the higher end of the temps more often. I decided to finally break down and buy an AIO Cooler and its been absolutely impressive, Idle at desktop is 25c-30c, idle in game With my setting cranked to ultra I am 45c-54 and under complete load in game I am around 54c-61c max. I have also run the Cinebench CPU Benchmark and max Temp throughout the test was 74c. Another note any Temp below 70c My PC is almost Completely silent after the install and even above that its quieter than it ever was. I purchased the 360 Atmos because I could fit it and it was like $20 more than the other unit. It was a snug to fit into my case opening however once it was in it fit very nicely. It is definitely a high quality item that was packaged very well and everything included was well labeled. Also I did not see it mentioned anywhere but there is thermal paste included. I ended up ordering some Artic thermal paste for the install I did end up using the one I ordered. The only "CON" if you can call it that is that the installation instructions are pictures only and if you aren't 100% sure what you are looking at it can be a touch confusing as they give you extra cords for different ways to set up the LEDS. it hung me up for a bit however there was a fantastic YT tutorial that gave in detail instructions for this exact unit and he even talks about all of the extra parts as well. I am intermediate in PC building knowledge and it took about an hour to replace the radiator setup. I did accidentally follow the wrong wire and unplug a wrong wire and had to do some tracing to find out what it was and where it plugged into that was my bad lol... All in all I would absolutely recommend this unit to anyone looking to cool their CPU down price is 100% reasonable for what you get.

I'm using this to cool my 7950x3d. Granted, it doesn't need a 360mm AIO, but I care more about the noise the fans make. The Atmos Stealth is quiet as a mouse, I can barely hear it during day to day productivity tasks. It keeps temps. low in the 50s. The only time the fans become audible is during gaming sessions. Note, at full blast, these fans will be loud and sound like an industrial blower.

Ice cold. Quiet. Easy to install. Hadn't used liquid cooling before, but upgrading from an intel gen 7 to a Ryzen 9800 required new mounts. This works, keeps the new processor cooler than the old Cooler Master fan+radiator setup on the old processor and is quieter. Plus it's cheap.

Been great. Temps are stable at 37-42° F depending on what programs I run. It's worth looking in to.

This cooler has top tier performance for it's price point. My computer temps running a 9800x3d CPU and GTX 5080 for GPU has been under 60c even on the highest of loads. Mounting this cooler was standard as other coolers, yet the instructions are clear and easy to follow. This product doesn't have any RGB however that is what I prefer, since I dislike any RGB lighting nowadays and with the Stealth in this cooler's name, it has no RGB lighting which is perfect. Would recommend other Cooler Masters AIO for future pc builds as well.

Works great. I have a 14700K. Was using a nice air cooler (DeepCool Assassin 4)because I wanted to have very limited RGB and cables but it had a very hard time keeping up with the Intel cpu. Switched to this and temps dropped 30-40 degrees Fahrenheit. Looks nice as well. Easy setup. Fans even came pre attached to the cooler which was a nice touch

Très efficace. Avec un fan, j'avais des températures au environ de 90 degrés Celsius et maintenant, même avec des jeux comme Cyberpunk, je reste en dessous de 35 degrés.

Right, this Cooler Master AIO. It's not a toy, it's a thermo-nuclear chiller. It's doing a proper job of keeping my R7 7800X3d (or i9, whatever the bloody thing is) cooler than a vampire's chest. High performance, quiet fans that don't whine —that's five stars straight off the bat. The packaging was top-tier. Built like a brick privy, too. Radiator and fans are solid. They even packed a proper tube of thermal paste—the good stuff, not that cheap muck. And everything is lousy with labels, so even a muppet could figure out where the bits go. Top marks for that Now for the pain: the installation. This pump is a beast, looks like a small grenade, and shoving it into that Corsair 2000D case felt like trying to put a rhino in a handbag. The whole rigmarole with the Strix X870i was a headache, so clear some space and pour a stiff drink before you start. And the wiring? Diabolical. It's a rat's nest waiting to happen. They give you a Rolls-Royce of a cooler, then cheap out on the bloody cable management. Sort it out, Cooler Master. Practical Verdict: If you need serious cooling, this is the business. Just be prepared for a bit of a scrap getting it fitted. The performance is worth the struggle.

Super quiet and keeps my overclocked and undervolted 13700k super cool ! 😎

Great Cooler Worked well on my 9800x3d .The cooler arrived very quick and it was a decent price

Well made AIO with no unnecessary lighting.
