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 - Black

Bought this cooler to replace a defective one from a rival brand that lasted all of three weeks... My temps went from 99 degrees to 30 while gaming on common games like COD/Battlefield. While playing high use games like Star Citizen I was peaking at 70/60 degrees. Specs aside the look, noise level and value for money in what I got were next to none. Makes zero noise and as stated the cooling performance and functionality is great. LEDs work well with 3rd party software so syncing all my LEDS was simple and easy

Works silent and great. Very good temperature and looks slick.

I bought this for my gaming pc and paired with a razer 9 series. It is very silent and keeps the cpu nice a cooled. Over the top quality!

Building a beast of a PC and went with this cooling solution for my I9 14900KF. Was really easy to install and getting good temperatures on the CPU. Also added a different cpu bracket for the derdded CPU bends but had no issues even with some overclocking.

I bought this AIO after seeing many reviewers recommend it for SFF builds. The low pump height is great in my NCase M2 vertical GPU set up, and installation was straightforward which is another big plus. In terms of performance, My R9 9950X3D sits around 50 °C at 30% fan speed while idling, and reaches 80–90 °C under full load with fans at 100%, typical cooling performance for a 240mm aio. The stock fans are solid, but not the best. I swapped them out for Phanteks T30s for non-RGB look and more airflow. Unfortunately, the pump noise is a deal breaker for me. The pump is very loud, but other reviews mentioned a quiet pump, but that’s definitely not the case with my unit.

This cooler was so easy to set up, I was amazed! It took no time at all, and I was ready to go. Now it keeps everything perfectly chilled, just the way I like it. Couldn't be happier with this purchase. Highly recommend it!

After installation and checking temps, it's a great piece of kit, however... The back mounting plate is faulty, even tightening up everything it still sits loose. I managed to fix it using non conductive washers, but I shouldn't have to do this out of the box. The fans are also a real problem. There is no support for the screw that mounts it to the radiator. You can easily bend the plastic of the fan until it breaks by over tightening. Whereas a solid body fan would have worked better here, and that's what I've done. I had x2 rgb coolermaster 120mm fans from my current setup, and they've replaced the sickle ones that come with this unit. Lastly, it's very difficult to tidy all the wiring. It's excessive. There needs to be a way where the body of the fan has connection points for custom length rgb cables instead of the standard input/output rgb cables that litter your pc case. All in all, if you're good at fixing small problems, you'll get it working. The cpu temps are excellent (I'm using thermal grizzly duronaut).

Great product. Does its job perfectly - keeps the CPU cooler super-quietly. These ship with AMD fitting and Intel - the first one we received came with 2 x AMD kits on no Intel kit (guess which one we needed???). Amazon sorted this in record time though and the replacement unit was spot on.

Fungerar som beskrivet. Bra och flexibel lösning med stöd för både AMD och Intel.

Très satisfait de ce CoolerMaster Atmos 240. La pompe est totalement inaudible, ce qui est un vrai plus pour un setup silencieux. Les ventilateurs restent relativement discrets, même à 100 %, ce qui n’est pas toujours le cas sur d'autres AIO. Côté performances, il gère efficacement un i5-13600K, même en charge élevée. En été, dans un appartement à 30 °C, j’observe quelques pics à 92 °C, ce qui reste acceptable vu les conditions et son TDP fixé à 181 W. Le tout est installé dans un boîtier MicroATX Fractal Design Meshify 2 Mini, qui offre un bon flux d’air malgré son format compact. Bon compromis entre silence et refroidissement, surtout pour un processeur aussi énergivore.

高消費電力のIntel Core i9-14900Kをしっかりと冷やしてくれてます。 アイドル時：37℃～39℃ Cinebench(マルチ)：77℃～79℃ ※室温20℃で測定。

Works great. Keeps my 9800x3d cool. I would definitely buy again. I've been using it for several months now. So far so great!

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.
