Cooler Master 360 Atmos Stealth Performance-Driven Close-Loop AIO Liquid Cooler, R9|Ultra 9, Dual Chamber Pump, 360 Radiator, Mobius PWM Fans, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform

I recently installed the Thermalright Peerless Assassin 120 SE ARGB to cool my new AMD Ryzen 7 7800X3D processor, and I have to say, I'm thoroughly impressed with its performance and aesthetics, especially for the price. The installation process on my ASRock B650 Steel Legend WiFi 6E motherboard was surprisingly straightforward. I had read some reviews mentioning the fan clips could be tricky, but I personally found them easier to manage than expected, and the included mounting brackets worked perfectly, providing a secure and solid fit.The ARGB lighting is also a fantastic touch, looking great and adding a vibrant flair to the inside of my NZXT H6 Flow case. Performance-wise, this cooler is a real champion of silence and efficiency. Even when the Ryzen 7 7800X3D is under heavy load during intense gaming sessions or demanding applications, the Peerless Assassin's fans remain remarkably quiet - a huge benefit for maintaining a peaceful environment. More importantly, it does an excellent job keeping the CPU temperatures consistently low, ensuring stable performance without any thermal throttling. It's clear this cooler is more than capable of handling a high-performance chip within a well-ventilated case like the NZXT H6 Flow.Overall, the Thermalright Peerless Assassin 120 SE ARGB has exceeded my expectations. It offers exceptional cooling power for a demanding CPU, operates with impressive quietness, and the ARGB illumination is visually appealing. Given the easy installation, including the much-discussed fan clips, and its strong performance metrics, I'd highly recommend this cooler to anyone looking for a top-tier air cooling solution that offers fantastic value and a touch of style.

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.

This is a simple to set up AIO. The fans come with thumb screws for easy install and removal. It comes with literally everything you need in the box. Thermal paste, RGB splitter, etc.If you want a good value, and good cooling for your AM5 or LGA1700 PC, you really can’t beat the ease of use you get for the price.

Amazing!! My cpu was maxing out in temperature. When I tell you it fix it completely, it dropped it down 60!!! I would buy this for every pc I build for now on

The product quality is good for the price and it is easy to install. However, the software is not so good. After installation, I used the default settings without any settings, and it is quiet and the temperature is controlled well. If only the software had been made properly, it would have been perfect.

Great cooler, this cooler I have used in many computer builds now. It keeps the computer cool, it's very quite, and it's easy to install on AMD and Intel motherboards. The RGB is a nice bonus and it is very affordable for a 360mm water cooler.

It's a pretty decent aio cooler for the price.

I looked online for a good liquid cooler that was easy to install and efficient. I believe I found that in the Cooler Master 360 AIO Liquid cooler. Even now I can barely hear it while in use. Very silent operation. I also like the aRGB feature as well. Not so much a fan of the Cooler Master MasterPlus+ software used to control various aspects of the AIO. I'm using the software that came with the mb I purchased to control the fan speed and lighting. Other than that, I am really pleased with the cooler. Highly recommended.
