Cooler Master 240 Atmos High Performance Close-Loop AIO Liquid Cooler, R9|i7 Dual Chamber Pump, Customize Cover, Sickleflow Edge PWM, aRGB Lighting, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform

Great cooler, but unfortunately my 9800X3D was a bit too demanding for it and I had to put the cooler back into storage to avoid killing it in the event I need it for another project. Not Cooler Master’s fault, just mine for assuming a 120mm could calm such a beast. Could do with the ability to turn the light off, but I suppose it has a bit of charm to it.

I am still using the older version of this in another build that is run 24/7 for my security camera's and moderate gamming. It's been 4 years so far since installation and no issues or loss in cooling efficiency. I ran the computer overclocked around 60c-99c for 2 of those years.....Years later this newer model replaced it. Different fan and I'm sure different pump design/motor.The pump face design is practically identical.Installation is a breeze, and it looks like it belongs in my build.This is the BEST budget AIO water cooler.I would not recommend anyone go lower than this brand's quality for aio's because it is a liability.I've herd too many horror stories about cheap aio's leaking, bursting, or random pump fails all within a year. I would be devastated to came back to a wet ruined PC because I cut cheap on my aio.Fan n' heatsink is too loud, and a full-blown water-cooling system is too much maintenance. This device fall's perfectly in-between and the fact the previous version of this model is still running perfect in spite of being run at near max operating temps for extended periods of time and it being well past its life expectancy without warranty voiding maintenance being needed.I always keep power to pump at 50%-65%. Anything higher does not improve cooling and raises operating sound, and if it does cool better, it's by 1 degree.

An absolutely fantastic value for an AIO, there are of course cheaper alternatives like ID-Cooling' offerings for less that $60, but this still keeps my CPU cool.

Very nice, it cools down 9700X perfectly on my workstation. Doesn't feel any noise when running anything. Given the pirce, 5 star.

This is the best option for AIO in SFF cases

I own a Lenovo ThinkCentre Neo 50T Gen3 Tower with 64GB RAM, an Intel i9-12900K, and a 4TB NVMe SSD. To support four monitors, I installed a new graphics card, but the system immediately started overheating—understandably. Upon researching solutions, I discovered a major limitation: the proprietary motherboard prevents transferring the components to a larger case for better airflow. Additionally, the mounting plate for the CPU cooler is soldered to the motherboard, which made traditional cooling solutions impossible.After trying several unsuccessful cooling setups, I came across this one. The pump mounted perfectly, and I installed the fan and radiator on the exterior of the case. While it's not the most aesthetically pleasing setup, I don’t care about appearances—I’m an attorney and just need my computer to run reliably without the constant fear of overheating.As for noise, I’m still adjusting to how quiet the system is. It’s strange not hearing the fan whirring, and I often worry it’s not functioning. However, stress tests have consistently shown the CPU stays below 43°C, which is a huge relief. This solution may not win any design awards, but it gets the job done efficiently and quietly.

I’ve used this cooler in FormD T1 and with 9800X3D.I probably got a defective unit because I’m always hitting throttle during full load.COOLERMASTER support stopped answering my emails for some reason so can’t RMA it.If anyone see that, ditch the AIO for the T1 and get air cooler, COOLERMASTER’s support is a joke.

I'm a big fan of Cooler Master products and this 240mm cooler came with everything I needed for AM5 9800x38 and looks very cool when lit up and cools as I expected..
