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

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.

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.

So far an amazing cooler that looks absolutely stunning in a white build, great for small builds and easier cools my CPU with no issues, if anything, this increases the available performance and is a great value for its money.

Upgraded my CPU to a Ryzen 7 5700X3D and it was recommended to get a water cooler and I went with this one (the 120MM fan version).First, I would recommend that you make sure that you kept your brackets on your motherboard that are around the CPU socket. I originally removed mine to install the stock fan that came with the previous CPU but luckily kept them in the box of the motherboard. The cooler will only connect to the appropriate bracket so don't buy this otherwise (or order extra).The biggest gripe I have is that it was pretty difficult to install. The connectors to the bracket hung and wouldn't catch the threads when twisting the top. It took multiple attempts that resulted in needing to redo the thermal paste (wiping off, drying, reapplying) a few times.That being said, the cooler definitely does the job for my CPU and keeping it cool. It idles around 35-38 C and I haven't see it go higher than 63 C but most games I run it's usually high 50s on average.Some have had issues with noise but I can't hear it at all. Knocked one star off for difficult installation but other than that, good fan for the price.

I was looking for a liquid cooler, Alienwares oem AIO costs $150+ I found this and was unsure if it would work as Alienware PCs tend to be really picky on what electronics they accept. Well this one worked great with no errors! The fan isn’t too loud, the materials and line feel quality. Great for the price, no complaints at all.

Works great! Simple install. Works even better then the NZXT that i had before its failure. Happy with my purchase

Note: This review is for an Open Box unitIt would have been great, if it hadn’t come with manufacturing defects. I took a chance on an open box unit for sale during Prime day. The significant discount brought the cost down to about the price of the Thermalright Aqua Elite 120 AIO, so I thought why not take the gamble. Boy was I wrong! Long story short was that the CoolerMaster product had a manufacturing defect out of the box. Luckily I discovered this when trying to mount the included fan onto the radiator, before I went through the trouble of removing my air cooler and adjusting my case for the AIO’s placement. From the pictures, you can see that only one fan screw can go in on any side, which subsequently would cause the other holes on all adjacent sides to be out of alignment. I measured carefully just to be sure I wasn’t making a mistake and even tried another 120mm standard sized fan. Nothing fit the radiator mounting holes!What irks me is that CoolerMaster makes it impossible to request an RMA for their products on their FanZone website. No option to obtain RMA support is available and customer service is likewise non-responsive. I’ve come to the conclusion that buying open box CoolerMaster products is not worth the time or hassle.Well, valuable lessons learned I guess.
