Cooler Master 120L Core Close-Loop AIO Liquid Cooler, R7|i5 Gen S Dual Chamber Pump, 120mm PWM, 120mm Radiator, White Lighting, AMD Ryzen AM5|4, Intel LGA 1851|1700 Platform

Cooling better than the 240mm aio I was previously using and fits in my case better (medium sized case). Easy to mount and install. 12900kf new build never hit 80C under stress idles at 25-30C great product and build quality. I’ve only had it installed one day so I’ll update if it fails or stops cooling this well.

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'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..

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.

My old cooling system was leaking coolant. This relaced it perfectly. Very quiet fan. It does keep the CPU cool.

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.

Great Seller ! Great Product

Does not work on 1851. The bolts on the one I purchased were machined too high and the cooler did not sit on top of the CPU to flatten the thermal paste. The metal clips for the sides are also difficult to attach. Do not buy for Intel Ultra 2.
