Cooler Master 240 Core II CPU Liquid Cooler, Dual Chamber Pump, Customizable aRGB Lighting, Maintenance-Free, Quiet Operation, Easy Install, AMD Ryzen 7 AM5|4, Intel Ultra 7 LGA 1851|1700

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.

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.

Pros: Affordable price, easy installationHooked the top 120mm radiator fan to the main CFAN header and the 3-pin pump connection to my TFAN header.This works very well and is a great budget liquid cooler.I also purchased a Corsair H60 Liquid CPU Cooler 120mm and it performed HIDEOUSLY compared to this cooler. It was idling at around 43-45C and then with simple games and streaming going up to 60-70C.The CoolerMaster 120L here has been idling around 35-38C and around 42-45C for streaming and gaming.Most likely will test out another 120 liquid cooler just for kicks.

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.

Great cooler! Using this for my 5700X3D and it seems to keep temps significantly lower compared to my old nzxt fan cooler. Only complaint I have is that it does not come with the needed mounting bracket for AM4 platform. Mid install I thought i was missing a piece until i realized it wasn’t included. Make sure you buy the am4 bracket prior to this install.

Updated: Review based on 120l install on AM4 socket Ryzen 5600x in a SFF case.I have mixed feelings about this cooler. It replaced my 7 year old EVGA AIO that died.1. It does not come with everything you need to mount it to the AM4 socket motherboard. You'll need the original 2 plastic mount pieces with backplate that came with your motherboard for the included AM4 bracket to attach. This is often removed when you install other coolers. If you kept those in the box or something your good. I lost one unfortunately. I called a local PC repair shop and got the 2 replacment parts same day. You can also order them on Amazon pretty cheap.2. The AM4 bracket pieces included are really flimsy and not as well built as the other brackets included. It's nowhere near the quality of the EVGA I bracket I had. It's also a bit of an awkward install if your working in a tight space. But it seems sturdy after installing and rest of the hardware seems well built.3. The included thermal paste does not come with a paste spreader and it's the most difficult thermal paste I've ever used. Incredibly thick, very sticky, and does not spread easily. However reviews show it works really well.4. It's only been a day and most.of this review has been on on the install. I'll update the performance later this week.5. Update a week after use: Does a good job for the size, I have the 120. Ambient temps in a SFF case low 40s, high 50s under load gaming. Pretty quiet and gets the job done.

good product, good brand and good price
