Cooler Master 120L Core AIO CPU Liquid Cooler – 120mm Radiator, Patented Gen S Dual Chamber Pump, PWM Fan, White LED Pump Lighting, High Performance Cooling, AMD AM5/AM4 & Intel LGA1851/1700

This thing lowered my temperature by half! I love the way it looks, and fit without issue. The instructions were pretty clear and easy to get set up.

This is a great unit and all you have to do is carefully read the instructions and you will have a great cooler at a very good price that should last for years. I bought the 120L to replace a 120m. There was nothing wrong with the 120m, but it was installed for 10 years and it is important to keep the CPU cool or it will crash. Cooler Master writes their coolers last up to 8 years, so I was pushing it. I had to remove the 120m to install the 120L, and thought it would be the same, so I did not read the instructions, which was a mistake, as it was not going the way I expected. So, I read the instructions for the 120L, which is only photos, but if you look at the photos it is easy to install. If you ignore the photos, it will not be easy to install.

This 240L water cooler from Cooler Master is replacing and Enermax made 120L RGB water cooler than served me well for approx. 2 years, but the pump developed a rattling noise that was very disturbing, and CPU temps were reaching 100C. I realized that the water pump was going to leave me. This was for an Intel 8 core I7 9700 CPU. I removed the Enermax and replaced with the Intel air cooler that came with the CPU. The system became quiet and temps stabilized around 50C which are normal. I ordered ths Cooler master that had excellent reviews. Very nice and quality built. Instl instructions were very easy to follow. CAme with the Creo fuse thermal paste that was fairly easy to apply, without any applicator. Straight from the tube. Installed everything and presto. System works very quietly and the temp stabilized around 32 C. the 2 fans are actually very quiet. Very happy with this new water cooler. The only con is the RGB. It's suited for 3 pin RGB headers while my motherboard, an Asus Z390-P model, comes with a 4 pin RGB header that is unusable. But this is a minor con. I will look for a 4 pin to 3 pin adapter cable, then this will work with RGB lights. Not an issue.

Worked great once installed. Was missing 1 screw and took awhile to find a replacement one that size. But it wasn't as hard to replace once I read Instructions after already watching alot of YouTube videos. Now PC is running real smooth

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've never been dissatisfied with a Cooler Master product and this is my first water cooled CPU. Far as I can tell it handles the temps appropriately for my AMD 9800x3d CPU. Installation was a little tricky, but that was only the fault of my case and not the cooler. For the price, I am very happy with the build quality of the cooler. My favorite part of the instructions was the bit that reads: "As a result of bubbles in the coolant, you might hear sounds coming from your cooler on the first run. Just chill out for 15 minutes and the sounds will disappear." I appreciated the good laugh after spending the time putting everything together.

Note: This review is for an Open Box unit It 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.

great looking AIO, runs quiet, makes my 5950x 10*C cooler when gaming comparing to air cool solution, however, the thermal paste that comes with the product is way to little, clearly not enough. You get like 1 full and just a little bit extra paste that means it s just for one attempt at installing the AIO and some extra, that s it. I made a mistake and couldnt secure the pump on top of the CPU in my first attempt, hence the reason I know it doesnt have enough paste for the second attempt, luckily i have some extra thermal paste from my previous build. im talking about just putting a small X in the middle of the CPU, not wasting any big amount to spread the entire cpu's surface and yet it s not enough. If the seller can give send me some extra thermal paste, i will change this review to 5 stars

I bought this after my previous water cooler pump failed. I have an older computer and wasn’t sure if this would work, but it works excellently! The instructions are hard to follow as there are only titles and pictures. Each computer model requires different replacement instructions and techniques. I had to watch a lot of videos to figure out how to get my old one out and put this in. Once I realized that the brackets are for new install only and that all I had to do was put on the thermal paste and put in the proper screw mounts (you just screw them into the slots already there), it was smooth sailing. BE AWARE- if you have installed this with your computer laying on its side, you need to stand it upright after you are done and let it sit for 15-20 minutes so the cooling fluid migrates where it should be.

Great product works very well and lowered my cpu temp from 95 Celsius to 80max under full load. But when I used the included paste it was hard and worn out so temp was still spikingto 95c I purchased another high quality paste now much better max 79c under load.

Le armé a mi esposa un PC con todos sus componentes blancos y este enfriamiento líquido combinó perfectamente con ello. Es fácil de instalar y mantiene las temperaturas en buen estado. Confío mucho en esta marca.

Work as intended…if you want better cooling performance get those expensive models…you can always check product reviews with cooling tests online like from Tom’s hardware etc.

Looks and works great and is the first cooler I have found to fit in my M/atx case. Iz gud
