    • Excellent 240L water cooler
Style: 240L Core
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. ... show more

    • Fantastically quiet and cool
Style: 360 Atmos
Running a game, I'm peaking at less than 50c and even during peaks, I cannot hear the fans spin up. For my install, I connected all of the ARGB connectors to the controller that came with the case so that all of the lights on the case plus the cooler are controlled as one. All in all, highly recommend this over any CPU cooler I've had in the last 30 years. ... show more

    • It does as avertised for the price
Style: 360L Core White 360mm
I have this watercooler sitting on top of a Ryzen 7 5800X3D and it does what it's supposed to do. I've had it for a few months and this is my few months review. I currently have it mounted in the front of the case with tubes on top. Most people would say that's bad, but the pump is below the apex of the tubing so it's fine. The pump is well made, quiet (even at full tilt( unless you live in a quiet room, the cooling capacity is as it should it, etc. The only issue I have so far is the amount of air that is within the cooler. There is more air than I've had with other coolers mounted in the same position, of the same sie 360mm. Obviously you need air for expansion and contraction, but the amount in the system is a lot more than should be there. ... show more

    • Great budget AIO
Style: 360L Core White 360mm
Bought this based off price, works better than my old Corsair AIO. Keeps my i5-13600k cold. The only con is you can't buy more fans to match the ones that come with the AIO.

    • Beautiful and powerful
Style: 360L Core
Loving the lights, and how make the computer case pop! The fans are powerful and maintain an even airflow through the case. It installed with very little fuss and was easy to integrate to my case! For cup cooling I'm running about 50-60C well under the 89C of my last cup cooler!

Review Image by Jason Cottrell Jason Cottrell
I was torn on buying either this model or the arctic liquid freezer ii. In all honesty, I chose this model because it would arrive much quicker, and I regret my decision. I don't really care for RGB in my pc so I would have been much happier paying a little less to lose the flashy display. This was my first AIO and to be honest, the packaging and instructions are just flat out, lacking. The instructions are crudely printed with white images on the back of the black boxes for each compartment with little to no text directing you. The images are small and not very detailed with no clear guidance and their website is even less helpful. It took me a few youtube searches to finally get the process down enough to start the install. One thing that is beyond annoying is the amount of wires. The fact that the three fans aren't daisy chained together makes no sense in this day and age. The 3 to 1 wire they include is stiff and difficult to work with. The CPU plug on my motherboard is at the very top so trying to get it connected but also angled so it went behind the radiator left plenty of scratches on my fingers. For the pictures on the box for the RGB connections, you are to assume you have to either connect all of them using the 5 to 1 cable they include or the control box. If you work with RGB on a regular basis then you would know you could just connect each of the plugs together using the male and female plugs, but since this is my first time working with RGB I had no idea. After plugging everything in and connecting the pump to my cpu I turned on my PC to test everything out and at first it looked like everything was running perfectly. My temp was down, the lights were on and the fans were spinning, at 100%. I knew these were PWM fans so I tried to adjust the speed with the bios, but nothing would change the speed. Finally I decided to remove the included 3 to 1 plug and use one of my own and that, for some reason, solved the fan spinning problem. Next problem, my temps started spiking. I am running an AM5 7800X3D and my cpu usage was at 0-1% so there shouldn't have been any of the spikes I was seeing. I assumed it was the paste application since that's usually the easiest fix so I took off the pump and cleaned the paste only to notice an imperfection on the copper. There was a small black spot that wasn't a scratch and didn't feel like a groove. I tried cleaning it with isopropyl alcohol but it was not coming off so it was either from the factory or something happened during shipping. There was no protective film over the copper, just the paste applicator pattern, so I don't know for sure what it was, the only thing I knew was I didn't drop, slam or scratch it. I requested a replacement and after inspecting it for any imperfections, reinstalled it and so far it's running like a champ. Temps are steady and much better compared to my previous air cooler. I'm sorry for the long winded review but I wanted to share from the perspective of a new AIO owner and how painful the whole process was. If I had to do it all again, I would have just purchased the Arctic, but since I've already done an exchange and installed another model, I'll just keep it so I don't cost Amazon any more money. ... show more
