    I upgraded my daughters air CPU cool to this Cooler Master Liquid Cooling System and it looks great! Aside from looks, this CPU cooler is very quiet, and the CPU temperature are kept constantly low while gaming on ultra-settings. Installation was extremely easy. Best investment for our current system!

    Coming from a stock cooler, my 7700k was getting around 82 degrees Celsius while gaming. I installed this and replaced the thermal compound and now getting an average of 60 degrees! A few minor issues. The pump can be a little loud at times. It's not addresable rgb, so you wont get that rainbow pattern everyone else is doing (if this is what you're going for). If you dont have a header, using the control is not ideal. I'd like to of had a remote that I can keep outside the case if I chose to switch coolers. As I do have a header, I can control from my motherboard software. The fans could also of been better but this is your budget cooler. I may seem I'm nitpicky but it truly is a great aio. If you're not going for a particular theme and which to run stock speeds at a much more comfortable level, this is it.

    The build quality is good but I just don’t like RGB and I’m not sure if it is the cooler itself or a bios setting but I always get an error while booting saying pc fan error but I’m also running this on a 10700k with an asus rog maximus hero which is doing way better than my 3900xt paired with a asus x570 gaming e my cpu temps stay good but when I get the chance I will be upgrading to a custom ekwb kit as I buy it piece by piece

    This is my second liquid cooler. I put it on an Asus ROG STRIX pre built desktop and it took a bit of finagling but holy crap is it quiet! I have no issues with overheating on an AMD Ryzen 5800X, though I only run at stock speeds. I mostly wanted reliable quiet cooling and this system delivers. The RGB lighting is also a cool effect with my keyboard, mouse and the lighting in the desktop. Best Buy also had the best price...cant beat that!

    Easy installation on AM4 socket with clips, no need to install any backplate on the underside of the motherboard. Handles my Ryzen 9 3900X just fine with 100% load temp at roughly 80C, stays under 70C when gaming. For the price, it does a very good job. If you like LED lighting, it has that.

    These install easy, I've used several over the past few years with no failures being properly and reasonably installed. Rgb lighting is nice and colors are very good. From a fx 8320 to my current 3900x these have treated me well in several builds. Temps are always good even when the included thermal paste is used.

    For the money this is a decent cooler. I used this cooler on a Ryzen 3600 and later a Ryzen 5600X. Neither thermal throttle under load. If I were to say anything bad it would be the CPU cover on my first one came off, it was a bad glue job. The RGB lighting is decent, but not all motherboards handle it the same. Lastly if you want this cooler get the newest version of it because it has a thicker radiator, the fans are quieter and it's the same price.

    I bought this cooler for my budget build and so far it's still going. the fans show somewhat good lighting for rgb lighting but its still quiet. I have a Ryzen 3700x OC and it's keeping at good temps

    Reward after the head ache

    Very nice product but ABSOLUTELY not for the beginner (grunt) I've worked with a few AIO coolers but this 1, was a special case. It way too many wires; absolutely no exaggeration. The "stock picture doesn't show all the wires" - what a way to advertise. So after initially installing it, I had issues with the fans NOT being 1 exact color. I kept troubleshooting the "WIRES" until the fans matched. Once the fans were up and running and I put the 2nd wire on the "correct header" - we were in business. Originally I made the mistake of putting the 2nd wire after the "CPU FAN" on the header that was labeled "water cooler" = and due to that the fans were spinning at complete full speed and extremely loud. I put the 2nd header on the CPU OPT - then Life was Ok. IF you can handle allll the wires and a mini migraine to figure out the puzzle of what wire goes with other wires to make the fans colors match - Then I suggest it. If you can get this for $60 or lesser and want to deal with a little drama, then I recommend it Big Time.

    The cooler is kinda loud, granted I sit right next to my PC and this is my first AIO so I'm not sure if it's normal or not. Keeps my CPU very cool. On idle my 5800x runs at a nice 25 degrees C. The RGB lights on the block and on the fans are cool but I wish I bought the one that had ARGB

    Replaced my stock intel cpu cooler with this MasterLiquid ML240L. No complaints on this at all. Good liquid cooler I've installed into a dedicated gamer pc. Well, you know what they say about RGB. The more you have the better gamer you are. Next build with be Goth black......

    I purchased this to use with an AMD Ryzen 9 3900x cpu. Overall I'm happy with the cooling and setup for this unit. I did replace the fans with the SP120 fans that came with the Corsair 570x case I bought for my first desktop build. While everything seems to be working well, if I had to do over again I would pay the extra money to get a Corsair aio cooler. The only reason is that I dont' really have control over the RBG of the cooler other than the header on the motherboard. All of my other components are neatly controlled in iCue. I can control the motherboard, and consequently the color of the cooler RGB, but it just doesn't seem to be as adjustable as I would expect the corsair setup to be. I have control over the fan speeds through the Bios but have to boot into the bios to change the setup. I imagine if I used the Corsair aio I could control the setup in the iCue software. I think this cooler provided good value on my build and is ultimately what drove me to this one.

    This is a really great alternative to other expensive water coolers, It is able to keep my i7-10700k at a pretty cool temp even during really heavy games. Works just as good as the expensive models.

    You won’t find this same type of dual fan aio water cooler with full RGB for cheaper. Plus you get the backing of well known brand cooler master. Great performance no complaints
