Cooler Master MasterLiquid LC240E RGB Close-Loop AIO CPU Liquid Cooler, 240mm Radiator, Dual Chamber RGB Pump, Dual MF120R RGB Fans, RGB Lighting for AMD Ryzen/Intel LGA1151

I just upgraded from a 120 mm water cooler to this 240 mm model. For reference, my processor is rated at 125 W. I purposely picked the same brand cooler with the hopes that the mounting would be identical. For my socket, this unit requires the factory mounting bracket that many other coolers, including my original cooler, do not use. It is a simple process to install, if the bracket is already on the motherboard. Otherwise, you have to find one. Luckily, they are under $10 to replace, if missing. Performance wise, I had my old cooler from the factory constantly running at 100% fan speeds to maintain decent temps. This new cooler is so efficient that I had to reduce the fan speeds to keep the temps above ambient levels. (Can’t drop below ambient in Florida unless I want a wet processor.) At constant 100% fans, this new cooler dropped my temps to below 20° C. With the motherboard now in control and adjusting the fan speed, I am about 30° C at idle and peak in the 40’s with moderate activity. This is about a 10° C drop from my old cooler for idle temps. I am not a gamer so I rarely push the processor too hard. Video production is the main thing stressing the system and that only happens in bursts. Based on some other reviews, I used a name brand thermal paste instead of what came with the cooler. I don’t know how much that changes things. The setup works great so I like it. Also, important to note that the factory paste originally installed was still extremely wet so it had not dried out. For whatever reason, the old setup was just not keeping up with the heat being generated. If I am hearing the pieces correctly, the fans are extremely quiet and I hear a little bit of pump noise. Since I am always wearing headphones, I don’t hear anything with them on. The RGB system works, but seems to have extremely limited options. I wanted a decent, budget cooler, more than lights, so I am happy with the product.

For around $70 shipped - it's hard to beat. I honestly only bought it because it was a few dollars more than paying for a new air cooler, so I gave it a shot. I was pleasantly surprised. It performed much better than I had expected it to with temps around 30-36c at idle and never over 65c under load. The only complaint that I have is that you have to be really patient with the mounting brackets on AM4 because it uses the plastic ones that come with your motherboard, and if you aren't careful and torque one side more than the other you can break them off. The other complaint I had is that, had I not done a ton of research prior to purchasing, I may not have had the hardware that came with my motherboard to put back on (thankfully i held onto it, but I know many people don't so that's something to think about) The RGB works fine and comes with all the splitters you need to get it all working out of the box... with that said, it's fairly weak - not very bright and I'm not a huge fan of the Cooler Master logo and the lights inside of it seem weak/splotchy.. but it definitely looked better than the stock air cooler I was using. I've since changed cases and my radiator would not fit on the top or front of the new case, so i've gone back to my air cooler but i'll use this in another rig sometime soon. All in all, a very solid performer for the price. Up there with many of the other 240mm AIO's i've used.

I got this for a recent build for a friend. Cooling unit was nicely packaged and included all necessary bits. Quality seems very good on everything, actually impressed me for the price-point. Plenty of options as far as color and such go too, which is nice if you're doing a themed build. You can also adjust how the LED lighting works - whether you want solid, pulsing, bright, dim, etc. I believe the system could also be hooked up to your motherboard if you have a motherboard with BIOS controlled lighting and the corresponding LED pin port. System is nice and quiet and cools nicely - this build it was used with a Ryzen 5 2600. Installation was a snap. You do need to find somewhere to hide all the wiring for the lighting, but most cases these days have good cable management and can be hidden behind the motherboard tray.

The first unit I received had a busted pump that was leaking fluid into the box. I noticed it because the fluid was green and there is a plastic baggie covering the pump and the radiator separately, and the green fluid was all over the inside of the baggie that was covering the pump. I pulled it out only to take pictures and then put it right back in the box. I promptly called Amazon customer service, who immediately ordered a replacement which turned out to be fine and have no leaks. Installation was pretty straightforward. There are a few things I didn't like about the installation: First, was the fact that the provided connections did not work with my on board rgb/fan controller module so I had to use the one provided, which has no external remote and can only be changed by taking the cable management side panel off and adjusting it to your desired rgb settings. Second, was the fact that there is no way to secure the back plate so that when you install the pump block the bolts sticking through the motherboard don't move. The bolts were free to move back and forth so you either have to completely remove your motherboard and set it carefully down so the bolts can't slide back out of the back with the bracket or have your alignment perfect when you go to seat the pump block. Having said all that, I would like to say that once installation was complete this AIO performs decently enough with the provided thermal paste that it keeps my ancient core i7 950 base clock 3.033Ghz which I have overclocked to 3.7Ghz running with 26GB of RAM on an asus x58 sabertooth motherboard at a comfortable 45-53C at idle and at 100% load it hovers around 77C. So, overall, I gave this 4 stars due to the annoying parts of installation. I didn't take any stars off for the busted first unit. I can't accurately say whether the product was defective itself or it was mishandled during shipping or storage. So, I would recommend this product based on the price coupled with its satisfactory performance. If you want stellar performance out of an AIO though, I would move past this unit and spend a bit more money on something with higher performance and quality of construction, OR go all out and spend the money for a DIY custom water loop.

10 /10

This Cooler Master LC240E replaced my Cooler Master V8. My husband replaced my V8 after 3 years of it running almost nonstop on my work computer. The V8 was doing a great job at cooling but after years of running, it was rattling. No matter what he did to lube it and cleaned it, the noise was becoming unbearable. This LC240E is silent and has been keeping my i7 at 43-48 degrees Celsius at full load and 32 degrees at idle. It even made my computer look pretty.

Just installed this yesterday and it is working great. Install wasn't too bad, there is a lot of wires to connect but that is to be expected. The instructions could be better, for example, the hardware has letters telling you when to use what piece in the instructions. The problem is the hardware itself is not labeled making the letters useless. Still most of it is intuitive. One major thing to note though is that if you are using this for your AMD cpu, you will need the brackets that come pre installed on your motherboard. This kit does not come with extra and that is how this is secured to the board. If you dont have them anymore because you used the stock cooler, you will need to buy some. I would recommend this cooler, though I haven't had it long enough to attest to its durability and reliability, it has lowered my temps and I plan to overclock my r5 2600 with this.

This cooler uses two tension levers to attach to the AM4 socket, there are 2 shallow slots with threaded holes on two sides of the water block. The tensions arm pieces get slotted in and then use screws to keep them there. I hooked the tension arms to each bracket on the motherboard and then started to carefully snap the levers into place. It takes a fair amount of force to secure them. This would have probably been the easiest block to put on out of all the AIO coolers I've used. It didn't require me to remove or modify the stock brackets on the motherboard in any way. Unfortunately this turned into a nightmare, as I was applying force to engage and set the tension lever it snapped right off and took a long chunk of plastic with it at which point there was no way I could reattach the tension arm and try again. Cooler master should scrap the RGB and put more resources into making sure the products are built solid. I ended up going to frys many cities away because I couldn't be without my computer for however long a return and exchange or whatever would take so i got a refurbished corsair h100i for cheap and the pump on that one died on me after 24 hours. Now I have two coolers i need to return, what a nightmare. I frantically brainstormed any way i could get this cooler master cooler to mount with only being able to attach brackets to it on one side. I ended up removing the bracket from the other side, taking off the back plate from the motherboard and I stooped to securing the waterblock to the CPU with freaking TIE WRAPS. My upgraded rig is actually running great now, I'm worried about not having the back plate on the mobo for support but I don't want to modify it to work with tie wraps in case I end up with a cooler of decent quality that actually works. In the end I hearken to the old adage "You get what you pay for" Cooler Master, scrap the flashy stuff on budget coolers and ensure the material used to create them are of a high enough grade to withstand basic setup, operation, and function. The setup I have here due to this cheap product is absolutely pathetic. I will likely return this after exchanging the corsair cooler for another one at Frys. For now though my machine is working. I say stay away from this one.
