Don't waste your money

Pros: Good fan,rgb looks good, decent cooling

Cons: They haven't updated their argb software (master plus) since last year. And it's still in beta. The software is buggy and overall likes limited. Other companies such as Corsair and Thermal take have updated regularly. Cooler master won't even comment on it. The light on the pump/cooler isn't very bright even in Max settings.

Overall Review: If your buying cooler master argb great for the rgb. Don't. Corsair and Thermal take keep their software up to date.

Manufacturer Response:
As mentioned on your other review, MasterPlus software has not been in Beta since the end of last year. Have you flashed the firmware for the ARGB controller either? You can find it on the product page for this cooler on our US site.

Overall Review: IF YOU WANT AN RGB AIO BUY ANOTHER BRAND

Did you find this review helpful?
Manufacturer Response:
How do you have the ARGB lines wired up? Did you happen to flash the firmware for the ARGB controller? If anything, please contact our support team at support.coolermaster.com. One of our agents can assist you with troubleshooting the unit, or replacing the controller if necessary.

Lots of air bubbles

Pros: Nothing to consider since my unit failed the main purpose (cooling).

Cons: Under full load you its sounds like a water fall, i owned couple aio coolers before and i remember some producing little amount of water flow sound but its far from this unit.

i have an i7 9700k@stock and my ambient temp is 23C, the CPU is idling around 45C and under full load it immediately throttle at 100C and the clock speeds go down like crazy.

Both hoses have the same temp under load (shouldn't be the case), and one them is vibrating like crazy (lots of air bubbles i guess), It seems that my unit isn't filled up with water as it should be.

Overall Review: -i'm pretty sure this is not the case for this cooler in general and its just my unit and my luck

- I have re-pasted and remounted it couple of times just to make sure and the results are always identical

- I have repositioned the case into multiple orientations multiple times hoping to get rid of the bubbles and nothing changed

- I have tried couple of air purging methods like shaking the radiator gently while the pump is running and nothing changed

Hello Abdullah,

Sorry to hear that you receive a defective unit. I'm using one of these in one of my builds and it occasionally makes some gurgling noises. I have a similar K processor and experience temps in the low 40s at idle(although I have a pretty decent overclock). It doesn't go beyond mid 80s on full load while stress testing in Prime 95. I would suggest contact the vendor and getting an exchange. This cooler should be able to handle your processor at stock speeds.

Good cooling overall

Pros: Very nice cooling, quiet and rgb is pretty balling.

Cons: None.

Overall Review: Got this for my brother to cool his 1700x. We ended up getting a 4.1Ghz OC on it and it's running low 60c's under Aida64 extreme after several hours.

Cooler Master MasterLiquid ML240R Addressable RGB

Pros: -Looks nice

Cons: - The fans a VERY loud
- Fist cooler I received had non-working ARGB fans.
- New cooler has one bad fan (sounds like its sand in it more or less). After more troubleshooting, It turned out the sound is coming from the centre of the fan.

Overall Review: The quality of the hole cooler feels cheap. Yes, it does look amazing but that is all it has to show fore. Not happy with this product and will probably never by a Coolermaster Liquid Cooler again. Can not recommend.

May Not Be the Best AIO Cooler

Pros: LED features on the pump and fans.
Fans are super quiet.

Cons: Pump was DOA and not cooling the processor. Reached out to technical support for possible solution and didn't get an answer. I ended up submitting a RMA for a replacement. Of course, I had to pay for shipping to return it and then in about 7 - 10 business days after receipt they will ship it back repaired or issue a replacement. That is a very long time to get a replacement back to a customer without a working computer.

Overall Review: I would not recommend this AIO cooler. Return shipping for defective products should be provided in the Cooler Master warranty process, especially when it was a DOA new product.

Hello David,

How did you contact the support team? Please check your ticket(if you placed one), as I personally cleared the new supports ticket queue multiple times in the last two weeks. Newegg lists that you have owned this product for less than a regular week. How did it take 7-10 business days to send out a replacement if you haven't owned the product for 7 days yet? RMAs are processed twice a week, so depending on when we receive the defective unit, they might go out sooner. The response in your ticket should also inform you that you should have the option to contact the vendor to get an exchange, where the shipping costs would be covered(this is at the vendor's desecration though), as you are within your return window. Otherwise, you would need to go through the RMA process. The terms of limited warranty claims are clearly stated on our site, and the warranty card that you received with the product. Sorry that you received a DOA item, but there are multiple routes available to get a replacement unit.

Overall Review: This is such a great cooler that I don't think I'll ever be able to switch back to a smaller radiator. It's so quiet!
