Review Image by D XCXVLLN D XCXVLLN
The media could not be loaded. I recently upgraded to the Cooler Master 240 Core II AIO CPU Liquid Cooler, and it’s been a game-changer for my build. Installation was a breeze, and the sleek design with the infinity mirror ARGB adds a nice touch. CPU sits at a steady 44°C—impressive for the price! The dual-chamber pump runs quietly, and the 120mm fans keep everything cool without much noise. Highly recommend for anyone looking for solid performance and aesthetics on a budget. ... show more

    • The cooler is great, the included thermal paste isn't.
Style: 240 Core II
I'm very happy with the performance and looks of the cooler. It easily mounts to your motherboard (AM4 in my case) and the radiator mounted to the top of my Lian-Li LANCOOL 207 DIGITAL case using the case rails. The only thing I wasn't impressed with was the included thermal paste. The paste is more like thick putty, far thicker than other thermal pastes I've used in the past. Being so thick, I didn't want to just place a blob in the center or even a X of paste on the CPU, so spreading was the only option. I will use something else if I have to re-paste in the future. ... show more

    • Quality water cooler
Style: 240 Core II
I had a used cooler from a friend when I built my tower. I started overheating and replaced it with this one. Works perfectly and am running nice and cool. I play a lot of flight sim which takes a lot of power and cpu/gpu so keeping things cool is vital.
