Nice price for perfomance and quiet fans. Mounting was a little fiddly though.

I really do like this cooler, and I prefer its styling to its successor. -1 for a bit of a finnicky install. Nothing horrendous, but a little more effort than I like.

Great cooler for my 7700k. Very easy to install, had to fiddle around with the position of the radiator but that was mostly a problem with my case. Keeps the cpu at 35 degrees idle and under 80 degrees under load, overclocked at 4.8ghz

Very good Liquid Cooler and looks slick!

A pretty good WC for the price, looks good, and keep my 7700k below 70º C in heavy game/flight simulator load. CPU at stock clocks, but at 30ºc ambient temperature.

A perfect AIO that supports every major socket out there in the market. It's a must have item for enthusiasts who intend to overclock their system, or for those wanting to drastically cool down a really hot processor running at idle. It's cooling performance is incredible and consistent while operating at little to no noise (when tuned correctly in the bios).

Installation can be a bit tricky, given the provided length of the tubing (and the case you have), but the ingeniously-made bracket allows for almost any orientation, so it shouldn't be a big issue. The pump also has a very soft, but delightful, white LED illumination to show the Cooler Master logo.

The radiator is incredibly lightweight and compact coming in at less than 20mm thickness, meaning it should be compatible with every case that supports 240mm rads and leave a low footprint. The uniquely shaped blades on the fans can also pass through copious amounts of air at low RPM.

All in all, this AIO is simply a fantastic buy for the compatibility list and value for the money, particularly for early adopters of the AM4 Ryzen platform; as this is currently one of few AIO's out there for it.

I got the updated version with am4 instructions (and a sticker on the box), the installation took time and effort but overall great temps for the price (i got it on sale).

Keeps my CPU cool under heavy load at ~65 C. Has a sketchy mounting bracket for the AM4 socket. It's very quiet, even when my CPU is under heavy load.

I got Mine for $60 and Wow, It keeps my i5 7600k Overclocked to 4.5 GHz UNDER 40 Degrees. The White LED looks great too.

Great AIO, i havent heard the fans spin clearly and have managed to even hear the liquid from the radiotor since the fans have been so quiet. Great radiator and with the fans its a full 2 inches so consider that when thinking about clearance. This was a problem for me though on the visual end. I ordered this from newegg and had it delivered. When it came in there was a dent in the box and a dent in the radiator. It has not posed as an issue during installation or while in use but a minor con.
