The cooler itself is great It keeps my 5820k very cool even if it is overclocked. But the corsair link software is total garbage. It uses up a lot of resources and fails to work most of the time. Also it doesn't always report the temperatures of the temp sensors very accurately all of the time.

Does a great job of keeping my Haswell at decent temps when i overclock. It was a breeze to install and works like a charm

Four stars does its job really well just the pump is a little too loud. But great design looks great in my build.

LOVE IT. Cant go wrong with this cpu cooler. Keeps the cpu cool under OC and load.

I really wanted to get the Kraken, but the price was better for this, and it fit my needs a little better. It can get a little loud under load, but nothing too distracting! Keeps the temps low, and looks way better than an air cooler! Easy installation!

Quality build and works great! No problems so far.

This is the first AIO product that i've ever owned so I can't compare it to others out there but it definitely helps cool my CPU under load. I replaced the stock corsair fans with my own just to keep everything in uniform.

Keeps my 4790k cool, stays quiet, and the link software works nicely in the background.

Small Update

You can definitely hear the pump whirring when the CPU is @ 100%, but since that doesn't happen unless something is going wrong in software, it shouldn't be considered a practical or real world issue.

Rip. discontinued, got mine a week before and it's working perfectly. Keeping the CPU around 20c idle, and under 35c under 100% load (Prime95) I've yet to see it go into the 40c while Gaming, only during Prime95 after an hour.

Incredibly easy to install. Keeps my CPU incredibly cool no matter what I throw at it.
