The Ikea-like instructions was ok for the most part except the retention ring part as you can put it the other way. I didn't use the adhesive because of solder points in the back. Due to this, I had to hold the back as I tighten the screws. But as my 1st AIO water cooling, it was pretty good.

another great solution from Corsair. well made and easy to install if you have a 140mm fan mount in your case.

Overall this is a really good cooler. I had a heck of a time getting my computer to boot after installing the backplate, as it kept shorting out the CPU. After taking everything apart & realigning multiple times I finally got everything working. As an experience IT tech I found this very frustrating & time consuming.My overclocked AMD Phenom II X6 1100T runs at a cool 28 degrees. No complaints there.

Instructions are pretty easy, if you follow them. I forgot to put the back plate on, with a case with no back plate access. Big hassle to undo and then redo everything.Used it on an Intel i5 4770k Haswell CPU mounted on a ASRock Z87E-ITX in a Fractal Design Node 304 with a MSI Radeon HD 7850.It fits, if just. The reason I mention the video card, is that it only had about 1mm of clearance on the left side of the rad.Didn't really load test it or OC or anything, but it is keeping low temps. From my research the thermal paste they use is actually quality stuff not garbage like most. So I didn't use 3rd party paste but used the stuff that was included.About the only thing that would have been nice would have been a 2nd set of mounting bolts and washers. I would think in most cases you are going to put a 90mm water cooler in, is going to have a preexisting fan. Rather than waste a fan, you can mount it in a push/pull configuration. However to do so, you need an extra set of bolts and washers. I managed to find some at a hardware store but they are not black, and the washers isn't quite the same size. Seeing as you pay like 90$ for this retail, and extra set of bolts/washers that probably cost about 2 cents would be kind of a nice addition should you have a pre-existing fan and want to mount push/pull.

Using in Corsair 550D with i5 3570K.4.2 GHZ 1.2/Auto Volts m 70C Very Quiet4.5 GHZ 1.25 Volts m 80C QuietMounting Back Plate had issues with ASUS P8Z77-V PRO. Solder points on the back of the board prevent use of 1 adhesive strip and can see this being issue with other boards. Plastic back piece had to flex also due to solder points.Overall Great All In One Water cooling unit might change stock fan with Noctua A14.No pump control might bother some but pump is so quiet even at highest temps.

Id suggest getting a good heatsink like a hyper 212 evo or a noctua nh-d14. single thin radiator liquid coolers are still a little more than a joke
