Summary: This cooler is on par with the H80i in temps. Pro: Price, size. Cons: Only 1,500 RPM on pump vs 2,300 RPM for H80i. I have to RMA my H80i and this H90 is a temp cooler while I wait. On the box it says 55c at 100% load on a 3770k at 4.6 GHz. Which is a total lie. My 3770k with 1.128 volts at 4.3 GHz hits the low 70's. That is with push/pull, using my extra screws from my H80i. Plus the fact that my ambient temp is 22c...

Summary: The Corsair Hydro Series H90 is designed in Denmark and manufactured in China. This is the best single cooling fan Liquid Cooling System for an over clocked Intel 4790K processor in the computer market. It has efficient 90+ cubic feet per meter airflow. It has appropriate nine centripetal vanes and the obligatory fluid bearing hub for longevity of the fan assembly. The minor wind noise is very acceptable. Have done the research, testing, and assembly.
Performance is great. The pump is dead quiet but the fan ...

Summary: Performance is great. The pump is dead quiet but the fan that comes with it is junk. On the 3rd day is started rattling. At first only when it would be on 60% power or less. So I upped the lower threshold and it helped...for 2 days. Eventually I ran the fan at full speed so that it wouldn't rattle too much as it moves up and down on its shaft. Then I replaced the fan with a 140mm Noctua which uses less power but seems to work better.
Better than the good ole' days of doing it all yourself.

Summary: Dropped my CPU temps by 15c on my 4970k, which is mildly overclocked to 4.6ghz. The problem with the plastic backplate mentioned by other owners seem to no longer exist as the model I received actually had metal anchor's in it for the mounting screws. Definitely worth the price as there are air coolers that cost equal or more than this and yet are greatly effected by ambient room temperatures. Definitely worth the money.
Summary: Installation instructions are a little vague. Same for the installation video. Once installed, the product works well. Have a computer that runs 24/7 that wasn't climate controlled during the evening. Needless to say, it was overheating until I put this bad-boy in. Now, It stays a bit cooler than the ambient room temp. BTW, this is on an Intel i5 Process running a video surveillance software.
Summary: No problems with installation. Cooled well, and was fairly quiet. Certainly better than the stock cooler. 6 months later my computer started locking up. Opened my case assuming something was overheating. Found a small puddle of fluid on my GPU and more at the bottom of the case. Fortunately, everything was working again after I dried it out and installed the stock cooler again. I am going to get it exchanged, but I don't trust it enough to put it back in my case.
Despite the Amazon description, this doesn't fit LGA 1150

Summary: This may be an amazing CPU cooler, but not for my current machine. I wanted to put it on an LGA 1150 socket per Amazon's description, however it doesn't fit. The H80 is the model that does. I ordered one and am expecting it to be terrific.
