I bought the H100 as part of a new gaming computer setup. Living in Texas means a base temperature indoors of about 80F for much of the year and I've had some bad issues with overheating and crashing on my previous rig when playing games.Installation on an Intel based mainboard was painless (AMD looks slightly more intimidating from the manual). In fact, it was not harder than installing a stock cooler and absolutely nothing when compared with the complexity of traditional waterbased cooling systems. It comes with pre-applied thermal paste that does the job just fine, although I suspect you could get even better cooling results with high end thermal paste. The H100 installs very conveniently in the case and does not clutter up the interior at all, which I consider a definite plus.The cooling performance of the product is excellent, and better than what Corsair advertises on the box. The difference to the stock cooler that came with my processor is dramatic, double digit degrees on all settings. The H100 has three speed settings for the fans controlled via a button located on top of the part attached to the CPU. Unless you have an easily accessible case, you will likely not be changing fan speeds very much. There's apparently an additional hardware product that can be used to control the fans from an optional front panel, but I have not found it necessary to change speed away from the minimum setting unless I seriously overlock my CPU.The noise profile of the device is great, but certainly not silent, as long as it is not set to it's maximum speed setting.Some words of caution: This cooler requires some serious space and there are not many cases on the market that will work with it outside the box. On my Level 10-GT gaming case installing it meant removing one of the 210mm fans that came preinstalled to allow installation of this one. Do yourself a favor and do some research if your case has space for the H100 (The grill slightly larger than the 2 fans attached to it).Bottom line: Excellent cooler, comparatively easy installation, decent noise profile. Easiest water-cooling solution I've ever installed. Acceptable price.
