The H100's radiator uses a common heatercore design. Flat channels for the liquid run lengthwise from end-to-end, with thin fins filling up the space between. Each side of the radiator has threaded screw holes that can be used for mounting the radiator to your case or for mounting fans to the radiator. For optimal performance, you can use four fans in a push-pull configuration.
Included with the H100 kit are two identical Corsair 120mm fans. They are both rated to produce 46-92 CFM of airflow with 22-39 dBA of noise. While the fan controller integrated into the waterblock supports PWM controlled fans, the included fans are 3-pin.
With both fans installed, the radiator and fan combination are approximately 5cm thick.
Included with the H100 is mounting equipment for AMD (AM2 & AM3), and Intel (LGA 775, 1155, 1156, 1366 & 2011). Switching mounting brackets is as easy as removing and reinstalling four screws.
The waterblock mounting equipment is screwless. The screws for mounting the radiator to your case and installing the fans requires a Phillips screwdriver. Enough screws are provided (8) to install two fans, but if you want 4 fans in a push-pull configuration, you'll need to get more screws.
Corsair provides easy to understand diagrams in the installation guide. They're very Ikea & Lego-esque and I prefer this style of diagrams compared to the typical photo based guides provided by most manufacturers.
Compared to some of the large heatsinks that were reviewed here in the past, the waterblock/pump end of the H100 is pretty small. There were no clearance issues at all around the socket of our ASRock Z68 Extreme 3 motherboard.
By nature of design, there should be no issues with the usage of DIMMs with tall heatsinks/heatspreaders.
