Corsair bundles in all required mounting hardware and accessories needed to setup and run the Hydro Series™ H75 cooler in you system.
With their normal attention to detail, Corsair includes well written manual in with the H75 liquid cooler. The include more than enough detail to easily get the cooler setup and mounted in your case correctly with instructions and illustrations included for all socket types supported by the included mounting hardware.
Corsair includes a plastic back plate that fits around the socket back plate on the board, used for installing the cooler to an LGA775, LGA1366, and LGA115X type socket. The standoffs with same sized screws on both ends are used in conjunction with the plastic back plate, while the standoffs with the small screw on one end mount directly to the LGA2011 socket top plate. The X-style mount plate is used for all Intel socket types. For AMD sockets, the scissor-style mount plate is used in conjunction with the black colored standoffs. Those standoffs screw directly into the stock AMD back plate. The mount ring and thumbscrews are used for both Intel and AMD-based installs. Note that the thumbscrews do not have integrated springs with them. Corsair changed the hold down design mount to use spring-less thumbscrews for the H75.
The plastic back plate is used for Intel cooler mounting only. The mount has metal nuts that lock into the sliding plastic constructs from the plate's bottom with the nut mounts sliding to accommodate the LGA775, LGA115X, and LGA1366 socket types.
Unfortunately, the nut mounts for the plastic back plate seem to be the Achilles heel for the H75 cooler. After only a few board mounts, the metal nuts began to loosen in the nut mounts, free spinning when attempting to tighten the thumbscrews eventually. From the pictures, you can see how the metal nuts ate away at the sides of the nut mounts. I had to replace the mount with a spare metal LGA115X back plate in order to continue using the cooler on my test bench.
Aside from the encountered back plate related issues, the mounting mechanism used for the H75 cooler is well designed and easy to use. You fix the back plate in place with the standoffs through the top of the board and fix the correct mounting plate to the block with the plastic mount ring. The constructed mount shown is for an Intel LGA115X socket, but looks the same for all other Intel socket types with the exception of the LGA2011 socket.
The standoffs install easily to the board, screwing directly into the back plate nuts through the board. The use of simple standoffs allows the block to be oriented in any direction within the socket.
On an Intel board, the base plate surrounds the socket's base plate, resting directly on the board's back surface. If their are any chips or components in close proximity to the socket plate, there is a risk of contact or crushing those components with this type of back plate. The all plastic construction of the base plate minimizes any contact related electrical issues with the board.
For support of the included fans, Corsair includes a 4-pin fan power splitter so that you are able to run both of the unit's fans off a single fan header or power connector. The splitter cable is black rubberized cables to to protect the cables from snagging and to give the cable a sleek appearance. In addition, eight mounting screws and washers are included to fix the fans to the radiator.
To disperse the heat from cooler's radiator, Corsair includes two of their 120mm fans, rated for a maximum speed of 2000RRM and capable of generating airflow up to 54CFM. The fan enclosure is a black plastic housing with a total of seven wide grey fan blades, ensuring generation of adequate air flow and pressure. The fan cables are rubberized, ending in a 4-pin PWM-style power connector. The fans are rated to run at 12V, drawing 0.24 amps of power.
