Installation and Finished Product
The first thing you are told to do is to go ahead and grab the anti-vibration strips and add them to the cooler body, just inside the extended lip on each fin tip. This will keep the fan from directly contacting the fins and deadening any vibrations that may come from the fans.
Behind the motherboard I used the universal Intel back plate. This works for 775, 1155/1156, and 1366 just by inserting the studs into one of the three holes in each leg of the plate. At the end of the threaded studs is a large nut on the end that will grab inside of the back plate and keep them from spinning on you in the rest of the installation.
Once the plate and studs are in place, on the top you add the spacers over the studs, and with the holes in the top plate aligning to point at the CPU, you then screw down the top bars with the knurled nuts with Phillip's heads on the back.
After adding some thermal compound, with the fans off the cooler for access, all you have to do is align the plate on the base of the cooler with the studs on the top plates. With a Phillip's screw driver, you then mount the cooler to the motherboard.
You will know when the cooler is mounted correctly. Not only do the springs compress almost completely, but the threads end when the screw is completely tight, leaving no guess work in the thought of if it is on tight enough.
With the PH-TC12DX mounted to the motherboard, you can see there is a fair bit of room above these naked RAM sticks and the bottom of the fan. This will cause no issues with tall heat spreaders if you are just populating two slots.
If you plan to populate all four slots I suggest you look into low-profile memory or remove the spreaders (voiding the warranty and possibly killing the kits) as the fan does cause a bit of an issue with taller memory. It isn't impossible to populate, but the fan and the nubs that hold the wire clips will push the stick on an angle.
I figured I would end with this, a look at this tower cooler as it sits waiting to be installed on the X-Frame and tested. While it may encroach on the memory a bit, it does leave good access to the 8-pin EPS connection and surely is clear of the top slot on my GIGABYTE motherboard.
