Compatibility and Installation

XIGMATEK Thor’s Hammer is designed to fit onto LGA775/1366 and Socket 754/939/AM2(+)/AM3 mainboards. In the latter case you should use the enclosed swing-clip that catches on to the hooks in the standard plastic socket frame:

As you understand, you won’t need to remove the mainboard from the system case. The cooler in this case may be installed in two different positions.

When using the Hammer on a contemporary Intel platform, things get a little more complicated, as you will need to remove the board from the system case. First you stick the backplate to the bottom of the mainboard PCB. It is the same backplate for both: LGA775 and LGA1366:



So, when you upgrade from LGA 775 to LGA1366, all you need to do is turn the backplate around. Then you fasten the steel retention brackets to the base with included screws:

And then simply install the cooler onto the CPU and tighten the spring screws to the backplate:

You can use a regular cross-head screwdriver for two of the four screws. The other two screws that get beneath the heatsink plates will need to be tightened using the enclosed little wrench. The retention is extremely secure and since the 775/1366 socket retention holes are symmetrical, you will be able to turn the cooler any way you like.

By the way, since we mentioned the cooler positioning on the PCB. The tests were performed with the cooler installed two different ways: with the airflow directed towards the back of the system case:


…and with the airflow directed towards the top of the system case:


The peak CPU temperature was constantly 2°C lower in the second case than in the first one. However, we only saw this difference when we used XIGMATEK Thor’s Hammer with only one fan. If there were two fans installed for air intake and exhaust, there was no efficiency difference between the cooler installations.
