With a customized LGA 775 adapter kit, XP-120 is designed to fit all socket T (LGA775) motherboard. So far, we have not found any board that is not compatible with XP-120. If you've found any, we would appreciate if you could report them to here.

* All ECS socket 775 motherbaords require a bigger case (at least 25mm from motherboard edge to power supply unit) to accomodate XP-120.
** The screws came with the LGA775 RM package are too short when it is mounted on an Asus Stack Cool motherboard. The screws need to be about 1/8" or 3mm longer. Users reported that these screws are available at their local hardware store.

*** Large fan bearing heatsinks (80-92-120mm) can encounter problems with motherboards with sockets close to the edge of the motherboard and some cases with power supply brackets. Another potential problem with these types of motherboards can be large fans mounted in the bottom of the power supply and without the fan drills recessed.

**** To install a XP-120 onto Abit AG8 alike motherboard, you need to turn the NB cooler 180 degree (having the fan side face PCI slots) to give room to the heatsink.

* Tilting capacitors may damage motherboards. Users do this at their own risk.

** Unlike other mobo makers, Gigabyte uses a customized plastic motherboard backplate for its K8 motherboards, which is not compatible with XP-120 K8 retention bracket. Users need to remove it and replace it with a standard metal backplate before installation of Thermalright XP series heatsink. For more information regarding AMD K8 backplate please see Athlon64 processor thermal design guide (Fig. 5 & 6).

****As in the case for Gigabyte motherboards, Asrock also uses push-pins to put in place the K8 RM on the motherboard which is different from most of K8 motherboards in the market that use screws to fix the RM (through the motherboard onto a backplate on the back of motherboard.) Thermalright XP-120/-90 K8 RM (for use with heatsink for K8 platform only) is designed to replace those push-pins with screws.

*****The overhanging fins from the XP-120 will slightly come in contact with motherboard’s chipset & North Bridge heatsink near the I/O ports. This will not affect performance of both heatsinks.

Since the Asrock (and Gigabyte) K8 boards use push-pin type RM's, there is no backplate in the back of motherboard to support Thermalright’s customized RM. You will need to purchase separately a metal K8 backplate.
