We create and update our compatibility lists with the utmost care. Unfortunately, motherboard manufacturers tend to change certain components and heatsinks without pointing it out by using corresponding revision names. If you run into problems while installing our coolers on one of the motherboards listed as being compatible, please don't hesitate to contact our support team at email@example.com.
Please also keep in mind that other components such as narrow or small cases as well as memory modules with special (higher) heat-spreaders can cause compatibility-issues.
For use in systems from Dell, HP or Lenovo, please note this FAQ.
Please refer to the following drawing for the exact measurements and clearance for RAM and motherboard heatsinks:
