Got confirmation from Thermalright that it fits the Gigabyte's funky heatpipe arrangement. Or so the email from "Bob" at the Thermalright support states.

GD - Will it fit a Gigabyte GA-P35-DQ6 with it's heatpipe arrangement?

Bob - Hi, Yes, it will. Thermalright Support, Bob

For information purposes really. lol. I love indepths.
