I, to my annoyance, found that the Noctua C12P HSF, despite the fact it's listed on their site as compatible, will NOT fit in the Rampage Extreme board. The brackets which are positioned top and bottom of the CPU, the top bracket hits the 1R0 devices and will not fit around them. The bracket does touch the gray block devices and I can fit the screws in the holes, but I'm frigthened to tighten them up incase I crush a motherboard component.

Just curous, what HSFs are people using with this board?

Thanks.
