I will be getting dual 4870X2 video cards in CFX, but the only problem is that the ICH9R southbridge is behind one of the PCI-E x16 slots, and with two video cards in CFX, the Thermalright HR-05 IFX that I currently have on it will not fit, nor will the HR-05 IFX SLI version.

So I want to get a low profile heatsink to use instead. I am looking at the Enzotech CNB-S1L:

Does anybody know if it will fit on the ICH9R, and if it does, will it allow for a second video card, or is it still too tall?
