I've now got a Swiftech MCW30 on my DFI UT X58 Northbridge. None of the installations packs worked to my satisfaction. The closest was the 'MCW30 AMD PACK'. I had to replace the two 4-40x1 1/4" screws with a couple of 4-40x1 1/2" screws. That made the spring mount setup perfect to attach the chipset to my NB.
