On a NF4 board for the NF4 Chipset. Can I put a nothbridge block on it, the same way I had attatched onto my NF2 motherboard. My new motherboard is a DFI SLI-DR. It has the active cooling, just wondering if anyone knows if the northbridge blocks still fit. I should of wait, but I sold all my blocks before I recived my mobo. I knew the cpu wouldnt fit.
