I recently decided to go from the D975XBX to XBX2 and ran into a problem. Each board had the latest BIOS, Intel Desktop Control Center (IDCC) and Intel Desktop Utilities s(IDU) oftware. When I used the XBX, both IDCC and IDU gave me accurate idea of how fast my cooling fans going. The board found the fans (and the CPU fan) that were connected to the motherboard. When I swapped out the motherboard, everything went well until I checked the IDCC and IDU. The board only picked up the CPU fan. In fact the other three fans (connected to the Motherboard) didn't register or show that they were working. One of the fans also seemed to be barely running. When I trying to have the software redetect the fans, only the CPU fan was visible. The other three didn't even register even though they were running. When I put the XBX back in--everything went back to normal. The software registered the CPU fan and the other three without any problems. I don't know if it's the board or new BIOS. I had high hopes for this board.
