I had to remove the front fan assembly on my MP 2008 to access the ODD SATA ports, and in the process the screw that secures it to the motherboard dropped into the processor area. I'm hesitant to remove the heatsinks , lest I damage the processors. What do you think the level of risk would be in this situation? Alternatively, how important is that screw or where could I get one? The fans seem to be operating fine without it, they're functioning and I can't hear any vibrations from misalignment - could it cause any problems down the line?
