Yes, I've ordered the long T30 bit you suggested. But I'm more wondering if the B11 fan bumps into that skinny (non-cpu) heat sink thingy just beyond the CPU socket (towards the back side of the motherboard)? I wasn't quite sure if you had actually installed a B11 on an X11SPH, but sounds like you have, which is awesome. I should be good-to-go. Thanks.
