Looks like we are both 'right' - although in the spirit of friendly internet banter...I think I'm more right :)
from the X9SRL manual,
Page 1-5, "FANA Thermal fan header for I/O add-on cards"
Page 2-23, " Fan1~Fan4: System Fans Fan A: I/O Fan"
from the x10-slm+-F manual
Page 2-25 "E. FAN A (CPU Fan)
However from an engineering perspective, I'd suggest your manual is wrong as no engineer would put the CPU fan header at the other side of the motherboard. FAN4 is clearly ideally placed for an exhaust fan and it would make sense to tie that in with the CPU1/2/3 headers, not FANA.
EDIT: Out of curiosity I downloaded a number of manuals and checked them all. Its inconsistent at best in the x10 range. Either trust the manual or verify what happens when you stop the CPU if FAN A adjust itself when set to optimal. I'll verify mine for peace of mind when its apart again when I experiment with some fans that are coming in the next couple of days.
