I just have a question about Standby mode on an 11/34. I read it's
supposed to leave power applied to MOS, but do the fans and whatnot turn
off along with the CPU? Or are they supposed to stay on? My junk's in
a BA11-K box.

AFAIK it does nothing useful unless you have the battery backup 'brick'
and the battery unit. If you have those, it keeps the MOS memory powered
from that system. The BA11-K power supply can't
have the outputs
independantly controlled, so the Standby position turns everything
off
(fans, CPU, memory, the lot).
One problem if you do have the battery backup unit is that the fans will
stop when the backup unit is in operation (either due to mains failure or
because you've switched to Standby). This is probably not good for the
memory.
The 11/44 supply got it right. The standby postion on the key of that
machine keeps the memory and fans powered, just shuts down the CPU and
I/O supplies And if you have the battery backup unit, then the fans keep
running when the memory is powered from the battery. The downside is that
the 11/44 supply is _very_ complicated and hard to repair.
