It does so on the initial boot.

Maybe, and maybe I didn't mention it prior to this. Can I blame it on 
oldtimers? :(

It has a small sink that runs hot. No fan on it ATM. So yes, dead silent. 
I'll probably do it like the pi it will replace, I have a video card fan 
on it, very quiet. Due to the almost vanishingly short cable from a 
teeny breakout board on the pi's 40 pin gpio, the pi is upside down and 
the cable with the spi bus to the Mesa 7i90HD interface card is only 
about 3/4" long. It is after all running at 42 megabits one way, and 25 
for the readback channel, 32 bit packets at a time.

With only about 80 lbs of skin & bones left, COPD is taking her out 
eventually, the hugs are gentle and too far apart.
