currently trying new U3 since last week.
with the latest cgminer fork from bitmain's website it seems to work without zombie now.
But:
is there a way to have an U3 and U1 mining on the same Win7 machine? I know U1 is like a joke, but all this kinda below 1 TH is a game these days.

any way to monitor temp of u3 and adjust the very NOISY FAN?
Noise: ~25 DB at 25 °C ambient temperature
this here is never ever at 25 db (at 20 celsius room) more
like 60-70 db.
