Still problems there---please tell me the range you need

Not really--only seems to vary about 10c

Yes--it is a three-wire connector

Understood--as you can see, there are two speeds not showing--I would
guess that it "should" be one of those, but they do not have speed
outputs still. The Northbridge speed is around 2000 in the BIOS.
