I've searched and read through the -tech archives, and although CPU temps
have been discussed several times, I'm not seeing direct answers to the
questions I have.

This is a newish net6501-60 loaded with OpenBSD 5.3 "current" and a Crucial
M4 SSD. No hard drive, no other components in the standard case.


1) "sysctl hw.sensors" as root gives me 65-68C *at idle* as the CPU temp.
That seems quite high to me, given that the ambient temp in the room is
just 15C and Soren wrote last year to expect about 32 over ambient, so:
15C+32C = about 47C. But perhaps "hw.sensors" in OpenBSD is buggy for this
box and/or a compensation factor is needed to interpret its output? What
are others seeing for idle temps using OpenBSD when they run that command?

2) The manual says the fans are under control of the uManager, but provides
no other information. Are the temps corresponding to the "min RPM" and "max
RPM" values for the fans? Is the curve linear or logarithmic as temperature
rises?

3) Is there any difference between J12 and J13 as far as how uManager
addresses them and how they should be used?

Thanks
DR

PS I'm thinking of ordering a 30mm case fan but then putting a resistor on
the power lead it so it runs more slowly, just to keep the inside case temp
near ambient. That may be all I need for my application.
