Are you sure about the various RFACT values?  I'm getting some very
strange voltage readings from this device, as well as some odd fan
speeds.  Interestingly, most of the reported temperature values seem
reasonable, although there may be one entry missing (the BIOS reports
on seven temperatures, but envstat shows only six).

From dmesg we see:

...
wbsio0 at isa0 port 0x2e-0x2f: Nuvoton LPC Super I/O NCT6791D rev 0x03
...
lm0 at wbsio0 port 0x290-0x297
lm0: Using default temp sensors
lm0: Nuvoton NCT6791D Hardware monitor
...


And here is what envstat reports on my system:

According to the Motherboard/BIOS monitoring page,

	       CoreV  =   1.021V
	        3.3V  =   3.328V   You got this one right!
	          5V  =   5.040V   This might be VIN1?
	         12V  =  12.096V   And this might be VIN0?
	     DRAMV/AB =   1.199V
	     DRAMV/CD =   1.198V

	    MoBo Temp =      37C
	     CPU Temp =      44C
	PCIE16_1 Temp =      42C   (perhaps these are the Aux Temps?
	PCIE16_2 Temp =      41C   At least two out of three values
	PCIE16_3 Temp =      41C   are reasonable.)
	     VRM Temp =      47C
	     PCH Temp =      48C

	      CPU Fan = 1035 RPM   (1K, not 10K!)
	  CPU Opt Fan = 1363 RPM
	Chassis-1 Fan =  785 RPM

(It's not clear whether envstat's "System Fan" corresponds to the "CPU 
Opt Fan" or to "Chassis-1 Fan"; the BIOS reports three fan values but 
envstat only has two valid values.)
