No fan values with W83637HF

Fri Dec 10 14:40:10 CET 2004

Hello,

I'd like to thank you for the good work being done. But that's not the
main subject of this mail.

The mail subject is the (light) issue I have with W83637HF
sensors. Everything seems to be running fine but I have no value for
the fans. The fans (box and CPU) are correctly identified in the BIOS.

----------------

Here's what I get running the sensors command (everything was
configured by sensors-detect)

I run the kernel linux 2.6.8-1-686-smp as shipped by Debian, along
with sensors version 2.8.8 with libsensors version 2.8.8, as shipped
by Debian (sarge) too.

Any clues ? On another computer, with different hardware but working
with lm-sensors (it87), I notice that fan speed is shown only when it
reach some value; and I read stuff related to that in the docs. I
tried to do some checks about that running the CPU at 100% for a while
(I guess the box fan speed increased since the box temperature was
going down (5°C decrease) while the CPU temperature was increasing) 
but I'm not sure the test was really conclusive since I was not able
to make the CPU getting hotier than 57°C.
I also search on the web and found mails about the w83637hf support in
lm-sensors, derived from w83627 stuff: in these mails, apparently,
people were getting (more or less) accurate values for their fans
sensors.

Is there any other information I can provide? Is there anything I
should try? Or is it a known problem (I did not found relevant
information in
<http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/chips/w83627hf>
neither in
<http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/chips/w83781d>)

Thanks,
Regards,
