Summary0000002: speedfan dosnt work with shuttle xpc sb62g2
Descriptionfrom the mail:
i was just wondering if you will add support for Shuttle xpc sb62g2? i865g chipsett.
> the 5000 rpm chipsetfan is quite annoying :>

the problem is that speedfan will in 99.9% of the time report temp as -1 for
> all temps except hdd's. fans are detected as 0 rpm.
> tried with smartfan on and off in the bios also

ive been testing a bit now.
just tried to start speedfan the other day and it detected the correct sensors and i had no problems adjusting the cpufan. :D
but it does have problems adjusting the chipsetfan. if i set % to 2% its still on full rpm (5000). when i set it to 1% i drops to 0001301:0004300.. still noisy.
BUT i had to check if speedfan could adjust the third fanconnector, and so i turn off the shuttle and connect an intel fan to the third fanconnector and boot up.
i start speedfan but i detects only -1 on all temps. i close speedfan and restart it. it detects 0 sensors.
i restart speedfan again. 0 sensors..
restart again
and again
then it detects the hd's. and temps as 127 on all three of them. weird.
i wont detect the correct sensors. :(
so now i use smartfan in the bios again. it has no problem adjusting the intel fan at fanconnecter 3.
thought maybe this would help.

any new info ?

I can't understand which is the reason why SpeedFan sometimes is able to find sensors and some others not.
The question is: is there any way for you to be sure that SpeedFan will detect your sensors for sure? Which one?

its totally random when it finds the correct sensors.
just tried speedfan again now. it found only the hdd temps.
I/O properly initialized

End of detection

when i start speedfan the cpu fan will go to 100%. even though speedfan doesnt detect the fans or the tempsensor. it overrides the smartfan in the bios. i have to restart the shuttle for smartfan to work again. :|

So: if you just run MBM, everything shows up properly an works fine. If you run SF it looks like that, after detection at startup, the sensor chip disappears. Right?
Try to start SpeedFan with the /NOTIMER command line switch and try to send me a SEND REPORT.

Now, the final check is: try to run SpeedFan only with the following command line option:


yeah baby ;D it works! :D
tried to start speedfan several times now and it works fine every time :D great :)

So, the fix is to use the


command line switch.
There must be something that collides on the SMBus and never releases it. I'm afraid it's the SuperIO chip itself. Some kind of interrupt might have been enabled by the BIOS and SpeedFan, like almost every other hardware monitoring software out there, can't handle them.
Thank you for your reports and time :-)
