SMBus is there, now what? (fan speed problem)

[Olivier Drouin]

Hi,
	It's hard to know which command should work on which hardware. 
	Here is the output of mbmon, and as expected:

	[root at red ~]# mbmon 
	No Hardware Monitor found!!
	InitMBInfo: Unknown error

	I read http://mojo.ru/us/GSoC2007.FreeBSD.cnst-sensors.proposal.html
	and it looks like this is what I need though I'm not sure. 
	It's not clear if this patch will allow me to *control* the fan
speed. 
	Right now it's full speed all the time and if I can slow them down I
would be happy.

	Can this patch be applied to 6.2? 
	I think this board is 2 years old, it should have been supported by
now, at least the fan speed should follow the
	temperature of the system
	Again it's an Intel server board se7230nh1-e (entry level server
hardware).

	Oli.

Afair healthd never really supported anything else than very old Winbond
monitors.
You can try the  GSoC2007: cnst-sensors.2007-08-20 patch which imports the
OpenBSD sensors framework and has great support for the most commonly two
modern chipsets used (it(4), lm(4)).
It's a quiet big modification though. See current at freebsd.org archives for
the announcement from Constantine A. Murenin on 2007/08/14.
If you have an ASUS chances are good that mbmon helps. I had more luck with
it instead of healthd.

Best regards,
