fancontrol wheezy Dell T7610

[Dan <ganchya@gmail.com>]

Hi,

I recently bought a workstation to do calculations. It has two Xeon
processors with 16 cores and 32 threads in total. I realized that the
temperature gets very high on high load typically 80C. That is way too
much. Then I changed the fan speed in the bios from auto to high. Now
temperatures are reasonable 45C, but it is very noise and it never
stops (even with no load) I have to reboot the computer to change the
fan speed..

I would like to use fancontrol but I  get:
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

It seems that lm-sensors do not read properly the fan. I get:

I edited /etc/default/grub and added
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_enforce_resources=lax"
as suggested in http://hydra.geht.net/tino/howto/linux/fixes/w83627hf/

But no success. I checked /proc/cmdline and the option
acpi_enforce_resources=lax has been taken by the kernel.

Any idea or suggestion?

Thanks a lot,
Dan
