if system running fancontrol is suspended and resumed, fancontrol

I'm afraid this is fixing the problem in the wrong place. The BIOS is
responsible for restoring the hardware settings at resume time. Failing
that, the kernel should do it.
So you should first look for a BIOS update, even though the chances
that it fixes this specific problem are rather low. Then you should
tell us which hwmon driver you are using, so that we can add proper
suspend/resume code to it.
hwmon_vid
Whatever it is, it is not hwmon_vid, sorry. hwmon_vid is just a small
module which translates VID data into voltages.
it87 then?
Yes, that would be it, if you have that module loaded. The driver does not
currently implement suspend/resume, so the problem is not surprising if your
configuration changes default settings (which appears to be the case).
