Hi Jean,

Your instructions worked!

I'm assuming I have to load up fancontrol manually (via a script) each time, isaset instructions need to be 
repeated after each boot up, right? Maybe I'm missing something.

I was able to set up fancontrol via the pwmconfig and the fan slowed 
down. Hopefully, it will speed up when necessary.

The first and last isaset lines returned the following:
isaset -y -f 0x2e 0x55 -> Data mismatch, wrote 0x0a, read 0xff back.
isaset -y -f 0x2e 0xaa -> Data mismatch, wrote 0xaa, read 0xff back.

These mismatches, of course, didn't effect the end result. Maybe they 
indicate something that I'm obviously not aware of.

Your help with this issue is greatly appreciated. Thanks.
