The i8k module itself doesn't interfere with the BIOS fan control.
It just adds some ioctl to allow fan control from user-space. The
real problem is that the BIOS fan control is broken, as everybody
who own an I8K knows very well. If you run i8kmon with the --noauto
option you will just see the temperature and fan status as managed
by the BIOS. The i8kmon does the same job as the BIOS but uses lower
thresholds. The only difference is is that my program works.

If it becomes red for a short time it may be that the fan is slow at
turning on. If the button stays red for long time it means that your fan
is broken or stuck. Try starting it manually with a bent paper clip and
see if the red disappears. This is explained in the i8kmon manpage.
