Sorry for hijacking your thread, but do you (or does anyone) know why
the fan speed changes like this?

I've noticed on EX-series, the fans go from 'spinning at normal speed'
to 'spinning at high speed' on a regular schedule even when the
ambient temperature hasn't significantly changed and the box isn't
doing much in particular.

We've got some EX2200 switches in physical spaces where the jet
engine-like noise the EX4200 generates isn't desirable. Unfortunately
the EX2200s make quite a racket when their fans spin at high speed as
well.

Cheers,
Dale
