Tim,

Would it not be easier (and more relevant) to use an off-the-shelf
temperature-based fan controller? You could additionally have the benefit
of
proportional speed control which would help keep the noise down.

Well, the long hot days are back on their way and once again I'll be
stressed about the drive temperatures in my NAS (Netgear SC101)  I have
seen
a mod to add a 90mm fan to the case - not elegant but should work ok and
will be almost silent - I'll get a decent fan and slow it down.  I was
wondering how easy (or otherwise) it would be to build a timer circuit so I
could only run the ran when the disk is running.  Both disks are powered
24/7 but only spin up when active - I simply havent the electronics nous to
figure out what the logic is that spins up the drive but was considering
something like a 555 timer triggered by the HDD LED on the front panel.
Does this idea have legs, or have I missed something?

TIA

Tim.
