[Novalug] FC6/Fan Speed

[Kevin Kitts]

I usually select quiet hard drives too - but bought this box off eBay - and
it came as is.

Incidentally, I'd forgotten, but on this shuttle computer the back of case
fan *is* the CPU fan - it is probably hard to envision that - you can google
for a picture of "Shuttle ICE" - but a heat sink is attached to the CPU -
and a series of pipes run from the heat sink to a case fan that directs the
hot air out the back of the case.

I found a highly reviewed/popular Zalman drop-in replacement for this fan at
one of the forums on www.sudhian.com - it's only $9.00 - I think I will give
it a try.

I may be straying off topic - but I recently had two computers that had
overheating problems - I think totally solved by just cleaning a heavy layer
of dust that had accumulated on the CPU Heat Sink. That reminds me... need
to pick up some canned air... could this conversation get any more "geek"...
;-)
