[Elecraft] Quiet fans for K3

[Brendon Whateley]

So a question for the Elecraft team: Is there a reason you guys don't use
quieter fans straight from the factory.

I had a business partner who hated fan noise in computers, so would always
replace the stock fans with quieter ones (better blade profiles and lower
vibrations) and the cost never seemed to be much more than the stock ones.
Even though I thought the standard fans didn't make noise, the difference
was quite obvious when you ran a pair of machines, one upgraded, the other
not. Lots of people don't care, but some care a lot, if the price is
similar, why not start with the quietest ones?
