[Elecraft] Quieter fans on the K3 ?

[Clay Autery]

It would appear you made a good choice in fan selection....  FYI, I use
sorbothane for isolators and other damping needs.  Works great.  Noise
reduction depends on making sure to interrupt the connection between the
fan body and the mounting point in the case.... to include not letting
the same fastener touch both the solid fan chassis and the radio
chassis, etc. Next is to prevent airflow short circuits... et al.

The additional 10mm of case thickness doesn't interfere with anything?
