Hi Doug,
If noise is the issue you might want to search the archives. Some
time back a fellow posted information on a replacement Noctua fan that had more
CFM output but was quieter than the original per the specs.
So if replacement is required then possibly the replacement could
also be a upgrade.

Doug,
It is not really a problem to remove the fan.
Take the top cover off, remove the 4 screws holding the fan panel, unplug the
fans (noting which connector goes where), and you may want to remove the leads
to the circuit breaker.
Except for putting a new fan on the fan panel, that is all there is to it.
The lead length to the connector is different for each of the fans.

Dear OMs and Yls,
One of my K3 fans makes more noise than I care for whilst running just
65 Watts in CW mode. I wonder if there is an easy fix for the existing
fan. Maybe the only fix is a fan replacement? Secondly how problematic
is it to remove the fans? Does one need to rip out many components to get
to the fans. I know I could start pulling the radio apart but someone
else may have a suggestion. Yes I can read the assembly manual but perhaps
there is a shortcut. It may not be worth the effort or perhaps I best wait
till the magic time when I order the new Preamplifier board to further
upgrade the K3.
