Eddy,
Absolutely!
Exactly what I do on ALL boat anchot RX & TX AND the power supplys as
well.
I actually found a perfect fan to power from 12VDC that runs nice &
quiet & just moves just enogh air to work well.
Power Logic DC brushless fan, PL80D12M
connect BOTH the black & Yellow to -, and the red to +
Superb & quiet
73,
Lee

Hi Gang,
To those of you reading this who may still be in the "...contemplating"
stages
of somehow incorporating a cooling fan into their "C"-line rigs, allow
me to
share an experience that I just went through here this morning...
I am in the process (still!) of validating that my latest-and-greatest
"fix" to
the stability of my T-4X transmitter PTO is, indeed, still valid---and
so I had
the set on, warming-up in the basement, where I'd venture forth every
hour, or
so, to check the frequency. About a half hour ago, I noticed that the
top & side
of the T-4X enclosure was VERY hot around the final PA cage
inside---and so, for
giggles, I plugged-in the wall wart that powers the small cooling fan
that I had
mounted awhile ago atop the enclosure just above the final PA tubes...
After feeling the blast of VERY warm air being driven upward from the
rig by the
fan, I got distracted with something in the receiver, and so focused
upon that
for a few minutes---and ONLY for a few minutes! I then felt the sides &
top of
the T-4X, and lo & behold, even I was surprised to note that it had now
actually
become almost COOL to the touch!
My fan is a small one, & was "liberated" from an old computer: it runs
on 12
VDC. I installed a series-dropping resistor in the "B+" wall wart lead
to drop
the voltage down to 10 VDC---and to quiet the thing down to a whisper.
It blows
the hot air up OUT of the cage, rather than down into it. Two small
screws
secure it to the top enclosure (they fit right through the conveniently
pre-punched holes therein), and I used a plastic "chicken band" to
secure the
power lead from the wall wart onto the enclosure---a sort of "strain
relief", if
you will...
If heat is the #1 culprit contributing to shortened life spans of
electronics, a
cooling fan will surely go a long way to adding years to the life
expectancy of
your rig's critical components! It's a no-brainer, IMHO...
