First, you probably shouldn't run more that 30 or 40 watts on PSK31, so
you really don't need the fan. You don't need power with PSK31.
I used an Omni V on PSK31 and (at least my Omni V) wasn't really
frequency stable enough until the rig had warmed up for an hour. While
most PSK31 software can adapt to the frequency drift, it's considered
bad practice to wander all over the band.
During the first hour, it would drift 10 Hz or so during the time I was
transmitting (maybe 1-2 minutes). After an hour, the frequency was
pretty stable.
