Eric,
If you'll pardon a little self-promotion, you might consider using
FANticipator to control the fans in your KAP1500. It's free, runs local
or remote, and will perform those speed-changing tasks automatically for
you... including shutting the fans off completely when the amp returns
to ambient temperatures.

Subject: [Elecraft] KPA fans in digital modes
I, too, use FAN2 for both the KPA500 and KPA1500 in digital modes.
Both amps run considerably cooler and with less thermal variation.
It would be great if the PF1 or PF2 keys on the KPA1500 could be used
to toggle into a preset FAN2 (or choose your poison) when pounding away
on digital modes like MSK144 for meteor scatter on 6m. I don't know if
it would be possible to do something similar for one of the keys on the
KPA500--perhaps the AUX band switch? For both amps I switch back to
FAN NOR for casual CW use.
For all of you out there with even a 3el beam and 100w on 6m, please
try meteor scatter using MSK144--you can make contacts every day out to
1500km or more, even without a clear horizon. Schedules optional at
the Ping Jockey website. It's a blast!
