You could try 2 x 12V fans in series to give a bigger cooling area but
smaller current; I did this once on a noise-critical application.
In terms of S units at the other end, turning down the power, say 25% makes
sense.

I run a 4" (120mm) computer case fan that the specs say draws all of .15
amps, 1.8 watts @ 12V, at full speed.
It probably doesn't need to turn that fast to adequately cool the heat
sink so the current draw could be much less.
.15A or less current draw for a fan is insignificant, IMO, compared to the
20A the rig draws on transmit.
If you want to save some battery turn the power down or decrease the duty
cycle.
