A fan blowing at the compressor won't do anything significant
(maybe a few tens of watts at best, when the thing is generating
several kW anyway).

I half expected someone to say something like that...

I *used* to think along similar lines but there's more to it than you
think.

I've tried it and it worked for me, I'd suggest the OP does the same.

If it makes a worthwhile improvement, the fans can be wired so they're
switched on with the compressor.

(Best try a fan on the suction side initially, an extra fan on the
discharge side might not improve things much further)

I can almost guess what you might say next =)
