Freeing up HP is negligible for a couple of reasons:
1) Your stock fan really doesn't drain much of any HP.
2) By switching to electric fans there's a bigger drain on the Alternator, therefore making the internal generator harder to turn, and draining HP there. I'm not joking either, I know it sounds stupid, but the more energy being drained, the harder it is to turn. Thank you high-school physics.
