I'm not currently running pusher fans, though I've certainly thought about adding them - mostly for the 'cool' factor. BTW, I'd wire them on their own circuit - with their own dash switch.
Regardless, after experiencing a relay failure on my puller fans (along with a scary high coolant temperature!!), the fix included a circuit breaker as well as a pair of relays in parallel. Each of those relays is rated to handle the full load, but I now have redundancy should one of them ever fail. And yes, I realize that, given those relays are sharing the load Murphy's Law says they'll never fail. I'm okay with that.
