Clutch fan

Switched out my flex fan for a clutch fan this last week. I've had it out a few times and it seems to be running a tad warmer. Got back tonight after about 30 minute drive, after shutting car off (very important :( I grabbed fan and moved it back and forth. I thought once clutch got hot that it wouldn't have any (hardly any) movement. It might be fine, I'm just unfamiliar with clutch fans.
