I dont think 96 is too high, but you do want the fans to go off again otherwise something isnt right. As long as your fan switch is a higher temperature switch than your thermostat, it should cool down to the fan switch point and they should go off.

Mine can get well over 100 when I've been booting it but when sitting at the lights the fans will go off once they've done their job.

I'm yet to block up my rad with a front mount though!
