My Radeon 4870's fan revs up to max speed for a few seconds when I'm starting up (just before I get my MB splash screen) and shutting down -- does this happen to anyone else? Wondering if it's normal or if there's some issue with mine perhaps. . .

Thanks!

my 4850 does the same thing. don't worry, there's nothing wrong with your card :)

Mine does the same thing. Periodically it will also if it gets too hot.

Its fine it does it at start up clear any dust that may have settled on the fan and at shutdown for the same reason and to boost the cooling of the chip before it cuts off and lets it self cool.
