Radeon 4870 Fan Speed Revs Up at Startup / Shutdown -- Normal??? Tags: Radeon Shutdown Splash Screen Fan Speed Graphics Last response: January 26, 2009 5:49 AM in Graphics & Displays Share jmacfarlane September 13, 2008 12:59:31 PM 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!
