Last night, suddenly and without provocation, my MacBook started grinding and crackling something fierce, mid-Google Reader browse. I shut it down quickly, savored the adrenaline rush, and started it up again. It wound up with a loud whine that accelerated until... well, it slowly dropped to a low whir. And it continues to whir. But the computer runs (for now) as if there's nothing wrong. My guess is it's the fan. If so, though, what happened? It was so sudden. (And this is not the iMoo.) And does this require Apple service, or can I somehow fix this myself? Should I stop using the MacBook entirely in the meantime? Want to hear the racket?
