"Oh, brother. We can already tell this one's going to be a fun, enjoyable journey to follow. Shortly after Apple's 17-inch unibody MacBook Pro began making its way out to early adopters, small legions of owners have reported all sorts of bizarre graphical glitches. While we first assumed that it was NVIDIA's GeForce 9600M causing all the mayhem, further investigation has led us to believe that faulty fan controls could be the culprit. Granted, all of this is just speculatory at the moment, but it seems that some users have noticed that their fans aren't kicking into high gear when they should. 'Course, some folks have seen those RPMs spin up while the funky lines and psychedelic colors remain, so it's still hard to pinpoint a definite root cause. We're told that folks from NVIDIA and Apple are spending their weekends working to figure it out, but we can't help but be reminded of an eerily similar string of events with overheating MacBook Airs just last year. Hopefully a fix will be out soon; till then, just pretend those erratic colors are some new curative feature.Read - Fan grumblingRead - More discussions"^^<http://www.w3.org/2001/XMLSchema#string>
