[QUOTE="pm-r, post: 1610732, member: 175845"] I'd agree Nick with your thoughts of the GPU being [I][B]shot[/B][/I]. Also, AFAIK, no [B]Fan Control[/B] app will allow any temp settings to be set lower than the Mac's OS X default settings, but I'm not sure that's true with [B]smcFanControl[/B], but regardless, an SMC reset would have reset any settings it might have made. I'll stick to my thought that at least of of the fans just isn't running. Maybe dead or partially disconnected somehow. And I don't know how else to check them other than with a visual inspection. ;) And I don't know if Apple Hardware Test would be of any help. [/QUOTE]
