For some reason, a couple of hours ago when I resumed my mac from sleep, the fan speed showed 000 rpm in smcFanControl and in the iStats widget. No matter if I changed the speed, it still stayed at 000 rpm. I didn't notice anything until the computer got up to 80c whilst watching a video on youtube. This problem is still present after a reboot, and I can't hear the fan either! I'm kinda bummed because I didn't take applecare when I bought this computer.
