Recently picked up a refurbished Y500 with SLI 650m's. I updated to Windows 8.1 right away and did the vBIOS update for SLI to work again. From what i remember, there was airflow coming out of the right side vent before I installed 8.1 and the vBIOS update but now there is no airflow and the card is reaching temps will into the 90's. I've reflashed the vBIOS, reinstalled the Nvidia drivers and reseated the Ultrabay slot with no luck. The Ultrabay GPU fan doesn't seem to start at POST and doesn't run when running Lenovo's Dust Remover Utility. Am I right to assume the second fan should be running at these times? Any other ideas to get this fan working is appreciated.. There is warranty on the laptop so not to worried.. just don't want the headache of bringing it in if it's an easy fix.
