NVIDIA 197.13 drivers resolve fan speed issue
NVIDIA has released updated drivers (version 197.13) that fix the fan issues plaguing the 196.75 drivers.
NVIDIA apologizes to any GeForce owners that installed the 196.75 driver and experienced quality issues. For the small number of customers that did experience problems, in almost every case reverting back to our 196.21 driver immediately resolved their issues. We continue to work closely with our add-in-card partners and PC manufacturers to help resolve any additional customer issues not solved by reverting to the earlier driver. Any GeForce owner who has questions about their board as a result of downloading the 195.75 drivers should contact their board supplier.
Customers that need help contacting their board supplier can get help from NVIDIA Customer Care.
