Today, NVIDIA posted new drivers that resolve customer reports of fan speed issues with 196.75 drivers.
Download the New 197.13 Drivers (Posted March 17, 2010):
Windows 7 and Windows Vista (32-bit)
Windows 7 and Windows Vista (64-bit)
NVIDIA apologises to our customers who installed the 196.75 driver and experienced quality issues. For the small number of customers who 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 NVIDIA customer who has questions about their board as a result of downloading 195.75 driver should contact their board supplier.
