NVIDIA is aware that some customers have reported fan speed issues after installing 196.75 drivers from NVIDIA's website. NVIDIA has removed these drivers and asked its partners to also remove the drivers. Any customers still using 196.75 drivers are asked to immediately discontinue use and either roll back to their previous driver or install newer drivers. Driver roll back help can be found here.
NVIDIA apologizes to our customers 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 NVIDIA customer who has questions about their board as a result of downloading 195.75 driver should contact their board supplier.
If you need help contacting your board supplier, please contact NVIDIA Customer Care.
