NVidia’s Brian Burke brings us news of a new NVidia Driver that’s out, and while not WHQL certified this time, it does resolve the previous Fan issue found in 196.75 (supposedly, we haven’t tested it ourselves yet).  From their own release notes:

This is a WHQL-candidate driver for GeForce 6, 7, 8, 9, 100, 200, and 300-series desktop GPUs and ION desktop GPUs.

This driver resolves fan speed issues reported with version 196.75 drivers. NVIDIA asks that you remove 196.75 drivers and update to either 196.21 WHQL drivers or to this 197.13 WHQL-candidate driver.

If you currently have 196.75 installed, please first uninstall it before installing 197.13.
