My 9600 GSO has been using this driver without issue and yes my fan is
spinning fine fold...@home 59C. Vista Home Premium X64.
NVIDIA has removed the latest ForceWare 196.75 from their servers
because this driver has an important bug: it prevents the fan from
spinning and caused a death of multiple graphics cards around the world.
G92-based graphics cards (GeForce 9800GT, 9800GTX and GTS 250) seem to
be very affected by this bug.
I currently use this driver on a EVGA GTX 295 / Win7 64-bit without issue.
So in case of doubt, NVIDIA recommend to use ForceWare 196.21. But this
driver has a bug and prevents the overclocking of GPU
So the recommended driver is the ForceWare 196.34.
