Soon after coming to realisation that their 8800GT SC/KO/SSC cards are plagued with a fanspeed autosensor problem, EVGA have made a BIOS update available to fix the issue. They say that by flashing your card with this update, a temperature decrease of around 10c will be seen under load.
The BIOS update can be found here along with details on how to flash.
We have released a new BIOS's for the EVGA 8800GT's that makes some adjustments to the fanspeed autosensor.
Basically the fanspeed ramps up quicker, and more gradually as the temperature increases. This update can lower the GPU operating temperature by about 10c under load.
Also, all new EVGA shipping boards will have this change in place, we have this posted for those of you with existing cards. You can find this BIOS on the EVGA downloads page, or below.
This BIOS is for those who wish their fanspeed to spin up quicker, there are no other changes.
