CoolKnight:

In case you don't already know.... Macs do not use a BIOS.

Fans in a Mac are controlled by thermal heat sensors not a BIOS (which a Mac doesn't have anyway). The thermal sensors work regardless of which OS is running at the time - Windows or OS X.

The problem is that Windows games really tax the CPU and GPU causing heat to build up. Generally that's not a problem since the machine will shut down if it overheats. However, most folks do not like to hear their fans screaming at a high RPM when gaming even though that's normal.
And there are ways in Windows to control the CPU to cut down heat build up.

Regards.
