With the latest BIOS version (and without running a health driver), the hardware will start the fans at low speed and will switch them to high speed when a certain temperature (e.g. "temp-caution") is reached. The fans will then run at full speed until the server is rebooted. If the temperature reaches an even higher trip point (e.g. "temp-deadly") the server will automatically power off (without a graceful shutdown). There's no reason to use an older BIOS version. The latest version will start the fans at a low speed instead of starting them at a high speed. Thus, if operating in a cool environment, you'll have less noise. FWIW, some of the benefits of running a health driver (on a supported OS) are: - fans will gradually ramp up in speed instead of going directly from slow to fast. - a graceful OS shutdown can occur instead of the abrupt power off when the system overheats.
