    I've been messing with the Fan speed setting in the BIOS and can't see any difference between Automatics and Continuous. Anybody have an idea on what exactly they do?

    I believe that automatic is where the speed of the fan is determined by the heat whilst the continuous mode should mean that the fans are constantly running at a high speed.

    Well your guess makes sense, but the setting determines how the BIOS handles low fan speeds, and continuous handles the same as automatics. Couldn't see a temp difference either.

    IMHO "automatics" means that fan speeds are controlled mostly by monitoring hardware and partly by BIOS/OS whilst "continuously" means that the BIOS and OS controls the fan speeds. Maybe it can be interpreted that if a temperature is getting high a signal is raised to increase the fan speed whilst "continuously" could mean that the BIOS and OS are constantly monitoring the temperature to determine the fan speeds. This is something like a push and pull mechanism. This is however my interpretation.

    In another thread I mentioned that my machine completely shuts off when I run memtest86+ (during test4) if I set the fan speed to "automatics" and if I set it to "continuously" my system does not crash.

    I think I have noticed the difference:

    When set to "automatics" when my system goes from light load to heavy load the fan speed goes from slow to suddenly fast and when the heavy load goes back to light load the fan speeds go from fast to slow in one step.

    When set to "continuous" when my system goes from light load to heavy load the fan speed gradually (linear) goes from slow to fast and vice versa.

    I have noticed this difference when I close all my applications and when I run Enemy Territory Quake Wars.

    You will also notice a difference when you hit the "A" button next to the power button.
