Comment 42 for bug 280805

It seems nVidia deliberately set the 177+ drivers to run the fans at full speed, avoiding the notorious potential overheating problems of this series of graphics cards. Updating to to the latest BIOS (on the D630, A12+) makes this "hack" go away, but makes still the fans run constantly at low speed (say, 25%). This decreases the odds of a hardware failure, in the worst case causing it to fail somewhere outside your warranty period. It also leaves you with additional noise and lower battery life.

I currently have a A13 BIOS (not to my doing); has anyone tried downgrading theirs to a version before the "Enhancement for thermal control" was introduced to the BIOS? Personally, I prefer having a low-noise laptop, with better battery life, even if I run a small risk of overheating. (With Dell replacing it in the next business day if anything happens.)
