Dell Inspiron N5010 BIOS upgrade

[mrowcp]

Hello,
At the moment my N5010 ( i7, HD5650 ) is with A12 BIOS and the fan is very loud.When I was with A11 BIOS, this problem was missing.
Does anyone tried the new version А15?From the "Fixes and Enhancements" I read:

1. Improved the BIOS password protection function.

but there is nothing about fan loud

Just upgraded and A15 didn't fix the fan loud problem
