Question about ASUS Rog G20ci-Ch019t

Hi guys! I bought this computer for 1599.- few days ago because I know Asus ROG G20 models are reliable for the price. I already have 3 of them. However the Asus ROG G20CI comes with fan speed issue which goes around 4000 round per minute when reaching 75-79 C°. On Asus ROG forum people complained about this issue and none found a solution and returned the computer for vain repair... I decided to make a BIOS Update and... It's magic! The fan goes around 3000 RPM and makes less noises at 79C°.
