I have a MSI GE72 2QC APACHe, Its about 1 to 2 years old, I noticed that my left fan was starting to making loud noise when idle like a blender then it would sound like it was scratching against the case, while its going at 3118 rpm at idle. I tried cleaning the fan but nothing works, they also say because of [strike]bio[/strike] BIOS and need a newer version but i heard its risky in doing so, so I don't know if i should just update my bios or buy a new fan and if so should i get the same model or try a different bland.
