Alienware 17 R2 loud fan

I've a problem I didn't have in the past. Meanwhile I did do SSD upgrade and Windows 10 upgrade.

Problem is that my fans always are loud. And no, it's not because of clogging, dirt or anything like that. I tried to apply all the standard solutions already. In fact, I can use hwinfo to decrease fan speed and the temperature won't increase or anything. I also tried each BIOS version which didn't help.
