I have a LENOVO IDEAPAD 310-15ABR (mb CG516 NM-A741 Rev 1.0). Replaced kbc and pmic an reflashed bios and EC bios. Everything works fine except for the fact that the fan starts slow and then approaching booting it goes to almost full speed and stays there. This fan has 5 wires and I've observed that if i get my hand progressively closer to said fan, it speeds even more, and the increase in speed is proportional to how close my hand is (mobo and fan on my workbench outside the rest of the laptop).
Used an oscilloscope and i can see the speed increasing there.
Using the scope I can see...
