I have a Lenovo M91p, and since the day I got it, the case fan has been extremely loud. While not consistent, it often times runs at (what seems like) 100%. This is extremely loud (I get a reading of around 75db a few inches from the case).
I installed Speedfan, but it doesn't recognize any case fans at all.
The Lenovo bios doesn't seem to have any fan control options. In fact, I can't find the word "fan" in any of the bios settings.
As a last resort, I replaced the fan, thinking that perhaps it was just a noisy fan, but the new fan has the same issue...basically blowing way too hard.
On the Lenovo board, this rear case fan is connected to the "system fan" slot.
Would connecting the fan directly to the power supply change its behavior?
Any suggestions would be appreciated.
