Upper front fan at max rpm

Anyone know whats up? I can control the fan speed from software, amd all of my censors are fine. I’ve tried SMC and PRAM resets already. This started happening today. I did also reseat the fan assembly few times just to confirm it wasn’t just a bad connection.

3,1 Mac Pro

Answer this question I have this problem too

Is this a good question?

Probably a bad temperature sensor. If you can control the fan speed with applications like smcFanControl, TG Pro, or Macs Fan Control I personally wouldn’t bother trying to fix this.
