HD7850 Fan Only Spins at 90%+ Speed

Hello there, i have an HD7850 which lately started doing this:
The fan is on auto and it doesn't spin, the latest "radeon settings" says speed 20%, but it doesn't move.

The temperature raises, the speed shows 35%, but fan is OFF

Temp keeps going up over time, radeon settings reports fan speed 50%...60%....70%...80% Yet the fan doesn't move at all.

 

Only when the speed shows "90%" the fan start spinning at full speed.

 

Setting fan to manual does the same.

Any value between 0% and 89% = OFF.

Any value between 90% and 100% = FULL SPEED

 

So basically my fan became binary..
