Hello.
I noticed my fan speed is a litte high.
I did a test to see what happens, and the asus ia extreme fan is giving me this results...

As you see the pwm/rpm ratio is a little weird.
The fan starts to spin very fast too soon :S only at 30$ pwm its at 900rpm!!

I was searching some reviews and people is not having that problem.

Example:

As you can see, the fan at 30% is almost at idle rpm!

Whats happening, is this normal or my fan is faulty?

Thnak you.
 
Solution
What's there to say ? Each fan has some minimum voltage to start turning. that one is probably somewhere about 7 - 9v starting voltage. Ones with ~6v starting voltage can have higher min-max span and flatter curve.
