CPU Fan Is Very Loud

[Kenshin72]

My laptop's fan died completely so I ordered a new one, plugged it all in and it is extremely loud and the fan is spinning extremely fast. I reapplied thermal paste, compressed air cleaned the fan and the entire laptop. Wondering at this point if I should just RMA the fan.

Did you get one that is completely compatible?

i.e.
a) 4-pin PWM or 3-pin (same as before)
b) variable, with same RPM range

Since the fan is spinning, I'm wondering more if it's the WRONG fan?

Check model number compared to old one, but check my points above if different model (may work the same).

Its not the exact fan, but is the same size/shape, 4pin same as the old, same voltage.

Only place that had the fan were shady looking websites.

The VOLTAGE tells you nothing useful, most fans are similar voltage (12V desktop, 12V or 5V laptop but not sure). As I've said,

*fan most be a VARIABLE design (i.e. 500RPM to 1800RPM)

The noise also depends on the design and quality of the fan.
