laptop fan speeds

[Mashari]

hi, i have Asus N550LF core i5 4200U, the laptop fan suddenly speeds up to 25500 RPM (according to HWMONITOR) After it cools down from playing a game like Tropico 5 !!!

while playing cpu temp reaches 68-70c, fan speed is 4400 RPM

how is that possible 25500 RPM !!! pic: http://

it could be a sensor error since the minimal on is 2500 rpm try this on to see http://www.hwinfo.com/download.php
