laptop fan doesnt blow harder when hotter

[NL_Bumblebee]

yesterday i was watching netflix on my laptop ( ASUS K52JT with a i7 740qm cpu)  and all of a sudden the thing shutsdown like someone pulled the ac cord. i thought there was a stupid update wich restarted my laptop.

 

but after i turned it on and continued watching netflix it happend again after around 10 minutes and i noticed the air comming out the airvent was very hot and i checked the temps right after i turned it on and all 4 cores where on a 80 degrees celcius.

 

i also noticed the fan wasnt spinning hard , usally when it gets hotter i can hear the fan spinning harder then with its on low temps.

 

so my question is there a way i can manually set my fan to 100% to test if it still works.

 

Im also pretty sure the thermal paste is still good since i replaced that around 1-1.5 years ago.

 

thanks

I'm not 100% sure if it will work, but you can try to use SpeedFan to configure your fan curve or just to manually control the fan speed.

yeah i know that program, unfortnaly i dont think my laptop supports that that i can manually control my fan speed , because i dont see that option anywhere.

 

btw it says my fan speed is almost 4000rpm but i can barely hear it.
