    How are you determining the airflow of the fan?



    I used predatorSense to increase the speed of the fan and you can literally feel air comin out of it


    I am still very much doubtful there is a way to reverse a single fan to exhaust from the bottom. Look at the design of your laptop, the intake sits directly below the fans. The fans only fit one way as they are side-by-side and connected directly to the heatsink. Even if it were possible to flip the fan around and have it blowing opposite the other fan, it would still exhaust from the back. I think you are simply feeling the residual airflow when the fan is at maximum RPM. This is nearly identical to the cooling solution on the Nitro 5, which intakes from the bottom and exhausts out the back.

    You mean it's taking air from bottom and blowing out from the back or it is taking air from the back ?

    Thank you for the information you gave, it cleared my mind 
    turns out I found my problem, it was the back side of the laptop with full of dust , stopping laptop to Blow air out
    I used my vacuum Cleaner to suck dust out and think what?
    it worked !!

    Thank you so much for helping me, even that Video posted by PredatorHelios500 was so funny
    thank you.
