    asus A15 FA506QM

    I have no idea but the NOTEBOOK turns off after a few minutes working, it heats up but never turns on the fans someone with any idea to try
    Notice that when you enter the BIOS it says that it is spinning CPU fan at 2300rpm but it is not actually doing anything neither fan rotates

    Update, with the help of an adjustable fountain place 2V@700mhA on the red and black wires and if the fans spin normally

      If with the external 2V the fan spins and the machine keeps running, then you need to check the fan power circuit. Measure the voltages at the connector pins.

        4pin connector in order from left to right (yellow/black/blue/red) Y=1v B=.30v R=5.1v I understand that blue should be an RPM sensor, I don't know if yellow should power 12V

        ok you just turn it on the fans do not turn, I imagine that when a threshold of temperatures pass they turn on but the temperatures rise a lot and the computer ends up shutting down because of this
        , at first I disabled many applications that were loaded at the beginning this helped but the persistent problem the machine continues to turn off clearly due to superheating

          You should have power, ground, RPM sensor and pwm to control fan rotation. See from the fan part number if you can identify its pinouts.

          When connecting the external power supply to the fan pins, what is the rpm measured by bios ?

            Thanks to those who were interested, I disassembled the heatsink again and perceived that on the side of the video chip it had not made contact, apparently the thermal pillows that I placed, Even though they were the thinnest they had, they were very thick to place on top of the vram, these models have a joint that is very similar to chewing gum, then I went on Reddit, a user gave me a clue that seemed absurd but even so I did I got a material that is very good so much that it went from 20fps to 120 and I held them
            Of course I will continue to test it on new equipment but I was surprised by the result


            If you want to know what I used just write to me I will gladly pass on the information Click image for larger version
