I have found a computer repairshop that can do the change of the fan... But the problem is...
I know via predator sense , that it is the cpu fan (increasing and decreasing the speed of the cpu fan), but which fan do i replace? I dont have the schematics for the motherboard, so i cant see which contact the fans are plugged into the connectors on the motherboard. I know that the fans are cooling both cpu and gpu because of the cooling construction... 
It would be much easier to know instead of guessing and listen which fan that is bad ( not an visual, it is internal. And i dont want to order a second fan, just to replace both...
please help!

    Hello,
    The CPU fan is located on the left. JFAN2 is marked on the PCB (motherboard) and located between the two fans:

    I called Acer support  here in sweden and they could not help me. They dont have any manual or schematics for the motherboard of this computer... All i want to know : which fan is the cpu fan?  Your can control the fans speed via predator sense... So which contact on the motherboard control the cpu fan? 
    The model,  acer predator helios 300 ph317-52

    Hello,
    I finally found the information.
    1. The CPU fan is the plastic fan (plastic blades) connected to JFAN2.
    2. The GPU fan is the metal fan (metal blades) connected to JFAN1.

    Is it The first one or the second plug?
