    Lenovo T450 fixing

    Hello,
    I bought a faulty Lenovo ThinkPad T450.
    I would like to fix it to a desktop pc.
    No heatsink and no fan on the motherboard.
    When I start it it shows "fan error" and turn it off itself.
    I have a Chromebook HP 14-q011sa heatsink and fan.
    Problem is the fan plug on the motherboard have 5 pins.
    My fan have 4 pins.
    It spinning, but still "fan error".
    I need something more to realize it is there.
    Semantic, and how I pug the fan :images are attached.

    Could you help me please how can I use this fan?
