    I have bought some 140mm fans and on the fan box the's voltage range (V DC) there is 5-12

    I have to mount on 3 (at least ) motherboards desktop

    I can't find any information on the motherboard specs , the only information is related of the CPU fan (supprot max 1A(12W) fan power)

    I want to connect 2 fans at the motherboard (4 pins) but there is nothing about fan power support , and I don't want to damage the motherboard

    may I know if there is a standard voltage for the fan motherboards ?

    and may I ask what should I do to avoid to damage the motherboard?

    on a computer there are 2 fans (3 pin) connected to the motherboard with 4 pin
