I just bought these fans https://www.amazon.com/ARCTIC-Standard-Cooler-Configuration-Possible/dp/B076BXLHWC i would like to know if i need to plug them in the motherboard even though you cant control them and they always run at the same speed. I have one (different model and old) that doesnt use pmw as well and it just needs to be connected to the power supply. Can you guys help me out? I need to know it because i have to check if i need to buy a splitter for the pins of the motherboard or not
