I know this fan works, i plugged it into a plug on the mother board and it doesn't stay running it only spins a little at first when i turn on the computer. I can't figure out how to get it to stay running i've searched bios and the closest thing i find about a fan is the rpm of the cpu fan. I'm trying to add another fan to my case and i already have one for the psu. This fan only has red and black wires no yellow ones i'm pretty sure that wouldn't stop if from running so i'm pretty confused.
