I recently got a tuf b450m-plus gaming motherboard but when I connect the fan splitter only one of my case fans work. I tested the fan header with only one fan and it worked fine. Is it because I have the fans set to max instead of low? I will test the fan splitter on low but does anyone else have any other suggestions? I have at least 7 fans including the CPU and I can only use 3 as of right now.
