Hey, I have 4 fans in my PC but the motherboard only has 2 fan headers, one for the CPU fan and one for the case fan. I purchased a splitter and have connected the cpu fan, and 2 extra fans to the splitter. However, now all 3 fans run at full speed (quite loud) and the white LED's in the 2 fans aren't on. Any ideas why this is and what I can do to fix it? The mobo is MSI B450M PRO-M2 and the 2 LED fans are three pin.
