Hey guys I’m a little bit lost with the fan situation in my PC. I have 1 exhaust fan and 1 intake fan. So I decided to add a splitter so I can have 1 more exhaust fan but the issue is one fan is 4 pin and the other fan is 3 pin. Do I leave it on pwm or dc in the bios settings. Or should I not even use the splitter and just leave the 2 fan setup.
