Hello. I have a recently acquired H270F that I was building off for my son. I am down to only having the power supply, MB, and CPU installed. I can't get to bios and it doesn't run thru POST. RGB lights, keyboard, and all but 1 fan come on. The rear fan in port CHA FAN1 does not turn on. I tried the fan in another port and it works. Checked the pins and there is no power. My question is, will this one fan port not working prevent it from booting?
