I need to disable the Chipset fan. I own the Gigabyte x570 Gaming X motherboard. The fan provides almost no cooling and is very loud. I slapped a second much better fan on top and is much better at cooling. But the old PCH fan still sometimes kicks on even through the temp is -20C now. I cannot disable the PCH fan within BIOS, official Gigabyte SIV software, or Speed Fan. Maybe I can stop the voltage to it? I know there are major ricks involved, but I'm willing to take them. How do I shut off the fan?
