It seems there are only two fan headers on 8300 motherboard one 4 pin for cpu the other 3 pin for back chassis fan. CPU PWM fan needs to be 4 pin, while chassis fan is constant speed thus 3 pin. It is standard not Dell proprietary, but running two fans off one header requires care not to draw too much current because the fan header has a max current rating.
Is there a splitter for the proprietary fan header so that I can run a front intake fan that'll be controlled by the motherboard? I see there is a place in the front vent area for a 92mm fan; would prefer using a splitter so motherboard can control temps/speed instead of just directly to PSU running one speed all the time. But assuming the fan header on the motherboard is proprietary and would need some kind of special splitter to work; or am I mistaken and regular one is ok (motherboard fan header is 3 pin right?)
XPS 8300, splitter for the proprietary fan header?
