Re: Fans With Controlers Connection Question
If you have a fan(s) with both a Molex and a single yellow 3 or 4-pin connector block, then it will only be powered through the Molex. The other connection is for your motherboard fan header, which allows your mainboard to monitor fan speeds.
Edit--- I may have been confusing... the single yellow port I was referring to will consist of a connector (usually white) and a single yellow wire coming from the fan. This monitors fan speed.
