The ground connector of the fan cable should align with the ground pin of the motherboard header. So if you plug in a fan with a specific function (cpu fan plugged into cpu fan header) you can know what what that fan is actually doing without hunting for the correct sensor setting. I've been trying to connect my fans to their headers. That leaves the Connect one fan to CPU Fan 1 and the other to CPU Fan 2 / OPT. By adding up the quantities of the system fan headers and the computer processing unit fan headers, you should be able to determine the overall number of fan headers. One big block of 3 at the front and 1 at the back. If you connect to a psu molex connector, the fans will always run at full speed. I am still confused as to the purpose of the radiator mounted fan headersif used such that the radiator fans are connected to the radiator mounted fan headers, which is then connected to the motherboard via the AIO pump connector to the cpu fan header, does that mean that all three (2 x radiator fans + 1 AIO pump) will turn at the same varying speed according to cpu temp? The fan is shown as N/A in BIOS. Most fans are 0. I guess, it happened because i fixed the fan first in place and then tried to fit the male header to the connector, because of lack of space the header inserts at an angle causing the pin to bend. On another board it says 2 chassis fan headers. Socket: This is where the CPU will plug in. It’s been a long time since we saw a controlled device wired this way, but someone mentioned that Gigabyte had such a header on its older motherboards. Our Guide will explain exactly how to set up your PC fans and add extra fans to your PC for the best cooling performance. But the point is there is only one port that has the RPM signal, since the motherboard would get confused if multiple RPM signals were combined, so you only connect one fan to a "primary" port which the system then sees only this fan's RPM, but if they're the same model fans, will be functionally the same as the others. Now these 2 fans in the front don't have the rgb or argb control wires, only the one on the back panel. Please consult your products manual. ARGB headers on a motherboard let you directly control ARGB devices.
