Sure, I can assist with that. Please let me know if you need tips for connecting both the 4-pin Molex and the JST 2-pin connector to your motherboard.
The MOLEX links to a comparable male connector from your power supply. The others I haven’t noticed on a fan before seem unlikely. It might be an RGB connector of some kind. It could fit a specific RGB controller. Still, I’ve never seen a motherboard with these two connectors.
the query asks about the function of each pin in the JST connector. it mentions power and control aspects, noting that some JST connectors use two pins for batteries, three for DRGB or fan power and control. the person suggests avoiding using Molex for SATA conversion dongles to prevent issues with the PSU. they also point out that the distance from the fan to the frame indicates significant loss of signal, which could cause problems if used in front of a radiator. modern fans have very little gap, so they lose almost no signal. they searched for similar setups and found that most just connect directly to a Molex daisy chain, allowing full power regardless of adjustments.
The molex is intended for power, which is clear. I’m not sure why it also includes the 5V wire—perhaps it’s used to supply LEDs in the fan if it has any, rather than relying on 12V for the lights. I notice a single wire going to the two-pin connector. Some fans that use molex power connectors have a three-pin setup, but only the third position is active, providing RPM speed control for the motherboard or hub. It might also be the DATA wire for managing addressable RGB LEDs inside the fan. The ground for 5V addressable RGB is connected to voltage (5V), data, but if you use the molex’s ground and voltage together, you’re left with just the DATA wire—so it could fit into that two-pin connector. Maybe the plan is to connect both two-pin connectors to a fan hub, which then links to the motherboard via a proper three-pin connector (5V RGB / 12RGB), and the hub distributes the data to all fans.
I don’t believe there’s a dedicated hub causing the issue. I unplugged the fan after moving the PC case, but I couldn’t locate where to reattach it. It seems the fan doesn’t support RGB lighting, and my motherboard is a Gigabyte Z97. Likely an electrician modified it in some way.
The Molex connector is not secure and you should join the two JSTs to transfer power from Molex. However, the fan will run at maximum speed when your computer is active.
We’re linking these two components, but the cable only has one pin and two extra holes. Are you referring to the entire PC cabling setup? It looks like a cluttered mess inside a small enclosure. There’s a MOLEX input somewhere in the cable—its destination isn’t clear, but I can connect it there.
