Fan wires - Excalibur - 23-10-2024
Went to replace front fan because it was noisy. Got it out only to discover it has extra wiring. Some go up to the switch area of front. Have refitted original fan to study and post this thread.
Replacement to left.
Please advise. Thanks

only thing I can think of is maybe it is for case lighting or a seperate speed controller unit on the PC... does it light up when on and/or do you have any kind of a led light or speed control on it?
you might have to trace that wire and see where it goes, you'll need to be able to detach it when you replace anyway - it's the silver/clear plastic wire ribbon going up towards the switch area?
The modern fans and motherboards have speed control built so I find speed controllers a bit unnecessary these days.
pinouts of the standard fans

seems to describe but would make sense if the silver/clear cable was the one with the mobo fan connector and the black/red was heading elsewhere, being power for an LED

LED is exactly what it is. Never knew it was there. Simple solution then. Thanks.
