I have a skytech gaming prebuilt pc (don’t ask why prebuilt, it was out of my control). I find the fans extremely loud and annoying.

I’m trying to figure out what each of the pins do so I can connect it to the case fan pins on the motherboard instead of wherever the prebuilt connected it. I tried searching online but I couldn’t find anything about what function each pin serves. I also had a multimeter and battery and I figured out that the rightmost pin is positive and the second rightmost pin is ground, but I have no idea what the other 3 pins do. The center pin I measured at 5 volts, but when I connected the fan and measured again, there was no potential difference.

Does anyone knows any information about this 5 pin connector or knows where I can find documentation/specification?

Also if there are any other ways to make the case fans not run at 100% power all the time, please let me know.

      I just looked at the post you linked and the connectors do look like dell connectors, but the wiring is different. The dell connectors have the ground and positive pins in the center, but the fans I have have them on the right.

      As of right now I’m not even sure if my fans have a PWM or sense pins. I forgot to write it in the post, but they have RGB support and I’m not sure if the other three pins are for controlling the lighting or controlling the fan.
