i have a small 92mm fan with 3 wires attached to a 3 pin female connector (1 yellow, 1 red, 1 black) how would i rearrange em to run at 7 volts?

thanks!!

You don't on a 3 pin header. On that the red is +12V the black is ground anf the yellow is tach. lead.

You'd hve to get a 3-pin to molex converter and hook the black wire for the fan to the red wire on the molex.

+12V minus +5V equals 7V

hm thanks for the pictures and explainations but just to make sure heres how it looks for far:

fans black wire -> 4pin molex's black wire

fans red wire -> 4pin molex's yellow wire

so to make this 7 volt work:

fans black wire -> 4pin molex's red wire

fans red wire -> 4pin molex's yellow wire (same)

is that correct? thanks for the help just making sure, dont want to blow anything up lolz

hmm also how should i reconnect the wires should i just strip the outer rubber skin then reconnect and patch it up with electricity tape?

thanks
