(Is this the right place?) Is it possible to mod 3 pin fans to run off the same molex

post #1 of 15
Thread Starter 
I have 5 fans I want to run off the molex from my PSU, however I had to use one of my adapters that does this for another build.

So now I have 5 fans, 4 adaptors, and not enough reach on the 3 pin wire to reach the motherboard to use one of its headers.

Is there a way to mod it so I don't fry anything and use one connector for two fans?

Connector in question:

If you can solder, it would be simple to make a custom adapter.

As for hooking 5 fans to the motheboa4rd header, most motherboard headers are good up to 2 watts. Five fans, depending in which fans you have, could overtax the header.

Oh no sorry for the confusion.

I want to run all 5 off molex. The only reason the mobo header came up is because its going to be too far away to connect the one fan that won't have a molex adapter to it.

I have 4 molex adapters when I should have 5, I was wondering if I could just connect two fans to the same molex adapter via something like simply splicing the wires and connecting one fan to the other.

Or could I use a old molex plastic piece and mod the wiring into it and connect that to the end of the molex adapter.

(The adapter has one 3 pin plugin, another 3 pin for a header a 4 pin molex for the psu and another 4 pin molex to which can be plugged into another molex piece such as another adaptor or a molex to 6 pin/sata adapter or old 4 pin HHD.)

Sorry if this is really confusing, I don't know the lingo.

Ok thanks I'll create my own molex connector from the 3 pin via cutting it off then just use that on the female end of one the molex adapters I have. Heck if I did that I could just put it into the actual PSU molex string.

I think I'm confusing the issue.

ur not...BTW use a precision flat head to remove the mini pins from the 3pin/4pin connector if you wish to sleeve the cables.

Good luck...pm me if you need some pics or other advice

Thanks for the help, I'll make it pretty later lol right now I just want everything to work correctly.



Duct tape in place of electrical tape (cause we're out).

Talking it out on here helped me figure out I had spare molex connectors I could use without splicing into two sets of fan wires.
