Yesterday my neighbor gave me a Dell XPS 600 with a dud PSU, and I am parting out what I can, and being Dell, its not too much

I have pulled out the fans but they have proprietary fan connectors on them, they are good fans, 2 of them are Delta fans and they look promising but is it possible to mod the connector to work with a regular fan connector?

Most of the fans are 4 pin, and does anyone have a clue of what color wire goes in which hole and is there a guide on the schematic of the fan connector?

Thanks! (BTW, my soldering skillz are proficient enough to tackle such a task tongue.gif)

Red is usually 12v and black is usually ground. If there is a yellow wire it is probably 5v. Those fans also push some serious air so I recommend a fan controller.
It would help if you posted the colors of the wires or maybe a picture.

Is it this fan?

Most common Dell fans use 5 pin 4 wire PWM:

Black=Ground
Red=12v
White=RPM
Blue=PWM

Simply cut off the Dell connector and splice to a 3 pin fan connector.
Connect to your PSU via 4 pin Molex or Fan Controller. Do not connect to your MB.

You know you are living in 2012 when... Every commercial on television has a web site at the bottom of the screen.

sorry to high jack, but was wondering if this could be done to the alienware liquid cooling. Here are some pictures of the pin that looks just like yours but all black. Its coming out of the alienware liquid cooling block. I have a corsair 1000w powersupply and asus rampage iii if that helps any. Thanks again in advance.

I have done this before with 2 Dell fans.
Well, those wires arnt colored.. so you would have to use the multimeter or something. OR you can use a 12v source and try each wire until it powers up...

My guess is that one wire is ground, one wire is RPM sense and the other is 12v.

Thanks for your help iCrap. How about the one that is connector and looped to the other side?

I looked it up on Wikipedia:
Quote:
Dell, Inc. proprietary
This connector is an expansion of a simple 3-pin female IC connector by adding two tabs to the middle of the connector on one side and a lock-tab on the other side. The size and spacing of the pin sockets is identical to a standard 3-pin female IC connector and 3-pin Molex connector. Some models have the wiring of the white wire (speed sensor) in the middle, whereas the standard 3-pin Molex requires the white wire as pin #3, thus compatibility issues may exist.

Old thread but related question. I have some dell fans, with the same clip as this forum has but four pin with the clip lock on it. What is that connector called? I was thinking of getting some of those connectors, then wiring up that connector so the pin outs of my new fans match what Dell is expecting, and then on the other side have the female/male whatever I need version of whatever fan I end up replacing my dell fans with. That way I don't have to physically do any cutting on the original fans. Guess long winded way of saying make an adapter. Want to have the same end on it the current fan does as that's what snaps into the power header in the Dell case. Not sure where I get those and the associated clips to solder to the wires.

Thanks.

JR
