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.
