7v quick check

hogfather · 30 Jan 2006 at 19:22

Hi guys, just done a 7v mod on a 3 pin to 4 pin molex adapter, can you confirm this is correct before i power up? I'm not convinced it is!

damn, can't get a decent shot of it :|

To explain the layout, its Molex 1 (connects direct to PSU) ---- Molex 2 (extender, daisy chain molex) and off of molex 1 is 3 pin fan adapter.

SO,

Molex 1 (to psu) is

black (+black fan wire)
black
Red
Yellow

Connects straight to Molex 2, which is

Red
Black (wire which at one end has fan black wire, but not this end)
black
yellow

I know that's a head screw, but does anyone get what I mean? I've looked at numerous sites, but some have the red completely moved (at both ends) some don't. I don't wanna blow the psu!

I'll get a picture of mine now mate.

I've just done one and it's working.

P.S- Do you have one of those Y adaptor things?

EDIT: Here's the guide I followed. Link

If you get stuck with that give me a shout and I'll get a photo of mine.

Awesome mate, cheers! Its not a Y adapter as such, its a 3 pin to 4 pin adapter with the usual extra 4 pin attached too to let you daisy chain devices.

Just got a photo of it. Sorry about the quality. (Phone pic)

That's how I've done it. The one with the Molex>3pin is the 7V one and the other one is the 5V one.

cheers! So the one to the upper right is the 7v?

It looks like an unchanged molex though? yellow + fan cable at top, then black and fan cable directly below. Isn't that unchanged?

Just labeled the diagram for you. The bit with the red boxy-thing round it is the thing that changes the 3pin fan adapter to the molex one.

Fan connector.
7V Molex.
5V Molex

Thanks for that, really appreciate it.

How do I get the female pins out?! Sorry to sound like a noob

The male ones push out, but i can't switch the cables at the female end

I just put a small screw driver in the hole and pushed the little pin things flush with the rest of the metal connector.

A light helps quite a bit.
