Can't find fan distribution block powered by 3 pin fan connector

post #1 of 8

Thread Starter 
I'm looking for a fan distribution block that isn't powered by a four pin molex. I do realize there are 1:* splitters out there, but I'm looking for a cleaner solution.
I've already checked most of the outlets that I know of, and I also didn't find anything useful when doing a search here. I also realize it would be relatively easy to do my own with some PCB and connectors, but I prefer a ready made solution.

Examples of what I'm looking for are here (Except that all of these are powered by molex):
http://www.frozencpu.com/cat/l3/g47/...rts-Page1.html

Reason for use would be to put the upto 25 Gentle Typhoons I'll have between the three 3-pin fan channels on the Aquaero 5.

I understand the typical electrical limitations of these connectors, and how that makes my request an odd/difficult one. Perhaps it is more of an impossible one.

I guess I'll have to consider other options:

1. Terminal block.
2. Make a 4-pin Molex to 3-pin fan connector. Use one of the existing power blocks. Deal with the loss of the RPM wire.
3. Pull out bread board and make my own.
4. ???

Does anyone else have any other 'neat' ideas?

Maybe you could modify the molex from your PSU like I did in my pic here -




Instead of using the 4 way barrier strips like I did you could use this 8 way strip and branch your +12v and ground from the PSU's molex into 4 +12v and grounds connecting 6 fans to each +12v and ground.

If I can't find something that uses 3pin connectors, then something like this is exactly what I'll do. Thanks.

if you can find a 4 wire phone distro bar you could use it and just use 3 of the 4
might check home depote or lowes for that

you might have to use a punch down block

They make 3 Pin to Molex adaptors, though those are mostly for connecting a poweradjust 2 to a DDC.

I understand the typical electrical limitations of these connectors, and how that makes my request an odd/difficult one. Perhaps it is more of an impossible one.

4. ???

Does anyone else have any other 'neat' ideas?
