4 Pin to 3 Pin Converter ?
Is there a cable that converts a 4 pin fan connector to a 3 pin ?
If so, does anyone know where to get them in the UK ?

Just a few points to note.. If your fan has a four pin connector on it then it may require more current than can be provided by a three pin motherboard connector. This sometimes happens on 120mm fans.
The second issue is speed sense.. the four pin connector doesn;t have it and by adding an adaptor you won;t magically have speed sensing. Sorry if this is obvious, but some people don't get this point.
HAving said that.. I'm not sure the ZM-MC1 is exactly what you're looking for - that'll let you plug 3pin fans into a 4pin power cable, not 4pin fan into a 3pin mobo connector.
As to sources of the cable.. dunno, sorry
Best bet is somewhere like Maplin but I only found A00BF and A45AK, which are equivalent to the ZM-MC1.
If you don;t find it elsewhere you could alsway hack one up - all the bits are available from Maplins.

have you tried directron? i haven't checked if they ship outside of US and they are somewhat more expensive than SVC, but they are another source:marc999 wrote:I've been looking for one of these for awhile, and in a previous thread someone mentioned that SVC cable. Unfortunately, last I checked, they didn't ship outside of the US.

This shouldnt be a problem as I wont be plugging it into the motherboard. The problem is I have got 2 120mm fans with 4 pin connectors but I have a fan controller in a 5.25 bay which connects the fans using a 3 pin plug. This controller then plugs into the PSU so power shouldnt be an issue.DonP wrote:Just a few points to note..

The issue is finding a way of plugging the fans into it.
Any ideas anyone.
tridion - Is thiswhat you are after? If not check these out as well just in case.....

[quote="marc999"]However, they only have a 3->4 power adaptor, whereas I need a 4->3.[/quote]
good point. you are trying to go from 3 pin fan controller to a 4 pin fan, right? now that i think of it, i have a similar problem, mating a 4-pin fan to a 3 pin fanmate. i had punted on it for a while, because i was hoping to batch a whole bunch of changes to the system all at once. now it seems that a simple solution i was planning on will not be so simple. please post here if you find an adequate solution!

Yes, you are correct. I'm going from a 4 pin terminated fan to one of the 5V connections on a Zalman Multi-Connector (ZM-MC1). I could always rewire the 4 pin fan to line up with the 5V pins on the power supply plug but that's a REAL pain in the ass and then if you want to switch to 12V then you have to rewire your 4 pin fan all over again. Not fun.you are trying to go from 3 pin fan controller to a 4 pin fan, right

returning to a dormant thread, i just did exactly that: rewired a 4 pin fan from 12V to 5V. i took the easiest route: took a spare 4 pin Y-extender cable (something like this http://store.yahoo.com/directron/cbl-y.html), cut the 5V and 12V lines, wrapped insulation around the dangling 12V line, connected the 5 V line to the wire going to the 5V pin and that's it. if i need to go back to 12V, i will take the extender out.marc999 wrote:grandpa_boris wrote,Yes, you are correct.

These aren't actual cable adaptors, just the actual pin heads:

These are Canadian online stores by the way.
Both of these are actually for panaflo's.
Vibe Computers sell them with just the bare wire, and you buy the '3-pin header kit' and attach it by yourself.
BigfootComputers one is just wire with the 3-pin molex already attached i think.
In both cases, I think it wouldn't be very hard to attach them to current fans. Unfortunately you'll have to cut off the 4-pin molex.
