VF-900CU (3-pin vs. 2-pin help!)
Howdy,
Just installed the VF-900CU on my VGA card. Only problem is that my card has a 2-pin fan control input and my motherboards' only 3-pin fan control is already being used for the case fan.
Any advice on what to do? Right now I am using an older card while I figure out a remedy.
Many many thanks for any assistance.

You can splice the two pin connector off the old HSF and put that on the Zalman fan if you want. It'll run full speed then, but you could use RivaTuner or the like to slow it down.
The only wires you really need are the red and black ones. The white is the tach wire that sends the RPMs of the the fan. It's not really necessary unless you REALLY want to monitor it's speed. To me, I don't care what the RPMs are, as long as my temps are acceptable and I can't hear it, it's good to me.

^^ I did try to splice the wires (red and black). I used the 3-pin plug that comes back from the included Fan Controller (leaving the yellow wire not plugged into anything).
Didn't work.
Are you suggesting I should be splicing the wires that come directly from the Zalman itself?
Also, wouldn't leaving the threaded wires exposed be dangerous?
Thanks for all the replies.

Here's what I did to mine, in order to get the VF900 to plug into the VGA fan header. Didn't really like the Fan Mate 2 because well...I'm lazy and often don't feel like manually throttling the fan speed (that and an opposition to having things hanging out of my case). Not sure if this is what you need but hope it helps:
Info:
The VF900 has 3 wires: black, red and white. You don't really need the white wire. Connecting the cooler shouldn't cause any overloading issues...if you are concerned about that. I mean, all it is in theory is a fancy heatsink with a standard 12v fan inside (not an electrician or an engineer, don't take my word for it >_>).
Black = ground
Red = 12v
White = RPM
Items needed:
- A 2-pin fan connector (I just clipped one off of my old VGA fan, make sure to keep several inches of the wire to work with, don't clip it too close to the base)
- Electrical tape (the rubber black tape for wrapping around wires)
- (optional) Wire stripper
Instructions:
1. Clip the 3-pin fan connector off of your VF900
2. Strip approximately 1/2 inch of the rubber sheath off of the black and red wires sticking out of your VF900.
3. Strip approximately 1/2 inch of the rubber sheath off of the black and red wires sticking out of the 2-pin fan adapter.
4. Twist the black wire to the black wire
5. Twist the red wire to the red wire.
6. Seal the connections with electrical tape. Make sure none of the wire is exposed! (I also taped off the white wire for good measure /shrug)
7. Plug the 2-pin connector into your VGA fan header
Voila!

A simpler method is to gently prise the plastic housing from around the 2-pin connector on the gfx card (it simply pulls straight off, but be careful).
Then simply plug the 3-pin connector straight onto this making sure black goes to where the original black was and red to red. White (yellow in my case) goes to nothing. Keep the little platich holder safe in case you ever need to install the standard HSF for an RMA - it will simply slip back on again.

That's exactly what I did back when I did air cooling (except I threw out that plastic holder). It's low risk and should take around 1 minute to get your fan working. Simplest solution although need to be careful as it's less firm using two of the connectors without any support. If you still need to undervolt, I used this so I didn't have to use the bulky fanmate controller.scrandman wrote:A simpler method is to gently prise the plastic housing from around the 2-pin connector on the gfx card (it simply pulls straight off, but be careful).

ok really dumb questions from me, but please bear with me
i have the above inline resistor that came with a zalman case fan
i would like to undervolt my x1600 pro graphics card using the above, the card has a 3 pin out to the fan on the card
- can i put the resistor inline from the fan to grapics card?
the wires are not the same order when looking at the resistor cable and the fan cable on the graphics card
- can i swap them around? if so how do i remove the wires from the white plastic housing? they are pretty tight in the there and do not want shift!
thanks in advance
