Fan controller on Nvidia 9600GTX not working?

So i've had this card for about 2 years now, and i love it! It packs a pretty decent punch!
Last night i cleaned out the dust and took off the heatsink to put on new thermal paste, and now when i've got it all put back together the fan won't turn on. Here's the kicker though, the fan itself works fine (i've got a 9v battery on it right now so the card doesn't fry while i type this out). When i put a voltmeter on the two leads from the card itself, it reads nothing. Is there something wrong with the controller? Did i damage something when i had it out? Everything else seems to work just fine, so i'm really confused, and any advise is welcome!

    Is it a 9800GTX or a 9600GT? It the fan header on the card is bad oops I would recommend using one of your spare molex or sata power leads to power this instead of the 9 volt. Yellow is 12 volt read is 5 volt.. You can use the 12 and put fan controller on it to keep it from running max all the time..

  2. That's a really good idea while i figure out some other way to run it (this might be the day i upgrade to another card). Thank you Thently!

    I still wish i knew what i did! It seems so odd that everything else works fine but the fan...
  3. No problem it happens you might have knocked off a little resiter or something like that be glad that the only issue you have is a "fixable" one..

  5. well, everything looks fine, but those things are small, it's very possible. but this seems to do the trick! I did a few load tests and it's staying cool. Thanks again! :D

    Go to services and make sure Com+ Event System and System Event Notification are running. These were turned off on my machine by other tweaking software. After these were enabled then Nvidia Performance Device Rules worked fine with a step less fan control.
