Gigabyte GTX680 Fans Not Working

[dark-hello2]

Like the title says, my 680 fans have ceased to function. Every last one, and I have three.

They all spin freely, so I don't think the bearings are shot, and a multimeter confirms that the four-pin connector on the board is fine. I don't have anywhere to plug in a 4 pin on my motherboard to test the fans themselves. I've used OC software (EVGA Precision 16X) to set the fan speed to 100%, yet they don't even budge. They don't start upon POST either.

Any thoughts fellas? I'm trying to put off an upgrade for just a little longer.

EDIT: The card I have can be found here http://www.gigabyte.com/products/product-page.aspx?pid=4178#ov

After about two hours of searching, I found a motherboard that would accept the 4-pin. I think there's something wrong with the fans. I just find it odd that all three of the fans are dead, and not just two or one. Fans usually don't do that sort of thing.

If anyone knows a good place for replacement parts or aftermarket cooling for GPUs, please point me in the right direction. Not looking for super expensive, but not looking for something that will break within the week either.
