I was trying to use the fan header to control the fans on my radiator so the card controlled the cooling. Once you add a fan you can manually control it from the front of the GUI but if you flip to the fan curve screen it crashes out. it also crashes out for no apparent reason with out flipping to the page.
 
I tried reinstalling fresh after a clean sweep.
I also tried a different fan with the same results.
I did not reinstall the drivers, while it is possible i kinda doubt it since this is EVGA specific app that controls it. 
 
Removing the fan removes the issues and everything works perfect with out it. 
The fan is .3 amps the other fan i tested was .18amp
 
I currently just have the fans attached to the motherboard and every thing works fine there, i would rather it adjust by the GPU temps than the CPU temps.
 
Hopefully this is just a bug that will get squished eventually.

Yes. Previous version as well. I didnt know there was an update, but that was the first thing I checked on the old version.

The update has a new bios flash BTW. I am not sure what it fixes. Need to see if I can look it up.
