Lots of reasons why that won't work, but ultimately I would have replaced the fan anyway. The bearings are just too noisy and the fan design is not optimal for rads.
The LNA adapter is actually working much better than I thought. It is much quieter than stock, and still allows the fan to ramp up when connected to the graphics card header. However, it still idles too high, which I don't like. The ULNA adaptor gives me the idle I want, but load temperatures go beyond 74C with no sign of leveling off. At that point the blower fan got too loud and the card was starting to throttle a good bit, so I had to put the LNA adaptor back in.
I'm not too concerned about load noise as long as it's quieter than my speakers. The idle speeds are what's really important to me because I want a silent computer when idling.
The best way to handle this is to have the fans I ordered paired together and controlled by the gpu. We'll see next week if that will work out the way I'm hoping. The SilentWings 3 is one of the best noise optimized radiator fans out there. I just hope that the gpu will give the fans a low enough voltage so that they're silent when idle. Since they're going to be run in p/p, I should still have pretty good thermals under load, well better than a single fan at a similar rpm. We'll see
