This GPU is a little over 4 yrs old now, but I may need to hold on to it some time longer, as I'm waiting to look at Vega and the 1080 Ti. I was really shocked when I saw one fan not spinning, because I can run Furmark burn-in at under 75c for 5 min, and the Bench test under 80c for 15 min. However for a while now, I've noticed severe texture artifacts happening at times.
Anyways, to my question, is it worth getting a new set of Dual-X fans. I've seen the original ones on eBay as cheap as $11.99, with free shipping. That's the two fan set and wiring harness, but no mounting screws. The only ones I could find that were actually claimed for the 7970 model were from China.
One of my concerns is I recently saw on a Linus Tech Tips video, Linus said that one cause of fan failure can be over-spinning them when blow cleaning, which can supposedly burn out the fan header. However this fan harness connects both fans to one 4-pin header.
I've heard various stories about what can cause fan damage via cleaning, some say blowing them reverse direction hurts the bearings. I'm not going to lie to you, I HAVE spun up these fans when blow cleaning, but I never felt it was a speed that exceeded their RPM rating, and since one is still working, it seems the header is fine.
So...
1. Is my header fine if one fan still works off it?
2. China (likely Hong Kong) is a reliable source for some things like Korean made monitors. Are they trustworthy for this type of item?
3. Has anyone replaced something like this before without taking off the shroud? I managed to get the 3 screws off easily enough when looking at the fan, but un-clipping the old wiring harness and clipping the new one back in might be tough with the slim space between the shroud and PCB.
For now I've just ramped up the fan profile to start at 60% at idle instead of 40%. Plus I've adjusted the clock speed switch back to the 950 MHz position, instead of the 1000 MHz OC position.
This is the seller and the item I referred to. Not a top rated one, but has very good feedback and has sold a lot of these.
