I've never had coil whine out of an EVGA card - but my sample size is fairly small and all pretty recent.
On the other hand, it would have to be pretty loud for me to hear it over the FAN noise in my mining areas.
Its a funny thing. Some people hear it, some people don't.
I have yet to have a failure with any EVGA card I've worked with.
The build quality is stout, the coolers are VERY efficient and well made (not flimsy like ASUS), and I haven't seen any dead fans on em either (yet). When I compare the quality of several generations of my GTX cards to other makes; they are just better in many respects. EVGA cards also usually keep a higher resale value.
After the mess I had to deal with when using r9-280x cards from XFX; I will NEVER buy ANY of their products ever again. These cards never mined either. They were in rigs that did A/V work for a lighting/audio company I work for (concerts, business events, clubs, etc etc etc). We did a LOT of professional video mapping.
I remember what MSI and Gigabyte were before they are what they are today, so I am still weary about buying their products. They had an excessively high failure rates on their motherboards for many years. I know; because I worked for the company that processed/recycled all of their "crush" items (returns, warranties, mis-shipments, overstock, discontinued items, etc). Although it seems they have gotten their act together. So I always consider them based on others' reviews.
After buying my ASUS GTX980; Ill never buy their cards; the cooler is a joke. It works... but, its not "securely" attached to most models. Ive had to re-paste mine twice because I bumped the cooler enough and it rose it off the die; and temps were 5-10*c hotter after. Just 4 spring loaded screws holding ALL that weight. Insane.
And the new manufacturers.... Well; I have seen the engineering that goes into a LOT of the cheaply made electronics nowadays (things like the reviews from bigclivedotcom for a start)... and I am weary about complex electronic products for that reason considering most can't even make their own proper LED driver or power supply for their products.
Enough of the long winded blabbering; But hopefully it helps explain why I am partial to EVGA. Ive always been thinking Quality is more important than Price in my head.
