Wow, I didnt notice that.
I wish it is 3% of gpu and not 48 % (!!)
I just bought a 1080 ftw second hand and I am very worried 
Although it has no major problem, I'm not sure to keep it because if it has weakened components, it does not live old, and for that price ... this is not what I ' hope !
I would see when I receive it.
What about EVGA costumer service with second hand?
The "3-4% of VRM IC's" statement relates only to the "black screen and fans 100%" symptom that some had with their 1080FTW cards. It should NOT be confused with the other discussions regarding overheating components (VRMS or otherwise).
First, check to see when your card was shipped from EVGA. Use the "Guest RMA" page on EVGA's website, plug in your serial number, and see when it was shipped. If it was shipped from EVGA after Sept-1-2016, then EVGA has stated that the "3-4% of VRM IC's / Black Screen / Fan 100%" issue does not apply.
Second, if your card was shipped from EVGA before Sept-1-2016, read through the LONG thread about the "black screen and fans 100%". There are several games mentioned that seem to trigger the problem pretty reliably for the cards which had it. If you can run those games for 1+ hour without problems, it is likely your card is not affected by the "black screen and fans 100%" issue.
As for warranty on a second-hand card, you should ask EVGA directly. They are GREAT about RMA/Replacements for the original purchaser, but I don't know if or how that warranty is transferred to a second owner (and it may also depend on the country in which it was purchased). I recommend you contact EVGA directly and ask if you have warranty coverage, in case you need it in future for any kind of issue.
