I found the quote I was looking for.

RedJaron :
Considering what we've seen from Asus on their Polaris Strix cards and the poor VRAM and VRM cooling, I'm wary of recommending their cards this generation.
I swear, I'm not kidding, the review of the RX 470 must have been edited. Something was wiped out, I know I even made some comments on the matter that seem to be gone. Since Tomshardware is the only site with this thermal camera to measure this, I wouldn't be surprised if Asus asked them to remove the part about the memory running quite past its maximum rated temperature on the RX 470. I just know it was there.
And now it's gone. This isn't the first time I've seen stuff disappear from this site.
