Sapphire RX 470 4GB OC Reference cards overheating?

[couture]

1. Is anyone mining with rigs full of these cards? The single, centrifugal fan type?

2. Have you had any issues with overheating or with the cards dying and needing replacement?

3. Any remedies or solutions if the answer to 2. Was yes? I.e: auxiliary fans to aid cooling or lower the clock rates so they can chill out a bit etc?

Thanks

No problems with proper downvolt and clock tuning
