"Either way, we don’t recommend you tear off your cooler since it would likely void your warranty."
That is incorrect. You only lose the warranty if you break or damage the card by doing so. I would agree that end users shouldn't need to in a friggen $1K device, unless they want to, but saying you'd lose the warranty is misleading and a tad fearmonging.
Still, AMD better get some answers soon. If it is a problem with the cooler, they better start making good on users that went and supported them with the reference cards on day 1. As a side note: this is why I wait for AIB models (specially Sapphire) on the AMD camp: gives people more time to "field test them" and AIB models usually are a tad more refined, cooling-wise.
