AMD's HD6990 might be a frame rate-crunching monster of a card, but its dual cores are kept cool by the same old wee AMD Red reference design fan. That may be fine for a single card, but is really pushed trying to keep two serious graphics cores cool – especially when the card is being ridden hard by the polygon cowboys.

Although it may sound like a vacuum cleaner, that reference fan's cooling capabilities don't match up to the decibels. And you can stop sniggering at the back too, Nvidia's reference cooling fans are just as bad. Even though it's right at the top of the food chain, and out of a great many people's financial reach, the HD6990 has desperately been in need of some love from third party cooling ever since it was released.
