"The actual heatsink is a beastly, but pretty cool looking piece of hardware, known as the flower cooler. This of course is because of the copper fins, spread in an array . It is an ingenious design because, since the fins are fully copper, we have a huge surface area of
copper which allows the heat to be released very quickly. The flower cooler is bigger than your average heatsink, and as you can see is far too big for a fan to be mounted directly on top as you would with a more conventional heatsink."
