The Heat Sink And Fans, Detailed
This Hardware Isn't For The Faint Of Heart
As mentioned, this cooler sells as the EKL Peter in Germany and the Deepcool Dracula elsewhere; the two are identical except for their names. We’re using the EKL Peter 79XX Edition for this article.
The Peter is an imposing piece of hardware, monopolizing three slots for the heat sink and two slots for the fans. If that sounds like a ridiculous amount of space for a cooler, that’s because it is a ridiculous amount of space. The EKL Peter will have to prove that its performance is capable of living up to what its size seems to suggest.
On paper, at least, the Peter's specifications are impressive.

The EKL Peter 79XX Edition can accommodate up to four fans. We're only using two because that's already more than enough for our Radeon HD 7970 GHz Edition. A pair of Noiseblocker BlackSilentPro PL2 coolers spinning at 1400 RPM handle the job for us, yielding 96 m³/h of volume.
One big advantage these fans enjoy is that they run well at 5 and 7 V. Two of them are barely audible at 5 V. You could conceivably operate them at 12 V, but then they generate acoustics similar to one of AMD's add-in board partners leveraging an aftermarket cooling setup. Although we'd get much better cooling performance from our heat sink and fan combination, we'd really like to cut noise.

You can also buy a 900 RPM version of this fan if you want to get even more aggressive about noise, and don't care about overclocking as much. We chose this particular model for its versatility, since it allows us to go for performance or quiet operation without breaking the bank.
