Prolimatech Panther Review @ OCC
 

With the heat sink out of the box, we will see the four heat pipes – uniquely, they are twisted together, holding up the mesmerizing fins. From the front and the back, you will really see four pipes extending to the top on each side (8 total). Similar to the Megahalems, the tips poke out above the top fin. From the sides, you will see that the pipes line up perfectly and start to get a perspective of how this is going to fit in your case. It's pretty tall, but not very wide – at least without a fan attached.
