I have a 212 Evo on my latest build and I have of course been noticing all the after market heat sinks as of late have been going a different route as opposed to the older ones. With my current setup on my old build with an old Scythe heat sink the fan has a huge rad located right on the processor itself with the fan blowing directly on the rad towards the CPU. Of course the newer ones have the huge rad with the fan blowing parallel to the CPU, not blowing directly in the direction of the CPU. I was wondering why the switch. I assume the latest setup for the heat sinks is best otherwise it wouldn't be so popular. What are the pros and cons of both ways?
