The Heat Sinks

   

The first thing that struck my mind when I saw the heat sinks was, "Hey, this looks a little like Dynatron's Microfin heat sinks!" Why did I think that?

Well, first and foremost, the fins have a rough side as well as a smooth side. Second, the shape of the fins were literally "cut out" by slicing away excess aluminium to form them. But then again, I recently visited their site and saw their microfins heat sinks, listed as the JAC series! Surprise, surprise! Are they the same coolers? But that won't be the topic of this review... so let's move on.

The most striking feature about the heat sinks is the shape of their fins. Both the NP80D and the NP60D feature the "curviest" fins I've ever seen!

Here, you can clearly see the rough surface of the fins.

Here, you can clearly see the smooth surface of the fins.

The rational behind this might be that by curving the fins, air molecules that are blown down vertically by the fan are more likely to come in contact with the surface of the fins. This, in return, creates a more efficient heat transfer process.

Just in case you are wondering how Bitspower manufactures the curvy fins and if any bending was involved, I queried Bitspower and here's what they have to say - "It was cut out directly into that shape from a single block of aluminum. That's its manufacturing process."
