It's All In The Fins!

The most important and significant feature of the DC1206BM-P625 is its dense set of fins - their Microfin technology. So, let's take a closer look at those fins.

Sorry about the blurry picture but I couldn't get a better camera. However, it's quite obvious that there are no joints or soldering between the fins and its base. That's because the whole heat sink was manufactured from a solid copper block!

The fins were carefully and intricately cut out from the block! Therefore, no thermal resistance exists between the base and the fins, ensuring that all the heat absorbed from the CPU die will dissipate through the fins.

Being made of copper, the entire cooler weighs about 437 grams! Remarkably, the heat sink is somewhat smaller than most of the other high performance coolers. It measures up at only 65 x 63 x 32.15 mm. However, the surface area of the heat sink is still very large due to the closely packed fins.

It should be noted that the fins actually have both a smooth side as well as a rough side. Because I don't have the correct tools, I could not remove the shroud to show the details to you. I'm not exactly sure why there's both a rough side as well as a smooth side. According to some, a rough surface creates more surface area. Well, what ever it is, this heat sink seems to take advantage of both the smooth side as well as the rough side. Damn my ignorance... <sigh...>.

Now, if I recall correctly from the DC1206BM Model O's review at FrostyTech, they complained about the "damn, it's easy to bend" shroud. And there's also a jaguar or something etched into the shroud, hinting that it was really manufactured by another company.

Well, on this newer model P of the DC1206BM series, I think Dynatron Corp has taken some pointers from these guys and improved the shroud design. It is now strong and solid. It no longer feels like it would bend easily. Kudos to them for improving the shroud!

Ah... let's take a look at the bottom. The bottom of the heat sink is very smooth. In fact, it's one of the smoothest bottom I've come across so far, at par with the Zalman CNPS3100 and CNPS5000-Plus.
