Since our last encounter with a Dynatron cooler, we were quite pleased with the build and performance of their units. They have incorporated Micro Fin technology in their units, which is basically the slicing of fins in one block of aluminum or copper. No fins are soldered, so expect a good transfer of heat from the base through the fins. We will take a look at their aluminum offering, the DC1206BM-L model. Yes, the model numbers are confusing as heck and I wished they would shorten it but what can you do right? Onward we go...
The cooler came in a pretty plain box from Ralph over at E-Compuvision. What was interesting, is that the bottom of the unit had a gray plastic cover to protect it. Never really seen one of these on a unit before, surprising to see it on such a light heatsink.
This Dynatron unit comes with smaller blue Top Motor fan, rated at 5300rpms and 24.4CFMs. It is recommended up to 1.7Ghz for AMDs and 1.26 for Intels. There is an option to add on a more powerful fan, so it is customizable to whatever suits your needs. I do like the Blue Top Motor fan, it is definitely quieter than any of the high powered fans we use around here.
The clip design does lack a bit in the usability department. You're going to need a small flat head screw driver to get this one on your socket tabs. Once on, it is very rigid and keeps the heatsink on top of the CPU very firm.
The above shot shows the Micro Fins covered by a shroud. The shroud is important due to the fact that these fins are very thin and are prone to bending. One of the beauties of this fin technology is that the fins are not attached after the base is molded. Take a close look and you'll notice the fins are connected directly to the base. I seem to stress this a lot, but this is one sweet way of making a heatsink.
The bottom of the unit comes with a square piece of pre-applied thermal grease. Not a pad, but grease. Only bad part is, if you mess up your installation the first time around, you're out of grease. Then again, I'm sure you can muster up a few ounces of it to put on your CPU core.
You didn't think we'll let that white paste slip by us did you? Off it went and on came the ASII. Here are some temperatures for your viewing pleasure. Please note, this is with the Blue fan that came with the unit. Your results will vary depending on what fan you decide to go with.
Our trusty old test rig is as follows:
IWill KK266 Socket A Motherboard
AMD Thunderbird 800Mhz CPU
Crucial PC133 CL2 Ram, 128MB
The test will consist of an idle temperature check and a full load temperature check. The full load will be accomplished by using the RC5 program and running 3DMark 2001 for 30 minutes. Arctic Silver II Thermal Paste used without a doubt.
Here are some results:

Not exactly the bone crushing performance you'd expect from the same company that brought you the BM0 copper version. But again, the default fan that comes with the unit is a 24.4CFM model. Upgrading that will most likely lower the temperatures. We will not be removing the unit and replacing it with one of our own, if it comes stock like it is, we will test it like it is. It is a 15 dollar heatsink, take it as how the manufacturer wishes it to be used.
One recommendation I do have for this unit. If you are planning to replace that crappy OEM heatsink that came with your Mom and Pop machine, then go for this one. It is quiet and does definitely does better than any no name OEM brand available.
Thanks to Ralph over at E-Compuvision for sending us this unit from Dynatron. Always a treat to see Micro Fin technology in action.
