Dynatron 2-Way Socket-A Shootout (Model # DC1206BM-O and DC1206BM-L/610-P-CU)
Supplied By: Dynatron:Kenny Kwong


First off, welcome to another first. Today we will have our first 2-way shootout.

Dynatron is a company that is in the business for a very long time. Since 1991, they have produced many great products. They are specialist in thermal management. Today’s computers run hot, therefore Dynatron has been producing products that can cool them down.

Today we will put the Dynatron DC1206BM-L/610-P-CU and the Dynatron DC1206BM-O through extensive testing.

First off, we take a look at the Dynatron DC1206BM-L/610-P-CU HSF for AMD CPU’s.

Dynatron sent both coolers in a white box. However, along the way I assume that the UPS driver drove too quickly. Thus, the box was in some dented looking damage. Thankfully, there were bits of Styrofoam for protection. Nonetheless, the Dynatron DC1206BM-L/610-P-CU was not damaged in anyway.

Both coolers we are reviewing today utilize Dynatron’s advance MicroFin technology (aka Skived Fin Technology) that helps to dissipate heat quickly. The fins are spread apart evenly and have no edges where they will cut you. The base of the Dynatron DC1206BM-L/610-P-CU is made of Aluminum A1070 and has a copper inlay for better heat dissipation. The finish was very good also. It weighs in at a moderate 236.32 g.

Dynatron opted to use pre-applied thermal tape, but an evenly spread out Arctic Silver 3 was used for testing.

Dynatron utilizes a 1-lug clip mechanism. Usually I do not recommend 1-lug clips; however in this case, installation was very easy.
Fan speed is rated at 5300 RPM and pushes 24.4 CFM’s of air. Listening to this cooler, it was quite loud, but was bearable. The fan produced a whine that you will sure hear. This may not be good for people who want quiet for their existing setup.

This all sounds good, but does it work? Well, we will see when we get there. My initial prediction is that it will cool my AMD ATHLON XP 1900+ not very well. I say this because it's so small! I could not see this heatsink fan doing any better. I wonder if I will be right.

The Dynatron DC1206BM-O is a bigger brother as opposed to the DC1206BM-L/610-P-CU. It is constructed out of Copper C1020 and weighs in at 435 g.

The DC1206BM-O utilizes the same MicroFin technology as it’s younger brother. The only difference is the use of cooper to dissipate heat quicker.

The clip mechanism that was installed, was a 1-Clip design. Fortunately, Dynatron has an option for a 3-three clip mechanism. I chose to utilize it. It makes me feel more comfortable.

Now there is one thing that I am dying to say. The fan pulls 37.61 CFM’s of air at a sound bottling 46.5 dBA’s. OMG! this Delta fan was LOUD. It sounded like a blow dryer. I could not stand it at all…Period. It actually scared me the first time I booted it up. I believe hearing this for 24 hours straight can give you permanent ear loss, so I advise you…


Testing consisted of both cooler cooling an AMD ATHLON XP 1900+. Both idle and load temperatures were monitored by Winbond Hardware Doctor on an Abit NV7-133R motherboard.
Load temps will consist of 1 hour worth of loops of UT 2003 and secondary load temperatures came from running Toast for 5 minutes.
The ambient room temp hovered around 21-22c.


Dynatron DC1206BM-0 Results

Idle: 39c
Load (UT 2003): 45c
Load (Toast): 48c

Dynatron DC1206BM-L/610-P-CU Results

Idle: 44c
Load (UT 2003): 49c
Load (Toast): 53c


There you have it. The results speak for themselves. The Dynatron DC1206BM-0 came out with the best result with the coolers I have tested so far. However, there is one major gripe I have. I would classify this cooler as an Xtreme cooler category simply because of the annoying LOUD! fan that it uses. Although it produced great temperatures, the fan brings down the mark. Also another thing I did not like was the base. As you can see from the photos, the base had some nasty machine marks and spots which apparently look like corrosion marks. Overall, a really great product for people who are looking for Xtreme cooling with Xtreme noise to kill you.:)

The Dynatron DC1206BM-L/610-P-CU (green one) on the other hand faired extremely well than I thought. I was simply impressed and at the same time awe struck with the result that it put up. Sound levels were another factor that I did not like. It was quite than the Delta fan but was annoying after long periods of time. Overall, a great product.

I'm going to have to rate the Dynatron DC1206BM-0 a...

8/10! (Recommended to those who want Xtreme cooling with the addition of LOUD sound)

+ Great clip design

+ Copper

+ Excellent results

+ Build Quality


- Questionable base


- Did I mention it was OH-SO LOUD?

- I sense ear loss...DELTA....WHAT DID YOU SAY? I COULDN'T HEAR YOU..........


I'm going to give the Dynatron DC1206BM-L/610-P-CU heatsink fan a...


+ Great numbers (proved me wrong)

+ Great clip design

+ Build Quality

+ MicroFin Technology works wonders

+ Base finish was excellent

- Still quite loud for amount of air the fan pushes


If you want Xtreme cooling and very good cooling, pick up both heatsinks from Dynatron by emailing Kenny Kwong.

Let me thank Kenny Kwong from Dynatron for making this shootout possible.
