Dynatron Model-R 1U Cu Microfin Heatsink Review
Dynatron Model-R 1U Cu Microfin Heatsink Review
Abstract: The market for 1U servers is increasing rapidly these days as data centers increasingly move away from the bulky 3U and 5U servers that were once the staple of websites.

Dynatron DC1206BM-R Heatsink Perspectives

The Fan:
A blue fan is indicative of a 'cool heatsink' I guess. Personally it's kind of refreshing to see something other than a black fan, but then fan styling have yet to break out as a 'feature'. The 11-bladed Top Motor fan pushes air into the Microfins with an RPM of 5300RPM. The fan connects to the motherboard via a three-pin connector, and supports RPM monitoring.

Heatsink Top:
Like the other heatsinks with Microfin technology the Model-O just looks like it means business. I would have really liked to have seen the fins oriented differently and a wire clip used to go between the fins, rather than having to cut a 6mm path however. The four corner tabs hold the fan in place about 4mm above tops of the Microfins. The aluminum shroud seems a bit flimsy, the heatsink itself is very well made.

Side A:
This heatsink is exactly 24mm tall. The Microfins (all 60 of them) make up no more than 7.0mm of that total height. The base measures ~8mm thick and is undercut to make room for the socket cam arm. The fan is screwed into the fan shroud and barely clears the tops of the fins. Interestingly, the edges of the fins are rather rough.

Side B:
This is where I have a few issues with the Model-R. While the heatsink itself is very well made, the fan shroud is too flimsy and the quality of the clip quite poor. Now that is not to say the clip won't hold the heatsink firmly in place, it's just that engaging the clip is difficult. The tab where the screwdriver is inserted is not very well thought out and it makes the whole process more complicated than it really ought to be.

Heatsink Base:
I really love this base :) Shinny, perfectly flat (tested with a straight edge having a tolerance of less than 0.0001" deviation over 12") and smooth. Like all Dynatron heatsinks we've seen, this one came with the base protected by a hard plastic shell. A small square of thermal compound is pre-applied to the base of the heatsink to further improve the interface.
