Dynatron Model-L Microfin Heatsink Review
Dynatron Model-L Microfin Heatsink Review
Abstract: Needless to say, when we opened up the generic white box the DC1206BM-L comes in, we weren't expecting to be surprised in the way we were.

Dynatron DC1206BM-L Heatsink Perspectives

The Fan:
A blue fan is a first for us, though I'm sure they have made it onto other heatsinks in the world. The 11-bladed fan pushes air into the microfins at a respectable 5300RPM. The fan connects to the motherboard via a three-pin connector, and has a lead for RPM monitoring.

Heatsink Top:
Were it not for clips, I'm sure heatsinks could perform a lot better. A ~6mm clip trough digs down leave a healthy 6mm of base directly over where the heatsink will mount on the processor. The four corner tabs hold the fan firmly in place about 4mm above the tops of the microfins. Each microfin has a profile not unlike that of a knife blade, except ever so slightly curved upward.

Side A:
Note the protective shell on the base. Each of the 23mm tall fins is 0.3mm thick and spaced exactly 1mm apart from one another. There are a total of 46 fins on this cooler - all of which have been 'shaved' from the main base plate. 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 does not distort the fins in any way. Interestingly, the edges of the fins are rather rough.

Side B:
The cut marks where the base was severed from the main component are still quite visible and underlie the precision of the whole affair. The Jaguar stamp and "Jagwire" brand on the aluminum shroud are for the shroud only (still I really like that name... Jagwire...). The clip used on the Model L is only operable with a flat headed screwdriver, but is not difficult to engage or remove from the socket.

Heatsink Base:
Heatsink makers take note of this base. Unlike many of the current heatsinks out there the Model L's base is both smooth and perfectly flat - a rare occurrence it seems. A small square of thermal compound is pre-applied to the base of the heatsink to further improve the interface. Curiously, a hard plastic shell protected the base on the unit we had for review - through we're not sure if this will find its' way onto the retail models.
