Sibak AC06725TH Copper Core Heatsink Review
It's amazing sometimes how heatsinks almost don't get reviewed. Take for example the
Sibak AC06725TH. Sibak parted from the trusty and reliable DHL, or EMS, and
sent the heatsink you see below by parcel. This is a risky proposition between Canada and
the US, but even more so when the package is coming from Tiawan!
Several custom's forms, a hefty duty fee, and one
beat up box later the Sibak was ready and raring to get reviewed.
At first glance the
-725th is a simple adaption of a rather popular heatsink design. On
closer inspection we found a nice solid copper plug in the base, and a
very loud, and very powerfull fan bolted to the top of the heatsink.
The fan, with its grill really isn't one piece, and so it takes some of its
cues from Thermaltake and what they have been using for some time now.
The fan and the aluminum frame which protect it
are each screwed to the heatsink with separate mounting points. In the photo below
you can see the bare fan motor and blades. Below this
lies the heatsink clip which sits in a small recess. The copper insert does not
come all the way up to the surface of the heatsink however so it is
hard to say just how large it really is.
The way
Sibak have assembled this fan is rather unique, but I have to wonder if placing the
fan and the protective shroud like this isn't the main reason
that this heatsink creates so much noise? After all, the fan is fairly high RPM, so
it only seems to make sense that if it is not properly centered in the shroud that
even airflow might be the source of noise issues.
The base
at least is completely free from questionable problems.
The copper insert - whatever its real size may be - is set flush to
the surface and perfectly flat and smooth. That is exactly the way we like to
see things!
