ARKUA - MODEL 6228 AND 7228 HEATSINKS 

Arkua 7228

The 7228’s packaging didn’t have the same bold proclamation as did the 6228.  Just a Plain Jane box that was a bit more sizeable than the 6228’s.  The Arkua 7228 is almost a twin to the design of the 6228 with the exception that it has a larger footprint.  A six millimeters larger footprint to be exact. 

Upon inspection of the 7228, pretty much all facets of the product are the same as the 6228 as we have said before, just bigger.  The same copper recessed core, clip, and fin design are all there.  Again, with the recessed core not being the same height as the fins, who knows?  Seems like such a waste of an opportunity to expand the sink’s cooling capacity.

Installation

We discussed the clips and their solid design above.  Installation of the 6228 and the 7228 went smooth as glass on the ABIT KT7A in our test box.  As with any oversized cooling product, be as sure as possible that it will fit your mobo before you lay down your hard earned jack.  Jens over at OC Inside, has an excellent database that allows you to picture different sinks on to different mainboards to make sure your potential future sink will fit your mainboard.

Performance

For comparison we are going to use our Vantec CCK-6035.  With the popularity of the Vantec CCK it makes an excellent comparison heatsink to give you some perspective on our test results.

Now our cursory statement…

No two systems will perform identically, or for that matter, there will be variations within a single system to some degree depending on several factors.   Hence our results may end up being a little better or a little worse than the results you may get in your own box.

All measurements were obtained by a thermal probe mounted on the top of the silicon of the chip so that the probe tip touches the CPU core.  Our load temperatures were attained by running the CPU stability tester program for thirty minutes.  The reported results are the average of three runs per product.  Arctic Silver thermal goop was used as our interface material in all tests.  Ambient room temperature was 76.2 degrees Fahrenheit and at no time did this base temperature deviate more than 0.5 degrees F.
