Introduction 

Would a ThermoEngine by any other name still smell as sweet?  You bet your ass it would, perhaps even sweeter.  Arkua Technology came out of a split of sorts ThermoSonic had some time back.  They are now producing cooling solutions utilizing the famous and very effective ThermoEngine design. What they produced was a blending of current technology with design of the original ThermoEngine.  Since the original ThermoEngine there have been numerous developments in cooling technology.  Mainly the more expanded use of copper.  Several manufacturers have started dropping copper inserts into their heatsink cores; so why not do it to here?  Will this breathe new life into the heatsink that was the litmus that many others measured themselves up to, not too long ago?  We want to thank the folks from Arkua Technology who were kind enough to send the Arkua model 6228 and model 7228 heatsinks over for us to review. 

Arkua has sought to meet the demand for better cooling solutions with two separate products.  These two being the Arkua 6228 and Arkua 7228.  The main difference between the two is in their size.  The 7228 is an oversized model of the 6228.  Let’s take a closer look at these two beauties.

Arkua 6228

The first thing we noticed when we looked at the package was the bold yellow sticker proclaiming something in Taiwanese and “over 2.4GHz” in English.  It seems apparent what is being said here even though I do not read Taiwanese.  Removing the 6228 from the box gives us a view of a very familiar looking sink on the surface.

The overall construction quality of the unit is quite high.  The fit and finish of the 6228 is definitely noteworthy.  The 6228’s base shows four spines radiating out from its center.  The center of the sink has a copper cylinder insert that extends from the base all the way through the heatsink.  Unfortunately, Arkua sees fit to ship their units with a TIM pad, which we promptly removed on ours.  This is a wild stab in the dark but anyone purchasing a high performance aftermarket heatsink probably will have the same TIM aversion that we do.  Hint hint all you heatsink makers, quit making us go through the trouble of scraping the funky TIM off.

In removing the fan…

With the top of the 6228 exposed we see that the central area of the sink does not extend up to the same height as the fins.  For the life of me, I cannot see the benefit of doing this other than to save weight or money in the manufacturing costs.  By decreasing the mass of the sink’s center, specifically the copper center, the heatsinks thermal capacity is reduced.  

The clipping mechanism is the same one we have known and loved from the original ThermoEngine.  With the clip’s center being elevated to go over the top it adds a measure of stability once mounted.  As shown below the clip’s hooks are fairly standard jobbers with a slot cut into the top so the hook can be pried on and off the mainboard catch.  Elementarily simple but extremely effective.
