The initial results peg the Arkua Q85x-7J a little higher than we would have anticipated - perhaps this little heatpipe cooler has more cooling ability than we gave it credit for. Let's find out!

Alright, with the final test numbers spread out like this we can see a few things more clearly. First off, the Arkua Q85X-7J is more efficient than the stock intel m478 heatsink (sub 3GHz model).

The twin heatpipes kick in to provide very good cooling ability, at a remarkably low volume of just under 50 dBA.

Sure steps were cut when it came to finishing the base nicely; its obvious that little care was taken to ensure perfect flatness, or thought given to machine the base of this heatsink. Even with those shortcomings the heatsink performs, so we're left with the question "does a perfectly flat base really matter if the thermal compound is good enough?"

It's a difficult answer in this case because the thermal numbers remain pretty good despite a sanded base finish and relatively flat base surface. In our tests we use CoolingFlow ceramic-based compound which is hardly exotic, but does the trick.

Perhaps the real effectiveness of the Arkua Q85X-7J comes down to the fact that all joints; from the base to the heatpipes, and the heatpipes to the fins are properly soldered. With a lower thermal resistance at each interface the heat that the Q85X-7J absorbs is quickly and efficiently dispersed.
