Introduction

A definite trend has emerged to satisfy the enthusiast want for quiet performance.  We have seen Akasa AK268 with its low speed fan, the Evercool CUD-725 Heatsink & Kingwin KCU-725 with their higher volume but less noisy 70mm fan, the Global Win TAK68 with twin 60 x 60 x 10mm fans, as well as the variable rate fans seen on the Tt Volcano 7, and Global Win CAK II 16.  Tt has even produced fan speed adjustment switches to be included with some of their heatsinks.  Each of these sinks performed at least at the level of the venerable Vantec CCK-6035 which we use as our comparison cooler in testing.  The Vantec of course is anything but quiet with its Delta screamer up top.  The point I wish to illustrate is that high end performance no longer requires you to lose your hearing in the process of cooling your processor.

It was only a few months ago we reviewed the Arkua 6228 heatsink.  It showed to be a solid performer with its ThermoEngine design coupled with a copper core.  Fast forward to March 2002.  The good folks from Arkua sent over their quiet performer called the Arkua 628.  The 628 is the same as the 6228 but with a lower speed fan up top so to eliminate a bit of racket.  Being that the 628 and 6228 are the same product, I'm not going to do a review of the sink itself since that information can be found here.  (The sinks are the same but not the fans.)  We intend on getting right down to brass tacks and put this puppy through the ringer.  Below are some pics of the Arkua 628.

Performance

To test the sink we ran our usual CPU Stability Tester program to put the CPU at a 100% load for half an hour.  As usual, we are throwing in our Vantec CCK-6035 to provide some perspective on the performance numbers we get. 

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.  The reported results are the average of three runs per product.  OCZ Quicksilver thermal goop was used as our interface material in all tests.  Ambient room temperature was 72 degrees Fahrenheit and at no time did this base temperature deviate more than 0.5 degrees F.
