Test System and Thermal Results
I would first like to thank ASUS, InWin, Corsair and Fractal Design for supplying products for me to test with. To see our testing methodology and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article for that information.
With stock settings applied to the test system and after a few runs with the pipes in both directions as they were oriented to the fan, we got a result of 55.5C, which is pretty admirable considering it sits in fourth place overall right now.
Since the PWM controller is dealing with the fan here, we also recorded that the Silent Wings fan was spinning at 1137 RPM at the hottest point of the tests. As for the idle temperature, the Shadow Rock 2 sits at a solid 28C when left to idle, and the fan was spinning near 650RPM.
To be blunt, I really don't know what happened to the Shadow Rock 2 in this test. With the pipes of the cooler set both directions for the various rounds of testing we do, no matter what I tried, I could not get better results than the 80.25C average that is shown in the chart.
I did have a feeling that this new test rig would be weeding out some coolers on an efficiency level unlike the systems before this, it just surprises me that even with the fans spinning at 1700 RPM, that it is the Shadow Rock 2 that is the first cooler to show this.
I discussed this with BeQuiet, and they say that results are showing up with a variance in results, and they are aware of it. One can only hope they find out why and address this as soon as possible. Also, with the OC applied and the fan spinning full speed, the idle temperature was 28.5C.
