I believe that is the case! The SilverArrow has been replaced with the SilverArrow SB-E. There is also the 'overkill' one, and designed that way! The Silver Arrow SB-E Extreme. The review only covers a handful of coolers. I would have been interested to see how the Xigmatek Dark Knight Night Hawk edition would have gone, since that has got good reviews on some sites (and it's the one I have). There's no denying the Noctua is one of the best coolers available, but the results are a little surprising. The limiting factor in the ability for a cooler to cool is the weakest link. The weakest link in this case is the thermal interface between the actual chip and the integrated heat sink (IHS). Now, is the temperature the core temperature or the temperature of the CPU? At the moment I'm doing encoding in a room that is mid to high 20's (celsius), the CPU temperature is 40C (remembering I am running at 4.4Ghz, 43x102.33). but the individual core temperatures are range between 55C and 64C depending on the core. Actually one core is going down to 50C or less at times, I guess that depends on the thread load on that core. At the 4600Mhz, 1.3V load test, the CPU temps range between 72C and 96C. I would think if it were the CPU temps, the core temps would actually be significantly higher than that? What if, during the test, the cores hit their thermal maximum and throttling was invoked, does the test take that into account? I suspect that for the NH-D14 that either throttling may have played a part, or the different CPU mounting pressure meant that the limitations of the interface between the actual core and IHS were slightly overcome. Otherwise, it would be a 'sucked in' to all the idiots who have gone for the inferior Corsair H100 water cooling. Higher temps, more noise, crapper! (just stirring here, I believe the H100 should have done better).
