Applying a substantial overclock to the CPU, things are intensified. Whilst D15 appears to fall a few places down the chart in this particular test, we need to appreciate that the fan speeds of other cooling solutions which are above D15 are using increased RPM and therefore have to push harder to bring down the temperatures and this in turn results in higher noise levels. So with this in mind, D15 actually does a great job at just 1500RPM.

Fan Speed: Remained at 1500RPM throughout overclocked testing – noticeable but not disruptive.
