For our temperature tests we loaded the system for 10 minutes using Prime 95 and recorded the CPU temperature using CPUID HWMonitor. We then restarted the system and left it idling at the desktop for 10 minutes before recording idle temperatures. The temperatures recorded are based on an ambient temperature of 20 degrees C.
We can see from the above results that the NH-D15 offers excellent performance when overclocked, cooling our i7-3930K to more than 5 degrees C cooler than the Phanteks PH-TC14PE.
I’ve never liked Noctua heatsinks because they’re way too bulky. It’s a nice product don’t get me wrong.
Why is it being compared against the U14 which only has a single tower? Why isn’t it compared to the D14? I’m curious as to improvements in regards to cooling, not just form factor.
