With the system running at stock setting the Phanteks PH-TC14PE come in at a nice 52.25*C on high,25 degrees cooler than the stock Intel HSF and only 2.25 degrees behind the Corsair H100 on high. The Phanteks PH-TC14PE on low came in at 54*C. On high the fans are very quiet and were not noticeable over my case fans. Compared to the H100 on low the PH-TC14PE is quieter.
Pushing the system with a mild overclock to 3.5Ghz the Phanteks PH-TC14PE came in at a very nice 56*C on high, nipping at the heels of the H100 on high. On low the PH-TC14PE came in at 58.5*C just behind the Corsair H100 on low.
Really cranking up the heat with the system overclocked to 4.0Ghz the Phanteks PH-TC14PE is still performing very well. Coming in at 70*C on high and 72*C on low. On high the PH-TC14PE is only a hair behind the Corsair H100 on low, but almost 5 degrees behind the H100 on high. Still at 70*C that is 7 degrees behind the stock cooling at stock settings.
