Allan Campbell, Founder and
Editor-in-Chief of KitGuru.com picked Noctua's award-winning NH-D14
cooler for his overclocking tests on Intel's latest Core i7 875K and
Core i5 655K processors achieving a stunning speed of 4.8GHz ... setting
a new world record for the K-series CPUs on air cooling.
"This cooler is without a doubt my favourite on the market right now and
I have achieved results very similar to good water cooling.", says Allan
Campbell. "It is a brute for sure but the results are unmatched on air
and it has a place in my heart now for every serious build I create."
Noctua's NH-D14 cooler has won more than 150 awards and recommendations
from the international press since its introduction last November and
has been chosen by first-tier websites such as Tom's Hardware for their
overclocking tests on Intel's new K-series CPUs. As KitGuru's tests have
shown, the NH-D14 can help to overclock Core i5 and Core i7 CPUs to
speeds previously thought impossible on air cooling.
In order to achieve these outstanding results, KitGuru increased the CPU
core voltage to 1.42V on the 875K and 1.46V on the 655K. Despite the
enormous thermal overhead at such high voltages and 4.8GHz, the NH-D14
managed to keep the processors rock stable at load temperatures of 87
and 79 degrees Celsius respectively. KitGuru even reached the 5GHz
barrier on the 655K but the system didn't prove entirely stable at this
speed. As Allan notes, this is "a staggering result and it shows just
how capable the Noctua cooler really is."
