With the system at stock settings, the Jing running on high cooled our Intel Core i7-930 to 59*C, 4.75 degrees behind the Prolimatech Super Mega and 20.5 degrees better than the stock Intel HSF. On low temps climbed to 64.75*C.
With the system bumped with a mild overclock to 3.5GHz the Jing cooled the CPU to 67.75*C, 7.5 degrees behind the Prolimatech Super Mega, and 5 degrees behind the Corsair A50. On low the Jing comes in the back of the pack at 72.5*C; that is still better than stock cooling at stock settings, and a whole lot quieter.
Then I pushed the system to 4GHz.The Jing comes in at 78.5*C, 8.25 degrees behind the Super Mega, and 3.25 degrees behind the Corsair A50. Even at 4GHz the Jing is still keeping the CPU cooler than stock cooling at stock settings.
