Great review, but, should the passive cooling test last for a bit longer, because even with the best heatsink in the world, over time the fins would heat up and the temperature of the processor would increase. Maybe if you had a time vs. temperature for the cooler it would be helpful.
On another point, would this handle the QX9770 (at 4.0 ghz), I move my computer far too much to want to water cool it, so I need decent air cooling. I'm getting idles of 51, 52, 36, 41 and loads (after 20 mins of cpu burn at 100% cpu usage) of 59, 57, 58, 61
