Testing was done by running Prime95 for
an hour and taking the stabilized temperature at the end of the one hour.
Ambient temperature was 26 Degrees Celcius.

We see that the performance of the Microcool is only 1C
better than the stock cooler at stock speed of 1.6GHz. As we ramped up the
voltage and speed of the CPU, the margin between the 2 pulled apart, to
3C from each other. 3C is nothing to shout
about, but looking at the size of the MicroCool and the fact that it IS
essentially a chipset cooler, it is quite a good result. Granted, this can
never handle a non-mobile processor.
