Spire QuieTude VI

3. Performance

To measure the CPU's temperature, we used SpeedFan v4.24 which provided us with real time monitoring and created a graph of the temperature over time. After letting the processor cool down in idle mode, we fired up Prime95 and ran the in-place large FFT test to heat it up to its maximum level. This is the graph of the temperature with the stock Intel fansink:

The temperature started at 45C...
and here is the reported fan speed...

The reported temperature for the Intel Prescot CPU and stock CPU cooler, was 45°C at idle mode and rose up to 67°C as the Prime FFT torture test was put to work.

We installed the Spire cooler and let the processor idle for a few minutes so that the temperatures would drop. We then went on with the Prime FFT torture test once again, pushing the CPU to full load. This is what we got..

the temperature in idle mode is the same as with the stock cooler...
the RPM graph under the Spire cooler

As we can see from the above tests, we didn't get any drop in the final temeprature. Tthe Spire cooler, simply managed to delay the rise. The big difference however was the significant noise reduction that we achieved with the Spire cooler, even if the RPM average was 100 rpms faster that the stock cooler.

We saw how the Spire cooler works under certain circumstances, that of idle and full load. What we got was noise reduction, but unfortunately not any temperature reduction.
