Vantec Mach1

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 starts off at 46°C...
and here is the reported fan rotation speed...

The reported temperature for the Intel Prescott 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 Vantec mach1 and let the processor idle for a few minutes so that the temperature could settle. We then went on with the Prime FFT torture test once again, pushing the CPU to full load. Here we will be testing the Vantec cooler at High and Low Fan speeds. Let us start of with the Low mode first...

It is very likely that the first time you may not notice any great difference in temperatures. You need to give the thermal compound a little time, approximately a day, to reach optimal performance.

Low Fan Speed

starting from 44°C in idle mode...
the RPM graph settling to just under 2900 RPM

At the low fan speed, the mach1 started at 44°C and after torturing the CPU with the in place FFT prime test, the temperature climbed up to 60°C. What we got was an amazing 7°C drop while the rotation speed ranging between 2850 to 2950 RPM. We then proceeded and set the fan speed switch to "high" to see what more the Vantec cooler could give.

High Fan Speed

starting form 42C idle mode climbing up to 56C
a little higher than the manufacturer states...

At high speed, the mach1 managed to drop the temperature by a further 2°C in idle mode and 4°C at full load. This is great performance from the Vantec cooler as it managed to reduce the CPU temperature by 11°C at full load compared to the original Intel cooler.

The temperatures reported were reduced dramatically by the Vantec mach1 CPU cooler, but at the cost of noise, which is a slight drawback. Nevertheless, great performance by the mach1 fansink.
