Arctic Cooling Freezer 7

3. Performance

The test PC that was used for this review of the Arctic Cooling Freezer 7 Heatsink...

the test PC specs, as reported by CPUZ
motherboard info by CPUZ...

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. First, we let the processor cool down in idle for a few minutes, and then we ran the Prime 95 - In-place large FFT test to heat it up to its maximum level. Lets take a look at the graphs with the Stock Box Intel Cooler first...

in idle mode, the CPU reported 40°C..
the stock box's cooler fan goes up to 2800 RPM

The Intel stock cooler starts from 40°C in idle mode and rises up to hit a max for 55°C under full load with the FFT Torture test...

Now lets have a look at the graphs for the same procedure repeated with the Freezer 7 installed...

5°C temperature drop, both in idle and full mode...
the average speed of 2500 confirms the specifications...

The temperature differences are noticeable and more than welcome in this case. It never ceases to amaze how such a small cooler can make a difference of 5°C from the outset while also running at a lower fan speed. It would be interesting to see the temperature drops after the 200 hours that the paste needs to "harden". We got a drop of 5°C in both full and idle mode. Notice that same temperature drops were achieved with the Freezer 64, the AMD based cooler of the same technology.
