The Intel Core 2 Duo 6800 Extreme Edition is our test bed processor, and boy did we test a lot of stuff with it. In demanding tests its temperature easily rises above 70°C, so a good cooler is necessary for good performance, especially with an overclocked processor. We didn’t try to break any records today, we clocked the processor to 3,333MHz at 1.4V, with the FSB at 1,333MHz. We didn’t meddle with the memory and it stayed at 1,066MHz. The room temperature was high, 25.6°C.
The pictures are here to show you both coolers. For testing we used a Gainward Geforce 8600GTS 512MB card. Although from the picture it appears that the Freezer 7 Pro reaches all the way to the memory modules, there is a 1cm gap. That’s not so bad considering that the fan is sucking hot air off the modules and using it to cool them. If you’re using additional memory cooling, you can rotate the Freezer 7 Pro by 180 degrees.
For starters, we measured the temperature using the Akasa EVO Blue cooler that we’re been using for a long time and we can definitely recommend it to anyone. It’s Socket 754/939/775/AM2 compatible and therefore available to everyone. It’s got a manual fan speed controller, and is completely silent at low speeds. We can say the same for the Arctic Cooling Freezer 7 Pro.
We tested it in two separate scenarios. The first one uses the default speeds of the Core 2 Duo 6800 Extreme at 2.93GHz, and the other one was done after we overclocked the CPU to 3.33GHz. We measured the temperatures at both idle and under a load.
The Freezer 7 Pro confirms its good reputation. When we increased the fan speed to its max, the Freezer 7 Pro cooled the processor to 59°C which is 3°C cooler than the Evo Blue. In idle mode, when the fan is almost silent the temperature reached 50°C, and at full speed it reached 44°C. The fan isn’t that loud even at full speed. Our EVGA 680i chipset fan was louder.
When the fan is running at 60 per cent speed, we see that the processor running at 3.33GHz under full load is operating at 72°C; exactly the same as for the Evo Blue cooler. At full speed we see an 8°C difference. This time the Freezer 7 Pro simply blows away the competition.
The Arctic Cooling Freezer 7 Pro has been available for quite a while and it’s got a massive reputation, especially for Intel Socket 775 processors. We tried to find any reason to dispute its title, but we couldn’t find one. Low price coupled with excellent performance speak for themselves. In Germany we found it priced at €13.34 + shipping.
We recommend this to anyone who wants a good cooler; it can be used by both beginners and the overclockers.
