Thermaltake Golden Orb II

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 temperature over time with the original AMD fansink:

The temperature starts at 41C and reaches 61C when running the stress test.

While the fan speed ranges from 3120 to 3180 RPM.

Note the RPM measurement and the reported temperature. Even at such a high fan speeds, the temperature won't drop below 40°C.

After installing the Golden Orb II, we ran again SpeedFan and after waiting for the processor to cool down to its idle temperature, we fired up the torture test once more..

Under the GOII the CPU temperature seems to have dropped dramatically

while the reported fan speed works at half of the RPM the stock one used.

Lets take a look at the results from Speedfan. In idle mode, the temperature with the stock cooler was 41°C, while with the GOII the temperature dropped to 37°C, a 4°C temperature drop. At full load, the stock cooler recorded 61°C while the GOII was only 53°C, a very nice 8°C temperature drop.

The temperature drops might not be the 10°-18°C we've been used too from other Tt Products, but we need only consider the RPMs of the GOII cooler to understand that not only have we had a significant drop in temperature, but also in noise levels. The reported RPM (1620RPM) makes this CPU cooler very silent.
