| Thermaltake DuOrb Heatpipe CPU Cooler
|
Testing:
To test the thermal performance of the DuOrb, the idle and load temperatures were monitored using HWMonitor 1.1.0 and RealTemp 2.70. Prior to the review, I had been using HWMonitor for all temperature monitoring, but I think there needs to be a patch to the program for the 790i chipset as the core and system temperatures recorded were very high, even at stock speeds. I found RealTemp to be a little more accurate compared to HWMonitor and the built-in OCCT readings.
The idle condition was established by powering the system without running any other applications for a period of at least 30 minutes. The load condition was established by running OCCT 2.0.0a along with 3DMark06 for a period of at least 60 minutes. The Intel Core 2 Duo E8400 CPU used in this review was also overclocked and overvolted to create more heat (from a frequency of 333x9 to 400x9, and from a voltage of 1.10V to 1.36V).
For comparison purposes, the cooling performance of a Kingwin KA-9225 Heatpipe CPU Cooler will also be shown. The thermal results for both coolers were achieved while maintaining an ambient temperature of 25° Celsius in an open chassis:
The results in the chart below are from HWMonitor. The CPU temperatures are from the reading of the physical CPU, while the core0 and core1 temps are from each core of the CPU. The Thermaltake DuOrb outcools the Kingwin KA-9225 with ease in each test result.
The thermal results from RealTemp are provided in the chart below. This test did not include the CPU temperature, but the more accurate core readings are included. Again, the Thermaltake DuOrb outperforms the Kingwin KA-9225 in both core temperature readings.
The two images below were from the 60 minute OCCT stress test. The below left image is of the first CPU core's temperature throughout the test, which topped out at around 67° Celsius. The below right image is of the second core's temperature, which topped out at around 63° Celsius. These temperatures were the same as in the HWMonitor thermal results.
