Testing and Overclocking
CPU: AMD Phenom II 1090T
GPU: ASUS Reference 5870
Memory: 16GB Corsair Vengeance 1600MHz 9-9-9-24 DDR3
Storage: Crucial C300 128GB
PSU: Cooler Master Silent Pro 850W
OS: Windows 7 Ultimate x64
Case: Corsair 700D equipped with many fans
To ensure the results were consistent, the heatsink was mounted three times and idle and load tests run each time. An average of the results is shown below.
For idle testing, Windows 7 was allowed to run with no programs for 10 minutes.
For load testing I used Prime 95 Small FFTs and temperatures were taken after 20 minutes.
The standard thermal paste, provided with the cooler, was used.
The settings we used for our stock and overclocked tests are:
Stock – CPU 3200MHz Auto voltage at 1.325v
Overclocked – CPU 4000MHz at 1.456v
NB: Due to thermal probe built into the Phenom II CPU’s being incorrectly calibrated, the temperatures displayed are 5C cooler than the actual temperature of the CPU. The temperatures are all taken from the same CPU so are all on the same scale.
With the fan running at the fan 1300RPM, we saw very impressive results. With the CPU only reaching 31C when load was applied to the stock clocked CPU, that’s one of the best results I’ve seen yet, beating even the Prolimatech Panther. The Silent mode adaptor only added 4C on to the load temperature, excellent.
Due to an issue with our graphing script, the following results needed to be collected seperately, though they were taken in the exact same environment as the above table.
With the fan running at 1300RPM again we reach 49C under load with an overclocked CPU. Another excellent result for the Hyper 412S. With the Silent mode adaptor the temperature rises to 58C. Still well within specifications of the CPU.
With some different fans mounted on the cooler we see only 45C with two Gentle Typhoons mounted, just keeping up to the Prolimatech Panther this time.
