Testing and Results
Testing was done in a spare computer I have in the room. Things were housed in a BitFenix Colossus and the door was on during any testing and reading of the temperatures. The room itself was kept at 25°C for the duration. To test the cards I used EVGA OC tool with a Furmark-like OpenGL 4.0 to test things. The card is controlled with MSI Afterburner for the overclocking and overvolting parts of the testing.
When the testing says stock fan profile, it is the one programmed into the BIOS. When the results show an adjusted fan profile, they will use the slope I set in Afterburner.
The testing is run for thirty minutes and temperature information is gathered from Afterburner for all the test results. In order to attain the idle temperatures, things were allowed to cool down and a reset was done and an additional ten minutes was waited to allow for the best possible results.
Idle: Cards were left at stock with clocks of 608/837/1215 with a voltage of 1.000V.
Load: Cards are overclocked and overvolted to clocks of 775/950/1550 with a voltage of 1.050V.
While not quite as good as water on the idle testing, I was able to reduce the idle temperature by over half of what the stock cooler offered out of the box. Even after I adjusted the fan profile of the stock cooler, the AC comes back and does almost 20°C better than stock. If you have the room for this monster, so far the temperatures are showing it is doing a great job on this Fermi.
Loading the GTX 470 with the Accelero XTREME Plus showed great results on the core, and also a 20+ degree drop in PCB temperature. With temperatures as low as 51°C achieved with overclocking and adding volts, you think I would happy, right? Well not exactly. With the aid of my handy IR temperature gun I scanned the PCB while the testing was running. I found that with the scanner running, the plate on the voltage regulators was allowing a temperature of 98°C. Now that isn't a critical temperature, but with the rest of the cooler working so well, it's a shame the aluminum cooler here isn't sufficient to really push these GPUs to their maximum levels.
Noise level testing was impossible to get with the Accelero XTREME Plus. Reason being is that the power supply and the H70 that cools the CPU were much louder than the cooler even at maximum fan speeds. I hooked power through the adapter up to the fan outside the case. When I went to test with the meter, the noise was too low to register. When I put my ear up to the cooler out of the case, I could barely hear a hum coming from it, and to be quite honest I would do it a great injustice to guess at the level.
