Testing and Results
So we all know what we are dealing with, here is a GPU-Z screen shot of my BIOS modded 9800GTX+. Plenty of clock to give these coolers a workout.
The test I chose to torture the coolers was Ozone3D's Furmark. Testing was run in stability mode for twenty minutes with all of the coolers tested. At this point I just click go and wait for the results.
After doing a few "burn in" runs, I allowed the cooler to rest a bit, then turned up the torture level and attained my results. These results show a 42 degree idle and 60 degree maximum temperatures, and this is with the stock GTS 250 BIOS controlling the fans speed. Pretty impressive for BIOS level fan control!
This image shows a 45 degree idle and a 61 degree maximum temperature, and this test was run by attaching the 3-pin connection of the fans to the 7 volt side of the 4-pin Molex adapter. Pretty impressive again!
The best results by far, and even to date on my 9800GTX+, is with the 3-pin connection moved over to the 12 Volt header of the adapter. 42 degrees at idle and a maximum of 55 degrees at load is very impressive indeed!
Now, with the chart right in front of you, let's do some basic math. The Accelero Twin Turbo Pro cooler makes for a huge 23 degree drop in load temperatures over the stock cooler, and even shows a 3 degree drop over the Zerotherm with only 7 Volts going to the fans of the TTP. Let me just say, I am a fair bit more than impressed at this point. With all this drop in temperatures there is the added benefit of the fact that during testing I wasn't able to hear this cooler over the PSU or CPU fan when everything was running, even at 12 Volts settings.
