I measured all temperatures (GPU, CPU, Case) with RivaTuner 2.1 in a room of temperature 25oC. I also double-checked the GPU temperatures with ATi Tool and ATi's Catalyst Control Center. Load scenarios were created with both the processor and the card at full load in order to simulate the most heat possible in the case. The processor was loaded with two instances of Folding@Home, one on each core, the GPU with ATi Tool's 3D view.

Because there is not enough room in my case for both the Accelero S1 and my side exhaust fan, I did my best to tape paper to the inside of the hole in the window, so as to simulate a closed case and maintain correct pressure scenarios.

First I measured the stock cooler, then at 100% fan speed (Boeing 777 style). Next, I measured the S1 with both the front intake fan unplugged and running at full speed, to see if this pressure difference really mattered to the Accelero S1's performance. Other fans include a rear exhaust fan, a PSU exhaust fan and a fan on the CPU heatsink.



As you can see, in almost all cases the Accelero S1 outperformed the stock cooler, except with no sound. It appears that the most attractive option is to run the S1 with air running through the case and out the back, meaning that air passes over the fins and eventually exits the case. This is good news for the rest of your components, because with all fans blowing outwards, the only place you're getting good enough air throughput is over the Accelero S1, and the others are getting minimal air, which means that the case temperature gets pretty high and your processor and hard drives, etc., become much hotter. Now that you've seen what it can do, let's wrap this up.
