These are my short thoughts and experiences with the Accelero X2 installed on my ASUS EAX1900XT.
Both Coolers temperatures were measured using ATI Tool and fan speeds were set at 100% for both of the cards. Temperatures are taken from ATI Tool, from 3 indicated temperature readings; GPU Temp/Temperature of voltage regulators/temperaturse of temp.chip. Idle was measured from desktop, just ATI Tool running, and load was taken while running ATI Tool artifact scanning for several minutes (6-10), when the load temperatures were stabilized.
At 690/800 Stock Cooler Idled at 49/59/47 (GPU/volt.reg/temp.chp), and load temperatures were: 75/79/60.
With same 690/800 Accelero Idles at 47/59/43 and loads at 76/83/54.
temperatures didn't fall, and the card seems as stable as id did with stock cooling at high overclocks (690/800) but is silent at 100% fan speed. I don't now is that kind of what I expected or am I little dissapointed. For me it seems that it cools almost as well as Stock cooler at 100% fan speed, but does that without noise. Though I expected the GPU temp to be bit lower.
I currently have Antec P180 case and 4 (3 in the upper chamber and 1 in the lower) 120mm fans to handle the case cooling. GPU temperatures seem to be only 1 degrees higher, but chipset runs 4 degrees higher (41 vs 45, ASUS A8N-SLI Deluxe).
What would be the best way to verify that the videocard overclock is stable? Running ATI Tool Artifact scanning? at clocks set to 690/800 I runned it ok for over 5 minutes, and I stressed it with 2 hour 3DMark06 looping and by playing BF2 for 3 hours. no crashes yet, but does it sound enough?
