Here are graphs with rpm range expanded so we can see both SF fan lines.
Your PWM % to RPM is near identical to the my graph you posted before.
Like MicroCat said, it is also within the 10% margin of error in specifications.
Thank you for that work!
Your results and mines are almost identical.
But i think the review one is a little "better".
Even considering that 10-15% margin is still 800 - 1000 at some point. 800+15% is still 920 rpm! Far from 1xxx.
But i think you are the master here, so ill trust you!
Ill try to get a "better" or quieter fan then, maybe a thermalright one.
While i try to find it ( i dont know why, but at least in my country, thermaltake distribution is really bad, and the prices and a little high) i discover a "silent" option among the fan expert features :S.
That gives me a "better" curve.
I dont know how, but this could be a temporary solution? :S
And its "secure", i mean, i know thats the range of quieter fans, but dont know if the xf140 could keep the cpu cool with that low rpm :S.
