Question 1

Is the airflow for the 120mm and 140mm fans the same?  If so, why?  Is it a mislabel?

Accepted Answer

I have both in my system and I feel like the 140 pushes a noticeable amount more air, but perhaps since it's over a greater surface area the math works out to the same CFM rating, and Cougar doesn't want to advertise falsely. But I could be wrong, it could be a mis-label too. Either way, both the 120 and 140 are amazing fans.

Question 2

The product description mentions an adapter that makes the airflow better at lower RPMs, what is this and does it come with the fan?

Accepted Answer

In the 4th picture, there is what looks like a cable with a male and female end and it almost looks like heat shrink tubing, there is a resistor in there to slow the fan. So yes, it's included.
