ARCTIC F12 PRO PWM PST - Ultra quiet PWM controlled 120mm case fan with unique anti-vibration system & PST terminal (PWM Sharing Technology) (Personal Computers)
The fan sucks the air out of the PC case, if you installed it as intended - that was not clear to me at least, as I ordered the part. I wanted my graphics card blow a little to lower the temperature. So I have the fan turned and fixed with adhesive pads on the ground - is working properly. As a result, the temperature is about ten degrees lower than previously. (Although I now also know that graphics cards can be considerably hotter and allowed as the CPU. I've left so precisely because no noise emanating from the part.)
It remains to confirm what others have written: - Very quiet, smooth running - Connection of this fan and CPU fan easy, both rotate at a low level.
I'm curious to see how the system proposes when it should really be hot outside in the summer.
