Guys it's pretty fast to just test it. If you won't, I will when I get home.
Some fan designs work better this way.
It works, i am seeing about 5 degree drop in temperature.
Those readings are working against physics and definitely not accurate.
Not necessarily. The difference between the efficacy of push or pull would be determined by the design and layout of chips/hot spots as well, not simply direction.
I have a Z9 mini myself and seen the inside, there is no way for an exhaust fan to be more efficient than an intake fan, placed either side of the Z9 mini.
Pulling air out of Z9 mini is like placing a dense fabric air filter in front of the intake, restricting the airflow and reducing the efficiency.
