2 fans stacked on top of each other blowing same direction?

Has anyone tried putting 2 fans back to back. Both pushing air the same direction?



My case has an intake fan, but you cant see it from inside the case. The interior is red and black theme. Just wondering what would happen if I stacked another fan ( corsair AF 140mm red/black ) directly behind the non visable intake fan.

There's no point. It's not going to help. You'd probably get poorer airflow.

Wont do much good. Since they are spinning at the same RPM, if they are the same fan. Both might jump up the RPM slightly but not enough to make much difference. Better off just getting a better fan.
