Is it the same

[The Astroman]

Is it the same to put two 2500 RPM tuning fans in case and to put one 5000 RPM tuning fan in the same case? 2500+2500= 5000 I know, but I hesitate, all of a sudden.

CFM is more important than RPM. This could be equivalent: 1 x 60 cfm fan or 2 x 30 cfm fans.

yupyup, RPM's are pretty shaky on most case fans. you want intake CFM = outtake CFM for best airflow.

Possible to find two fans that coincidentally occur like that but probably not

Emphasis on COULD ... when you factor in deadzones and stuff, things get different
