That 76cfm would be the max amount of air it can move.
IF the system is controlling the fan speed, it would move much less air at idle.

will it remain at 76cfm or when it,ll be at idle it will lower its speed and rpm andd how much %age?

When the fan is spinning slower, it is moving less air. Less cfm.

You're overthinking this and getting hung up on a number that really means little.
You've chosen a good fan.

Buy it.
Install it.
Love it.

yo thanks man.. but can you tell me which will the better from these two cases:
1)corsair carbide 100r S.E

a case fan with 72CFM @23dB(A) is pretty bad if it's over 10$

see if you can pick up a Phanteks F140SP, 82.1 CFM @19 dB(A) or a Noctua NF-A14 FLX (similar to the Phanteks)
