fan cfm

Generally speaking (but not always) the larger the fan is the slower it needs to spin to push the same amount of air. This means that if they are decent quality fans then they will run quieter than their smaller counterparts.

 

If possible look for larger fans that have variable speed (either through PWM or a fan controller) so you can vary the CFM, speed and volume of them to your liking.

which is better using a 120mm fan with high speed or a 200mm fan with low speed both of them have the same cfm 

 

Depends on your need. I prefer 120s, you usually can fit 2 of them in the same size as a 200.

The projects never end in my line of work.

what about 120 and 140 with the same cfm

 

Again, depends on your needs. Where are they going?

side panel they will be for intake 

 

What case? I have a 500R with 2x 120s in that. The difference is little to none.
