Perfect CFM Matching = Best Airflow and Pressure?

post #1 of 5
Thread Starter 
I'm wondering about this cuz I'm going to set up two tricool intakes @ 56 cfm each.

Intake - 112cfm

one tricool exhaust @ 39cfm + one big boy exhaust @ 82cfm.

Exhaust - 121cfm

I do understand that I'll be slightly negative pressure but this is the best I can do with the fans I have. I refuse to run the intake any higher cuz it'll be too loud...

Also my case is a P180 mini. So is my case better for negative or positive pressure?

I don't think any case is perfectly sealed, there are a lot of place where the air can get in.

Your set-up will be fine...

You can use a fan controller and set the exhaust fan in lower speed...

Remember fans with filters blow less air than the specs, since they're tested at FREE air enviroment.

So those 112 CFM's substract atleast 20%.

nooo... i guess my computer is going to be running at negative pressure. anything above medium gets way too loud for my tastes...

btw i added the two intakes and my temps haven't done much. only thing about it is it looks better.
