Airflow chart recommendations?

post #1 of 16

Due to the closed space, air usually recycles previously exhaust air.

My current setup

Your template looks good, I just ordered a Phantom myself. I'd probably seal off the left panel's mesh though, I really dislike the through and through from the dual 120's. I'm guessing you can't fit the 200mm on the side panel because of the TT Frio?

It's hard to tell what your problem is. How enclosed is the space?

Lets say Its in a corner with the side vents facing the wall, and back facing the other wall, under a desk.

It seems like you have fairly negative pressure. Have I understood so far that your front fan is intake, and you have 5X exhaust fans. Is the PSU intake from internal case air, or from a vent underneath the case?

I personally suggest that you put the two side fans as intake, because you already have quite a few fans in exhaust and intakes here on the side will blow fresh cool air to be exhausted by the top/rear fans. These three total intakes will not move as much air as your exhausts because the flow will be restricted by the close proximity of the GPUs/CPU cooler/hard drive bay respectively. You would still experience overall negative pressure with the front and side fans as intakes if I'm right. Not to mention I just noticed how large those exhaust fans are, the pressure would definitely stay negative but overall airflow would improve from additional intake sources.(IMO)

If you have a radiator up top and you are trying to avoid the GPU/HDD passively heated air try just switching the top side panel fan to intake to boost intake air above the graphics cards(where the radiator fans pull air from) and the bottom side panel exhaust would pull the passively heated front intake air out past the graphics cards.

When you get closer to a balanced pressure setup you will notice your exhausts moving more air(feel with your hand), because they are not all fighting to pull air from the same insufficient intake source.(1 fan and some holes in the case)

Hmm, But I would say the 120mm's are around 50cfm only.

Just make the blocked sides do intake. Give the fans two inches of clearance.

The rest can do exhaust.
