Air flow logic confict.

[Ghost]

I have a bit of an airflow logic conflict.

I have a Switch 810 and have notice it is drawing in dust from the cracks. That obviously means low air pressure inside the case. My problem is I have literally no fans to turn around to negate this low air pressure.

Red: Fans

Brown: Radiators

Orange: Water cooling tubing

What would you make the fans?

My current setup:

1 140mm OUT

2 120mm OUT

3 120mm OUT

4 140mm OUT

5 140mm OUT

6 120mm IN

7 120mm IN

8 140mm IN

9 140mm IN

I was thinking about flipping FAN 1, however, that might just make air loop between 1 and 2 and it might just make the system hotter.

Do you think I should flip one of the fans?

You could try for a while with everything taking air in and see how the system fares both with temps and dust?

This isn't like a Lanboy Air. I don't think it would have enough holes in it to be able to push out 9 fans worth of air. The fans and therefor the airflow would slow down. I am thinking of adding a bit of cardboard between the Fan 1 and 2 exhaust side to see how it goes.

I've done a pretty rough setup in a physics sandbox with all the fan speeds the same. You can see roughly that with fan 1 reversed you're going to have a loop and I also just then after reading your idea with the bit of cardboard and tested both inside and out and you still get the exhaust from 2 being drawn in by 1.

Though take these with a grain of salt because they can't factor in what you've got on the side panel if you do..

Are your temps bordering on acceptability? Otherwise just lower exhaust RPMs, or remove #1.

Alternatively, flip it all. Flip everything.

Alternalternatively, what's going on in your drive bays? Could you use three of those for a fan mount?

[Ghost]

I might just remove #1 or lower the speeds. I will try to adjust fan curves on the fans to see if it helps as all my new fans will be PWM.

You could try reversing 4 and 5 to pull air in across the rear rad, and then vent out the top, maybe?
