Need help with fan configuration in Xigmatek Elysiulm with rads.

Hi guys,

I need some advice on the fan setup in my Xigmatek Elysium as it gets very dusty very quickly.

I have 4 intake and 4 exhaust fans. 3 of the intake fans are on the front of the case but 2 of them are mounted to a radiator, the last one is mounted to the side window.
Then there is 1 exhaust fan on the rear of the case and the other 3 are mounted to another radiator in the roof of the case.

I can't remember if its better to have negative or positive pressure to reduce dust but I don't see how I could achieve either of them.

Anyone got any ideas?

The case has fan filters but im guessing that the rad on the front of the case will be blocking a lot of the flow from 2 of the fans.
The fan that's at bottom has no restrictions but is spinning at its slowest possible speed so i will increase the rpm on all 3 front fans and see if that helps.
