hi, i just checked my pc after about a week and it seemed overly dustly, like a visible layer. i have an nzxt h5 flow with 6 120mm nzxt fans. any ideas to try and make this better?

Kind of a multipart answer, if you will, but questions I would ask is where is the computer located in the room (desk/floor). How is the flow direction set up and on your intake fans, do they have a filter?
having filters on all of your intake fans will help lower dust within your case but if the room/area you live in is just naturally dusty, you'll just have to keep up on maintenance

you should setup your fans so you create positive pression inside, and the intake fans must have filters

Well balanced intake and outtake
But dust fans are a must 
Also just weekly vacuuming helps allot
Less dust in general means less dust in the pc

That's your problem - you may seem to have your PC in a balanced airflow, but you didn't account for the fact that your intakes, which has dust filters, has much higher impedance to said airflow compared to the exhaust fans. This means overall airflow from intake is lesser than exhaust, creating a negative pressure case interior, and that's where all the dust is coming from.
There are 3 solutions to this problem:
- Remove 1 exhaust fan
- Add 1 intake fan
- Change the fan RPM profile so that the intake fans are faster at any given temperature than exhaust
basically, you want to make sure that there is more intake CFM than exhaust, accounting for all losses from filters and other obstacles.
A good way to see if this works is just checking if your dust is mainly on the filters rather than coming in elsewhere - that means your case is slightly positive in pressure
