So, I have a Thermaltake A60 case. I want to add more fans because i have the original ones which creat negative air pressure ( 2 exhausting 1 intake). Should i had 2 more intakes ( 3 intakes 2 exhaust) or make a neutral pressure (3 intake 3 exhaust)? (and if positive pressure is better than neutral why?)

Another question, When i add a fan to the side, i won't have a dust filter. Should i get/make one?
i heard that they reduce airflow.
The 2 front fans already have the dust filter of the case.

My idea is, 2 intake on the front with case dust filter / 1 intake side fan with no dust filter / 1 exhaust on top (no dust filter) / 1 exhaust on the back (no dust filter), what you think?

Thanks.

I always follow the front/bottom intake and back/top exhaust. If you need dust filter there is a silverstone dust filter that can also make your fan perform similarly to their AP fans.

You can add a side fan without a filter, just make sure you regularly go into your rig with a can of compressed air and clean everything out. Even with filters, this needs to be done at least yearly. The filters reduce dust and dirt but they don't eliminate it.

Remember that dust filters don't really affect airflow amounts ASSUMING YOU KEEP THEM CLEAN! Dirty filters equals no air.
