Case fans

[lilhippo9]

im wondering about my case fan management. is it a good set up to have two intake fans one in the front and one on the side. and 3 exhaust fans pulling air out. my case is a Rosewill challenger

i started out with two intakes but my case got really dusty so should i have the two on the side as intake or both as exhaust? or mix it up

Generally you want front and side as intake fans and rear and roof as exhaust fans.

As for dust, it doesn't really matter what fan configuration your running, dust is always going to gather inside and out. Id recommend having a look on eBay or somewhere similar for "dust filters". You can often buy a big sheet and just cut out 120x120mm pieces and attach it between the case and the fan which will stop dust being drawn inside Takes a little "custom" work, but its worth it.
