The pc shop that assemble my pc put the radiator in front (400c casing) and put exhaust fans rather than intake fans and the top and back fans are exhaust. Is this setup of fans good? or bad? I live in Philippines and my place is kinda dusty.
Assuming the Corsair Carbide 400C the recomendation from Corsair themselves is to have the cooler mounted in the front as intake with everything else exhaust.
In a truly dusty environment I would flip the whole thing around and have the Radiator as exhaust and have all filtered intakes. Sadly the H110 is a 280mm radiator, and wouldn't fit in the top of the case.
Only reasonable option would be to turn your top and rear fans into intakes and make sure they are filtered.

I have the Corsair H110i and I have it set to intake from the top of my case. I run an overclocked i5 6600k at 4.8Ghz and under full load my CPU rarely reaches past 70. However fans are not specific to exhaust or intake. They can be flipped. Id recommend bench-marking your system under worst case scenario using prime95 under both the current setup you have and then flipping the radiator fans to intake and running the test again. If i'm correct your temperatures shouldn't change much. But they may improve in the intake position rather then exhaust.
