(1)200mm or (2)120mm

[XTO --]

I've recently built my PC on a HAF 922, it has a 200mm frontal fan, 200mm top fan and a 120mm rear fan. It also got a 200mm side slot, where i can put 2 120mm if i want. Since there's nothing there yet, i'd like to know what would keep my temps lower, two 120mm or one 200mm fan thanks

The bigger the fan the more air it moves which means lower fans needs higher speeds to keep up and make more noise.
With 2x120mm's you'd get just about the same airflow but you'll also have two fans giving out 20dbA instead off one.
So since the airflow is about the same and two 120mm's would be twice as loud I recommend a single 200mm.

Okay, thanks daffy

Someone else told me the same, although there's nowhere near my home/city that sells 200mm, i think i'll just have to buy somewhere else

It's true that there aren't many 200+mm fans on the market, but Xigmatek has quite a nice lineup. Check out the Xigmatek XLF-2004.
