Hi i just ordered a hyper 212+ for my i7-920 build, just gonna oc to 3.2 so no need for anything better, but my question is that i have a coolermaster silent 120mm fan from a friend i think its 1200rpm and 44cfm and i don't know if i will gain anything using that as a second fan for push/pull and if i do should it be pulling or pushing, thnx
