hi guys, need few advice here, i hv corsair 650d all stock fans (2x20cm front n top, 1x12cm rear). i hv cm212+ stock fan and hd 6950 ref gc.
i very much like to address the noise level down a bit and thinking or changing the 212+ stock fan, as i think it gives some louder noise than the other fans. some folks here sell arctic f12 and one person sell gelid wing 12, which is good to replace the stock with price consideration ofcoz .

another thing, r the corsair 20cm stock fan good performance/noise wise? cos i know jack about fans (bought the case cos it look good)

so, how do i turn down the noise

the case got fan switch but i think the woosh sound is bit loud especially im 2ft away from the case. that 20cm is working i guess:)
yep im thinking of f12 too for the 212+, not gelid aa?
