hey guys. i know my question is about air cooling, but its relating to my water setup so sorry if this is still in the wrong section. basically im half way through getting my new water setup, consisting mostly of XSPC parts. my radiator is the RS360 which will go nicely on the back of my Armour case. i now need to decide what fans are best to put on the radiator. the 360 obviously refers to the 360mm of space for 3 x 120mm fans.. i was gonna get 3 Noctua SF-12s for $25 each from the local shop, but they dont appear to be speed controlled, and their max RPM is 1200. is that enough? i was otherwise considering the ThermalTake Smart Case Fan II which will match my case. or would Antec be a good option also? to help in my decision, linked HERE is a local shop with the most range in fans. the Noctuas arnt there but i can get them elsewhere. cheers in advance.
