Xigmatek XLF-F1253 vs Cooler Master R4-L2R-20CG-GP Need advise on which 120mm fans to pick for better cooling and faster/stronger air flow + durability fitting onto my Cooler Master HAF 932. Cooler Master seems to have a faster Speed (R.P.M.) @ 2000 RPM with Air Flow (CFM) @ 90 CFM while Xigmatek having a Speed (R.P.M.) @ 1500 RPM with Air Flow (CFM) 61 CFM. Wana get to know more about these two + your recommendations. Thank you so much!
