Hi guys I just got the Corsair sp 120 quiet edition 120mm fan to replace my antech kuhler h2o 620 stock fan, What's bothering me is I can't barely feel the air blowing even if my hands are like an inch away. SP 120 and stock fan rpm showing as 1490rpm in Speedfan but the stock fan I can feel so much more air blowing than the SP 120. My radiator air used to be cool with the stock fan while gaming and now with the SP 120 the radiator air is hot. What am I missing here?
Corsair sp 120 quiet edition 120mm fan barely feel air blowing

I never knew about CFM. "CFM = how far the air can go" right?. First time buying fan here sorry for being a noob. I thought the air can travel the same distance based on the RPM, so this is not the case?. Interesting that both fan spin same speed but yet the SP 120 quiet edition air doesn't travel as far. So tell me now, how is the SP 120 quiet edition fan good for radiator if it can't push hot air far out and causing my radiator to stay hot?

CFM = Cubic Feet per Minute. It is a measurement of the volume of air that will be moved by the fan every minute it is running at full RPM. Some fans' blades are designed to move lots of air and the result is more turbulence. More turbulence = more noise (all else being equal). Some fans' blades are designed to move air as quietly as possible, at the loss of some CFM.
I would suspect the fan that came with the kuhler h2o was engineered to move the necessary volume of air needed to cool the radiator, while keeping the decibels to a comfortable level. Changing fans from the original design or specs can result in a loss of performance. The fan you chose is actually a "case" fan, not really designed for radiator cooling. They need high static pressure to force air thru the radiator grid.

well as you can see here's the Overview. I believed it since it say so much on how good it is for radiator and heatsink. I also see a lot of people said to use this fan for their radiator too.
Improved heatsink and radiator performance with less noise.
The advanced design of the SP120 provides the higher static pressure that radiators and heatsinks demand, while maintaining a quiet noise profile. Seven ultra-wide, custom-molded blades deliver high static pressure, and the customized fan enclosure helps airflow move in the right direction. The rubber mounts and the advanced hydraulic bearing system combine high reliability with low-noise operation.
High Static Pressure for Efficient Cooling on Radiators or Heatsinks
Cooling today’s high-performance PCs is a complex task, and a single fan design can’t meet every need. The fan you use to exhaust hot air out of your case might not be the best fan to mount flush against a heatsink or radiator.
Static pressure is the measure of how well a fan can push air in this type of highly restrictive environment, and this is where the SP120 excels. It’s an ideal solution for radiator and heatsink use, as well as drive bay intakes, and other locations where you’re mounting a fan directly adjacent to a heat source.
