I just got my A14's yesterday. They are quieter than my coolermaster nepton 140XL jetflo 140's that came with it, they were louder.
But, i'm running a push pull on the RAD. as you can see in my avatar 1 fan is on top, so I can hear this high pitched humming that kinda annoying, but I want the cooling power of 1500 RPM. Do I need to put the low noise adapter on the top fan or bottom one or both to lower the sound?
Thats the only negative for these, the high pitched whining horizontally mounted on a rad, push-pull.
One positive thing is that they actually have nice static pressure that they dont lie about, the coolermaster top fan blew to the sides, while the with the A14's the air blows straight up.
These fans are so good that I want to put more in my case, yet the whining is killing me, ugh, I want LED fans tho, any 140mm fan with LED's (Blue) comparable to the noctuas? they will go on the sides and front intakes.
