There are quieter fans but they won't have as much pressure. There are fans with more pressure, but they won't be quieter. Which do you want?
Thx for reply, I have a EK PE360 in take in front, pushing with Corsair SP120 high performance.
Only one exhaust at rear also the SP120 high performance.
All the SP120 run from 1500~2100 rpm. Could get a little bit noise. My noctua run at 1200 rpm constant.
The reason why I have this problem is that after I take off the top and front panel of the H440 while prime95, avg temp drops from 85c to 75c and max from 92c to 86c.
My hope is, since I still have room to run push-pull in front, I'll use GT AP-13 or NB eLoop B12-3 pushing, and only enable SP120 pulling when needed. But I have no idea what to do with the top 280mm. I have no room for push-pull at top.
I don't mind either, since I will definitely run them at different speed when needed. If one fan can outperform the Noctua NF-A14 I will consider it.
