I am somewhat dissappointed in this fan. It is kinda noisy although Its noise rating is 20dB which is much less than many other fans with similar CFM rating.
Do any of you know of a silent 12V DC fan (120mm CPU fan)? I'd like to replace it if possible.
Air flow wise, it's not bad, but it's no comparison to a 6 inch fan. I wonder how many fans I should use for 180. I currently have two mounted on the canopy. I hope to add a fan or two over my sump.
