Question Highest CFM Fans at 120mm and 140mm

[unseengundam101]

I am looking for the highest CFM fans in the 120mm and 140mm sizes.

So far this what I found on Amazon:
Ultra Strong - 200 CFM 120mm fan
Bgears b-Blaster - 308 CFM, 140mm fan

Are the best CFM I can get? Any other choices out there?

That's about what they top out at in those sizes.

You do know they will sound like a vacuum cleaner running right? Noctua (Industrial line) has fans that are similar in CFM performance to the ones you already found, and they output 41+ dBA. The "Ultra Strong" one above is rated at 59 dBA, while I didn't see a noise rating for the Bgears model.

You might already know about the noise aspect and that's what you want, but I just wanted to point out the noise these things will output.

241CFM, 120mm

I'm not judging. Maybe you're building a server that you'll keep in the basement.

But just in case this is meant to be in a PC, in your home... Seriously think about it for a bit longer.

Two of these:

AFB1212HHE

www.delta-fan.com

120CFM, 38mm thick, 5.5W power consumption, 44dB.
2x44dB = 47dB

vs a single 241CFM one from the first link:
30W and 62dB

62dB is something you expect from a vacuum cleaner. Or when you drive at 140km/h in a car with poor soundproofing and people inside start to shout to each other.
