The most powerful 12V/loudest fans..........

[Zclyh3]

In terms of 80mm:

Delta FFB0812EHE

12 volts
0.9 AMPS
5700 RPM
80.16 CFM
52.5 dBa

Now that's massive power!

Now for the 92mm:

Delta FFB0912EHE

12 volts
1 AMP
4800 RPM
110.18 CFM
55 dBa

I'm currently running 5 Panaflo U1A's at 46.9 CFM. I shouldn't have bought these...should have gotten the ones above. Super power!

Well..there goes my data..can anyone provide me with a more powerful fan?

bah.. that's nothing man.. snag yourself a 172mm fan.. You can get ones that are

172mm x 150mm x 51mm
230CFM
55db-A
25Watts
2.26amps
3500RPM

Metal blades...

THAT'S a fan... you get double the CFM of that 92mm delta at the same noise level.
The fan has feathered blades.. It will most likely chop up anything you stick in it...

how about car radiator fans

 

[Zclyh3]

Well...I was considering the COMPUTER FANS that are between 80mm-120mm.

Delta FFB0812EHE (The world's most powerful 80mm fan)
Delta FFB0912EHE (The world's most powerful 92mm fan)

I don't know about 120mm.

But after reading some reports, the above fans are the most powerful right now.

Are you just looking for loud, powerful fans for the heck of it, or do you expect to get some meaningful benefit from them? Dunno if another 40MHz on your overclock is going to justify the money...

If you do want a powerful fan, you should look at centrifugal blowers. Upwards of 300cfm in a blower that would fit on a PAL8045 with some adaptation. Browse around digikey.com.

Wow...300 CFM..super power!

If you really want "power", why not try watercooling or liquid nitrogen stuff.

5200 CFM of 12V action baybee!
