If anyone's interested, I hope to be testing a custom 30mm high performance fan producing >=6.5 Cfm soon.
(That should be 18% more airflow than the Yeah Racing Tornado)

i would take a look at this fan:
http://www.rc-mushroom.com/product_i...0x10mm-p-26161

really good price

im using the 40mm crazyfan now and its really impressive (used the 30mm tornado before and the 40mm fan makes quite a big difference)

The side piece racing fans are the best IMO.

For a 25mm fan nothing beats the Side piece racing fans. If you want a 30mm fan that you can wire directly to a speedo (battery) nothing beats the fans that Superior hobbies has. Its like a tornado in your car. Ive not had a fan move that much air before. I believe he said it was 12-15 cfm's but I cant remember exactly....it is bigger and heavier though than the Side Piece racing fans that work awesome for ones plugged into a receiver. It moves more air off of 5 volts than most do off of 8.4 volts except the superior hobbies fan.

Awesome, thanks! I've been looking for that one since Knapp came back from Snowbirds. He couldn't remember who he got it from.

It is interesting that the superior fan is 3 wire. Which ones do you wire up?

Red and black. Cut the yellow off. It moves a lot of air but its also a LOT bigger than your fans and has to run off the speedo to move that much air. For size and simplicity your fan works just as good I think. Motor temps were the same when using both which tells me that yours is plenty of air across the motor.

Out of curiosity,

How are you guys testing/measuring the CFMs or comparing between fans??

I haven't tested anything yet, I'm going by manufacturers specs.
I think the Zeppin and Superior Hobbies fans are 'creatively' specced though

The Superior hobbies fan blows the most air by my unscientific hand in front of the fan check.

I cant speak on the Zeppin as Ive never seen one but....

Have you felt the air off of the Superior hobbies fan? If not then there is no way for you to know if it is "creatively" specced or not.

Ive used a LOT of fans during my years of racing and I have not had one from anyone blow as much air as this thing. Granted it is probably over kill but it works great.

How many Revtechs have you seen come off the track after a 6 minute race on super high bite carpet at 95 degrees? Probably not a lot!

For $30, it better bring that motor to sub-zero levels. Thanks for the info EA.

That's why I said "I think", not "I know" I'm just saying that compared to all the specs for 5v/6v fans of manufacturer datasheets I've seen these jump out a lot.
These datasheets also specify static pressure / airflow curves, not just a single number.
"it felt like it moved a lot of air" isn't really a precise CFM measurement either. I don't think many people would know how much CFM a fan moves just by feeling it with their hand, or by comparing it to a very low airflow CFM.

Do you happen to know of a manufacturer (not a hobby reseller) that makes fans with these specs ?
