I would send them with a speed control

When they run at 3900 rpm or less they are pretty quiet

That would be awesome.  Thanks!

I will pack it up toss in a speed controller

You can run four on the dual 2000/4000 two as push two as pull.

 the fan controller can do four of these

Interesting I wasn't even thinking of a push pull setup with these fan pushing so much cfm.  I was thinking if a pair of the Scythe fans are enough then a pair of these would be plenty cool enough.

it is something to consider.

here are photos
a pcie jack to the controller.  the single wire can handle 100 watts the controller can handle 125 watts the fans can pull 108 watts that would be 3 at 13 volts which is not the goal you could do 3 controllers to 1 pcie jack and run 9 fans as long as you run them at 10 volts or so.



better shot of the pcie cable note the 2  on the right are the scythe fans pushing with one sanyo pulling



here is the voltage step down on a rubber disc note lite means it has power


leads to 3 four pin jacks 1 has a sanyo plugged in



sanyo as the pull note my pipe cleaner attachment system is on the scythe but could add to the sanyo
 i like this push pull setup


volts at 7.24 are pretty quiet I would say running this  at 7 to 8 volts and the two scythe full power sound level stays the same.





last photo is the little volts pot

Philip always come up with the coolest solutions.  I like this FAN controller idea.  The cabling also looks clean too.  

P.S Did the 3D Printed Duct connector I sent to you made it there yet Philip?  USPS isn't exactly the fastest company but it's been a while.  I am sure you will come up with some nice solutions with those as well since Spring is coming up soon.

Just "Mining" my own business.

Hmmm seems like more than I thought it would be.  So without the fan control these things would run at full blast and are probably quite loud.  I'd need the voltage step down and a pair of male pwm connectors to connect the two fans.  Does the step down get warm?  I notice a couple of heat sinks on it.  I would probably want to wrap that up with something.

I got the 3d printed duct connector it seems to restrict air flow and thus fan speeds up.

I only tested the rev 2  avalon6 so far.

I would send you the fans and all wires even a rubber pad - place to set the controller.

So you could run up to 3 of the faster fans.  you would get it in plug n play condition. you just need tie off cables to your liking.


new photos on the way

11.76 volts into note new rubber pad.


 
7.24 volts out all rubber pad and rubber band mount the controller to be shock resistant.

it won't over heat unless you plug in 3 fans and max volts in a very warm room.  Set at 7.24 volts it should be fine.

to test it I will unplug the scythe fans and plug all three into the controller . I will run over night at 7.24 volts.



the sanyo at  7,25 volts with the two scythes at 11.76 volts (low power psu setting) sound is 57 db


all three fans at 7.24 volts 52 db

Thanks Phil you're awesome!

check sound photos  above.

I will run the 2 scythe with the one sanyo for a few hours  and check for over heating at 7.24 volts and at 8 volts.

these fans from sanyo have a clip tab
see the tab




once clicked you can not open it




if you pull this you will break wires




this screwdriver allows fan removal
this screwdriiver allows fan speed adjustment on the drok step down /fan controller





this is the perfect tool a small screwdriver and I put it in generalalt's kit

I just got back from post office so you should get them on weds. maybe.

And I ran the controller overnite at volts of 7.24  driving the 1 sanyo and the 2 scythe fans.  no over heating

update

I no longer recommend the 2880 breakout board for use with Avalon 6

the avalon 6's where running 2 per psus which is about 2100 watts dc/2300 watts ac

not over volted

I had some warmer weather last week and the board jacks over heated.

https://bitcointalk.org/index.php?topic=1403986.0



see jacks in these photos


















I am cooling the jacks with 3  fans and now using the top row of the jacks note these are hi end 15 awg pcie cables

all issues appear on the breakout board jacks not the avalon jacks.

read here

https://bitcointalk.org/index.php?topic=1403986.0


So what is the cure for this?  I have purchased this product


http://www.lemproducts.com/product/dehydrator-screen-material/food-dehydrator

and use this controller
it runs 3 fans fine


http://www.ebay.com/itm/DC-12V-PWM-PC-CPU-Fan-Temperature-Control-Speed-Controller-CPU-High-Temp-Alarm-/131557958526?




let me show a few photos

three fans drag hot air away from the jacks








see jacks in this photo
