After speaking with an expert the following fans are in stock:
"NF-P12 PWM" $19.09 USD each.
http://www.noctua.at/main.php?show=productview&products_id=43&lng=en
At 70 CFM each two of these should work to keep it under 50 deg at stock frequency (350M) or higher.
$38.18 total.
I've also come up with two budget options:
Dual Cooler Master:
"Cooler Master Blade Master 120 Black 120mm PWM Case Fan 600-2000RPM 21.2-76.8CFM / R4-BMBS-20PK-R0" $11.91 USD each.
$23.82 total.
Cooler Master / Arctic Cooling combo:
"Arctic Cooling Arctic F12 Pro PWM 120mm Fan 400-1500RPM 57CFM FDB / AFACO-12PP0-GBA01" $4.77 USD each (can only push air due to design limitations).
$16.68 total.

What's the minimum per fan CFM on a 2x fan setup?
I'm able to run at a frequency of 250M hashing almost 800GH/s with two old PSU fans. These fans can't be more than 20 CFM each. This thing seems stable just below 50 deg.
If you want to run it at default freq (350) you need minimum 200 cfm in my opinion.
Something like 2 120 cfm fan using a push pull setup should work.
Be sure to be below 60 on each blade.
Why not use only one 256 CFM fan @ 5,500 RPM's that I suggested earlier?
I see [now] I need to go ahead and shut down an S5 to take the time to replace the stock fan with the one I mentioned and post pics of the ambient temperature on my thermometer; as well as screen shot of miner stats.
I have purchased eight [8] of these fans in total from the same seller on Amazon: Delta Electronics PFC1212DE 120x120x38mm Cooling Fan, 252.85 CFM, 5500 RPM, 66.5 dBA, 4.8 Amp, PWM Connector (4-pin). It is $27.00 with free shipping. You do not have to be a Prime member to get free shipping on this one. The seller is selling this through Amazon. I'm sure they have already added shipping to the price. It's worth it to me to pay $7.00 more for a great quality fan with lots of CFM. This thing is a beast!
I use this fan as a replacement on my S4's and S5's. I plan to replace the stock fans on the SP20's with this fan as well after the warranty period is over. This is what you need when replacing fans for the SP20:

Fan speed gives a competitive edge as a banshee screeching contestant and at 5,500 RPM she looks like a winner.

I'm personally liquidating all of my Antminer S5 Batch 3 Units. My lease is up - and it's simply too much work to move my business and all the rigs.

Write me please EU service center contact to speed up my defective blades problem resolving...
Thank you!
Thank you!
also, for the dead S5 or defective S5, turn around time via US/EU service center is as usual in just a few days.

Great! Thank you!

With the open style of the s5, can you have a push/push or pull/pull setup? Or would that be to much? I ended up ordering another Delta fan off of Ebay $20. I unplugged the stock fan, and the temps went up to 58/63. Still not bad, but I like to be under 60. This is at stock setting, also.
Pull pull wouldn't work as its too open, push push would be interested but will likely have a large deadspot in the middle which might not come up on the temps. Stick with push pull if you can.

Once the batch 5 is sold out, batch 6 in June 9th is the only S5...
Please wait for the official announcement for the next available miners.

i would love to buy it but i have a feeling it will consume too much electricity from where i am. i have tried an online calculator. will breakeven in 3months or something, making maybe another version of the product to come out. i guess i will stay on this thread and once the next one is out, kindly let me know . i dont know if you have a customer list or something
April 02, 2015, 01:31:33 PM
Interesting. Batch Five is now sold out.
yep, they are probably massively producing it and hashing in their new hosting center.
good for sellers in the aftermarket

If you want to run it at default freq (350) you need minimum 200 cfm in my opinion.

Be sure to be below 60 on each blade.
I am running a 113 CFM fan (Delta AFB1212SH) in push at 350 with temp only 61/57 when ambient is at 30C. I am sure miner temp would be even lower at lower ambient. I might try push pull or leave it as is since I am very satisfied with much lower noise. See my detailed post a page or two above.
BTW, it is a legend that you need to be below 60C, stably below 65 is fine-I run S5 like this (at 58-62C) for months before using Noctua.
AFB1212SH is 40% of the Noctua price.

Received 3 miners. 2 blades are broken...

One of two blades have burned chip place...
I am doing LEGO 2 days in a row and its very bad for my nervous system.
BITMAIN, PLEASE SEND ME REPLACEMENT LIKE YOU DID WITH FAN, 4 DAYS AND I RECEIVED IT....

I see that you guys have the "newer" heatsink. I was given the heatsink similar to the S3s.
