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.

Great! Thank you!

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.

Here's the link if anyone is interested:

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:

You see the watts consumption @ 60 watts when at full throttle with 5,500 RPM's:  https://www.youtube.com/watch?v=__MhqY1zPK8

You see a 3 wire in 4-pin version of this fan [They took out one wire] turning the blades of another fan in this video:  https://www.youtube.com/watch?v=Wqc72EOuteU

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

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.

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

Interesting, this is the 1st time ive seen that heatsink.  i have 4 s5's with the older style.  Has anyone compared the temp at higher clockrates with the new heatsink??


Thanks

not sure 70cfm is enough..

i was thinking maybe a couple of these.

http://www.newegg.com/Product/Product.aspx?Item=N82E16835103193

i have these in my case and i can for sure tell you they flow a lot of air.. they dont have a high pitch whine to them either.
or maybe these
http://www.newegg.com/Product/Product.aspx?Item=N82E16835132026

im going to wait till summer time tho to mess with the fans.. i dont want to void the warranty.

this would probably be a good pull fan

That would be nice if they include the VAT / import duty payments and the courier charges in the shipping cost to the UK, so all we are left with is signing for the item on delivery.

PS. Where did you see that quotation?
