they will work with an underclock . not with stock speeds or an overclock. Because of the cfm ?? yeah most of the ones that work at freq 350 are cfm of 140 or more @topek those 4 pin delta's should work in a push pull

I have them in a isolated basement ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) cool ty i just bought one of these to i gonna test it, i read some place if you use this one with just one 3 pin plug it can be controlled by a fan controller while the other, same one with 3-4 plug can't be unless you mod it all most same price gonna see. http://www.amazon.com/gp/product/B00CIB9BTU/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1there we go Connector : 4 pin male molex and 3 pin female.There is a 4-pin molex power connector and a 3-pin TAC connector. The 4-pin molex power connects to a power supply and the 3-pin connects to a 3-pin header. You won't be able to use a fan controller to control the speed of this fan. If you want to be able to use this fan with a fan controller, please purchase the same fan with only the 3-pin TAC connector That is this fan for 4 bucks less im just testing things so i know what way to go for me . http://www.amazon.com/Delta-Electronics-AFB1212SHE-CF00-120x120x38mm-connector/dp/B004XJLOG8/ref=pd_cp_pc_0

I can't imagine a room of 20 or more of them clocked to freq 375.

I love the fact that Bitmain always comes through with product and is always working on a new product just as they are releasing one. I have always believed in home mining and am addicted to it's nature. But truth be told hardware in the last year hasn't seemed to make the significant leap to pull ahead of the difficulty. Yes, we can all buy the latest and sell in 2 to 3 months and buy the new hardware. This just seems to benefit the manufacturers since they always have the hobbyist willing to buy. I wish from a hobby only standpoint I could keep miners running, but I usually don't have the overhead for electric costs vs just buying btc outright.
Short story Long, just wish Bitmain could step ahead of the minimal gains in new hardware only to be obsolete next month. I know this is the way it just is, but can't help think they're r&d has the funds to really help the home miner and the decentrilization.

I have two deltas similar to the ones you have on an S5 that runs very quite. There is a link to a video here it has 15 seconds of SP20s and 15 seconds of the S5. Not a very scientific approach but a quick and dirty comparison: https://bitcointalk.org/index.php?topic=902305.1240. I like both unit types as they both serve me well.

what is your power cost? It's low compared to everywhere else at $.09 kwh but running 7 - 8 S3+'s with btc being low made it tough to keep going. S1's faired better at the start of last year. Just trying to keep the btc mined without trading it in to pay expenses. I don't mind paying additional $250 or $300 in pud costs but why when you mine less than that in btc.

I don't mind paying additional $250 or $300 in pud costs but why when you mine less than that in btc. get some S5 sell off the S3 it will be i was talking to some one from Canada he ( hes a home miner ) told me he has to upgrade to S5 from S3 the power is not worth it any more with S 3 and 8 S5 should give you 901.13 $ A month before deductions and Next Difficulty [estimated] @ 835.69 $ at stock speeds if did the math right . at 9 cents per KW it wont go that much higher .but i wish the Miner would last a little longer may be 7 to 9 month over 3 go try alt coins its worse im glad there is a company out there like bit main. most the lite coin miner are way worse and very little of them beyond KNC i have nothing good to say about them . and A2. I know one or two who mine and pay there power cost each month with the sell of bitcoins they told me it works out for them that way no real money out of there packets they said they are still able to keep a nice amount of BTC on hand even after paying there power cost each month

You're cables and PCI-e connector will melt! Max 250 watt per cable, less if you use flatcables. With the S3 yes, with the S5 NO!!!

So I think I found a solution to the high pitch whine of the stock fans. We all know the guide vanes are what's causing the pitch. I received a fan with a broken blade on my my batch 1 S5's and Bitmain was kind enough to ship me a new one. I decided to do a little experiment today to see if reducing the number of vanes would change the pitch, which for my ears (healthy 35 year old) now sounds more like a S3. You notice on the vane there is a thicker part on the outer edge, I took some wire cutters and cut every other vane right where the thin part of the vane meets the thicker part (careful to line up the fan blades so you don't accidentally cut one). I then used my thumb and as close to center as possible I just pushed down on the cut vane and it popped right off. Note that the power wires run down one vane so you probably will want to start there and you'll still end up with an odd number of cuts. Here's a picture and for those brave enough to try it, let us know your results. My temps are exactly the same and I do use a high cfm pull fans as well. Still experimenting with those, so far the Silverstone Tek 140mm x 38mm Fan seems to be giving me the lowest temps but these S5's seem to run in all different temperature ranges so it's all subjective. https://farm8.staticflickr.com/7515/16089177837_65df09d9d5.jpg

As a completely different question coins are now 223 usd. next diff may drop back under 39. It looks more and more like s-5's or sp20s are a home miners only chance . I get an s-5 tommorrow I will post shots of it with modded delta fans. this will bring me up to 8 sp20's and 1 s-5 I may buy another s-5 but with this drop in coins it is very tough to do.

If that will not be satisfactory, there's always the Delta fan option. I'm glad to know that it did make a difference.

The vanes do make a big difference in channeling the air down the center and across the heat sinks. I have higher CFM and higher pressure fans that should in theory cool the S5 down better but without those vanes to center the air they aren't as efficient and my temps get dangerously high. Unfortunately we're stuck with the stock fans or Delta's, for us home miners that don't have climate control.

I use Noctua 3000-great for 325mhz/1070Gh and much much less noise or Noctua/Scythe combo-OK for 1100 Gh at one step up from 325 (331 something?).
