@pekatete, dead fan, we do offer replacement. The fans used on Antminer is not an easy one to find as it uses 4 wires and high RPM. We are sorry for the inconvenience. Our USA based team can take care of you faster usually and they are available 24/7. Thank you for the stats!!
52 is a bit warm but it is well in the range.
Not sure you are thanking me, but I'll accept anyway; You are welcome. The 52 refered to is the top temp, i.e with that configuration, the temps never go above 52 during the day (and currently below 48 at night). I actually believed 52 was a brilliant top temp, but I've not had a different temp to compare with as my S5 shipped with a stone dead fan that never turned a fin in anger! I was advised to buy one from the local market (without any hint of irony or any offer for a replacement .... not even a voucher offer!). Better late than never .... but I am not based in the US, rather the UK, so it may be tricky for me to send you the dead fan (which I still have and looks pristine next to the others I salvaged from my now decomisioned S1's!). If on the other hand you can send me the replacement without me having to meet the cost of mailing you the dead one, I'll be more than happy to furnish any info you require. |

@Pekatete, if your purcahse was within the last 90-days, please e-mail support@bitmain.zendesk.com and attach your Order Confirmation page in PDF with your shipping address information.

There is a service center in Serbia that may be able to service you closer than USA. It is just inside 90 days, so I'll send an email to the above address and see what comes of it. Not sure what the wording should be in the email though (seeing it was info@bitmaintech.com who told me to get one from the local market) .... I'd like to get a replacement fan as the shipped one was a DOA .... would that suffice? |

I've done some research, made some measurements and experimented with some 2-wire 120mm fans from old PSUs. I believe that two of the following fans will work in push/pull configuration to run at stock frequency (350M) or higher without going for gold in a banshee screeching contest. http://www.cougargaming.com/products/fans/vortex_pwm.html"Cougar Vortex" $11.89 USD each at the local shop. |

Not enough CFM. These fans do max 70 cfm. ( I did try the same setup) You need more cfm. Check the delta fans.  |

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. |

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

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.

Would a Silverstone 1500W Power Supply be a good option to run 2x S5's?

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. |

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. |

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. also, for the dead S5 or defective S5, turn around time via US/EU service center is as usual in just a few days. @BitMainWarranty, do you folks plan to offer more of the S5 before June 30th?
