Martin,
Sorry to go off topic, but are you going to be making a board for the Hashfast chips? I noticed they were selling hem on the web today.
From Hashfast:
The Golden Nonce Chip is a leading-edge Bitcoin mining ASIC with 800 GH/s performance and low (best-in-class) power consumption.
Golden Nonce ASIC Chip Highlights:
High performance 28nm ASIC mining chip
Hashing Output: Up to 800 GH/s (overclocked)
Interesting, http://hashfast.com/shop/chipsales/ but I'm really looking forward to hear about plans for Bitfury 2, I did hear a rumor test chips would be available end of February? I'm saving up my Bitcoins for Marto's next creation!  |

Is there someone that have replaced the noisy fan and running stable @260/1000 ?

Impossible! But does depend if you win the silicon lottery, I see there are some more efficient A1 chips out there, and how cold your room is. Best I've seen on the pre-production lot was someone running 230/950 with more quiet fans blowing down the sides. It would need a larger heatsink area, if only I could get a 3rd fan on top! That industrial heatsink is made more for durability than surface area, but you could increase surface area by cutting slices across it. There's a flat area under the heatsink (4.8x10cm) where you could attach a CPU/GPU heatsink and 92mm fan or even a water cooling block to a radiator! |

Wow, as this is my only bitcoin mining machine, i will not modify it "too much" until i reach ROI. Changing the fans is a modification i can handle, changing the whole heatsink is too risky for now... Btw it is a very stable machine, running @260/1000 for one week now... And i would like to thanks the whole community here (specially gator and zich), cause they really provide good help. |

Changing the fans is a modification i can handle, changing the whole heatsink is too risky for now... I wasn't saying rip the old heatsink off, just add some more heatsink to the flat space under the original one. Something like this (200x99x45mm) should accommodate another 2x quiet fans and in theory add another 200W of cooling for £25/€30. http://www.ebay.co.uk/itm/271196219864?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649or just be happy when running 215GH/250W @ 220/900 that you're running it at best power efficiency, 0.86GH/W 1.16W/GH in my case. |

I was looking at them today and no indication they were running out. I miss the old system where you could see how many were left in the batch.  |

marto74 is it posible to get my tracking since there is a big chance I will need to redirect it or arrange a pick-up.

NEWS UPDATE: https://bitcointalk.org/index.php?topic=228677.msg5460261#msg5460261Urghh, very disappointing! Still on 55nm node with just a 25% improvement. Hope they can make them cheap or Friedcat's 40nm chips ( https://bitcointalk.org/index.php?topic=438359.0) might just win the cost/efficiency balance battle for $/W/GH per board! |
