For those of you planning a cooling/fan/enclosure system - BitFury reports that the chips have an optimal operating temperature range of 45C - 50C measured on the package. Cool them too much and they actually don't perform as well.

Wow thats kind of dissapointing, I was hoping to chuck them outside for the winter. Does the default hardware and/or software allow any overclocking to compensate ? |

I believe the default hardware is limited by a 30A regulator (or some electrical engineering thingamajig). There is quite a discussion about it when c-scape demonstrated their S-Hash card (which has the higher power capacity). If you search in the forum (and this thread), you will find more info about it. Here is one link: https://bitcointalk.org/index.php?topic=251966.msg2797461;topicseen#msg2797461tl;dr: Boards designed for stable environment of 100TH mine. No overclocking without extensive manual reflowing the components on the boards (200+ per board?) |

For those of you planning heatsinks, Intron provides a good reference. http://imgur.com/gUMVK0bPS: You are looking thru the board from the top side. Don't make the 'mirror error' too often made:) --Intron Hi Dave, I know this is an old post, but just needed to confirm something: the image at the link you included above shows 6 mounting holes on the PCB whereas the PCB in the picture in this link https://bitcointalk.org/index.php?topic=251966.msg2676985#msg2676985 seems to have none. Which is accurate? I assume that the photograph is of a prototype PCB which predated the mounting holes, but I'd like to know for sure. Thanks. Yes, that was the very first prototype board, only a very few were made. Later H-CARDs have mounting holes. intron |

were made. Later H-CARDs have mounting holes.
In fact, only the very first two cards were ordered without mounting holes. |
Happy with your c-scape product ? Consider a tip: 16X2FWVRz6UzPWsu4WjKBMJatR7UvyKzcy

Keep in mind that putting them out in -5C weather doesn't make the chips run at -5C. They're still generating heat... |

Do you think we need an enclosure of some kind for heat management or will we get by just fine without one? I was planning on just sitting a fan next to it, should it be needed. |

Stick the test unit in one of these so we can see what it looks like...

This is all Tytus is doing and its working fine, but yes you will want a bit of air movement. If you clock it up a bit in software, you'll definitely need fans... Wha?! I let something slip?! |

I really hope someone constructs a little cheap Bitfury powered ASIC, c'mon let us "less fortunate" people get some proper stuff! Im sick of running my screaming gpus for ~1gh

Intron is designing a two-chip USB miner - he posted on Bitfury's thread: https://bitcointalk.org/index.php?topic=228677.0Surely someone will make these when the design is done... |
