230 watt vane fan?  I thought the 55 watt one in my aircon moved a lot of air... damn. lolz ... the units pictured are 350 watts !!! I'm going to have to get something of that nature soon as well. I'm looking to add another 2-4 rigs this month and my garage was 101* this morning when I went down there. On that Avocent KVM over IP did you pay for a license for it or get it somewhere else? You can get them super cheap on ebay, but they don't come with the software. |

You can get them super cheap on ebay, but they don't come with the software. This model is the shiz  It comes with software and is awsome... I have 3 of these units and they are still available ... if u can do PS2 connectors then they are the ultimate bargain These are the rolls royce of tech ... they where over 4k in there day... the think with top shelf stuff is that they are always good even when they are 8 years old!! Just liek a BMW ...lolz DatacenterParts the company in the link are fantastic I have been using them for years !! http://www.ebay.com.au/itm/290878446981?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 |

https://i.imgur.com/xxZfMUV.jpg https://i.imgur.com/0m8XehV.jpg Nothing rare, but my two little USB erupters arrived today. Set them up on a shelf above my desk with a D-Link DUB-H7 7 port hub I got for $23. I quickly realised that they were reaching 70+ deg C temps when I was setting them up and the 2x 15 watt server fans really help (but they are running at 3.3 volts so they are essentially silent). Miners now get better temps of about 45 deg C (25 deg C ambient) after running for a while. Getting <1% hardware errors in bfgminer I might have to look at that later. Is there any components on the other side of the PCB? Or is the aluminium heatsink removing heat through the PCB itself? Some micro-sized heatsinks might be in order for the ASIC chip on the top side in any case...

There were a couple of guys playing around with some clip-on heatsinks that reached the chips pretty nicely.. might be worth looking into. Just did a quick search but couldnt find the post . will look again a little later. |

A bit of a Medusa at the moment, but I'll clean it up later:  61 AM USB hashing away at roughly 23 GH/s  |

Some micro-sized heatsinks might be in order for the ASIC chip on the top side in any case... You realize your fans are easily using 6 times (or more) as much power as the USB miners themselves? Those fans are also noisy as FUCK. You can be fine with just a gentle breeze. The USB miners actually don't need any cooling at all. The manufacturer has tested them with zero airflow and even removed the heatsinks (the chunk of metal with the BTC symbol on it) and they still ran just fine with no increase in HW errors. If you really feel you need to run fans, get something slow and quiet. Something that uses very low power. A 240mm fan that only draws 0.8 amps @ 12v will cool 50 usb miners without a problem. |

There are no components under the heatsink.  Source: The teardown by codinginmysleep, here: http://www.youtube.com/watch?v=GPqPlLFuEX4 |

True for cooling, mine are sitting on a top shelf, no fans or anything... To be honest I am happy I got rid of the noise

I thought for a moment that I will miss the days of my rigs, and that it will be hard to get used to the silence... Boy I was wrong . No noise, no heat, and most important, no need for watching if some of the electrical installations will start to burn. To be clear, that never happend but it was in the back of my mind always |

what did you use to build the rack? I was considering legos, but i like yours. I'd just want to add clearance for my fans. |
