A bit of a Medusa at the moment, but I'll clean it up later:

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...

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.

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 Cheesy. 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.

K'nex... I've been building with them since I was 8 Smiley.  Much better for structures than legos.

You're really going to argue using a 8 inch model of an X wing?

For anything with motion, K'nex wins.  For anything structural, K'nex wins.  I'll give the detailed modeling to Lego, but it is only because they make custom parts for each model.

Besides, if you want to show Lego is bigger and better you need something like this:


Edit: Oh shit, those are people.  I withdraw my first sentence, but once again custom parts for each model Tongue.
