+1 to all the Blade Runners that re-used their packaging foam as mounting. Well played, sirs, well played. Those fans they shipped don't cut it. I'm using two case fans side-by-side across the heatsink and we're all good. Tried Bitminter and failed horribly (12% efficient). Used Slush with a separate stratum proxy and I'm at 96%.

Wow that failed, sorry. Also one of the fans provided is leaking fluid and now growling away. What is this tiny 2 pin connector called, might get some more.
You can cut the connector off the cheapo fan and splice the red and black wires to a case fan. Works much better and two cover the whole heat sink.

I have 2x120mm on the fat at the back and its still very hot to the touch. I kind of feel like its way more than 80W of heat should be. I'll take the power meter from my comp to this when I next turn of. The 2x120mm one is actually way hotter than my 1x120mm one.

I'm using these http://www.avadirect.com/product_print.asp?PRID=17206No extra heat on the wires. .38 amp on the thermaltake versus .12 amp on the cheapos. It shouldn't be running hot.

I'd sooner wire the case fan to the 12v power source you're powering the asic with. No point drawing more power from a board than necessary if you can just use an external PSU.

Yeah can't work out why this one board is running so hot.

I have 1x 200 mm fan suspended from a rack, and the blade suspended infront of it. Churning away at 10.7 gh/s, blade is cool to the touch.

If it restarts again I'll probably give mr cat a message as I don't feel comfortable at these temps. Its giving off the 'really hot graphics card' smell and the heatsink isn't holdable. Not much more I can do to add cooling other than add some tiny vents, but we're talking +10% cooling power which isn't what this blade is asking for.

For the owners with overheating problems. Don't concentrate your fans directly on the heatsink of each blade. Try to create an "air channel" placing fans in push and pull configuration. in my experience it's a lot better.
It's easy to mount the blades vertically using the method shown by lightbox.
I'm cooling 4 blades with 1x180mm fan and 2x120mm, without heat problems. It's important to have the hot air removed from the room as well.

My blade started rebooting this day about every two hours. The power board is about 70C. Set clock to low to see what happens. Should not be a pool problem. I have a fallback pool and every time I notice the blade has rebooted the pool is switched too. Seems the blade stops hashing, then switches pool, then rebootes, then hashes normally for some time.

Yes. Don't blow air onto the heat sink, draw air through the fins and out through the fan. The fan should be positioned directly next to the sink and you should feel slightly warm air on your hand.

Happy to reply my miner is working as intended, but I can't get stratum up right now. It's REALLY picky with pools with getwork, but mining at nameparking to get nmc, ixcoin, devcoin on top of it and it's working really well there, my backup is btcguild and it works well there too. averages about 12 ghs a second

Wow hang on, its NOT the hot one which is resetting! The hot one is hot but happily churning away with 100% uptime - I'll try and get it cooler by going push pull though.
The one which is resetting was only ever warm to the touch and has one fan on it. I can't see it being heat related resetting, nor power. It can hash for 12+ on low clocks, but resets after 4 on high. What other things can I look for?

I have migrated my asic miner from its wine box into an old G5 case taking the airflow notes into account. It remains pretty cool and has 99.38% efficiency (13GH) at slush's pool using stratum proxy. Still using the original foam as surface materials. Not gonna touch it any more yet so far. This time I did succeed in reducing electrocution and fire risk.
Great work form the Asicminer team. I hope everybody got theirs up and running.

Very happy with mine, this is one of them.. Total MHS: 12988 Received: 0000448881 Accepted: 0000444397 Per Minute:177.47 Efficiency: 099.00% Up Time: 1d,17h,43m,58s Local stratum proxy certainly seems the way to go, I tried direct getwork to some pools and efficiency dropped down into the 70s, and something like 9/10GH was actually being achieved. I'm hoping for payback by October or so, taking difficulty into account ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

I wonder what backup pools would you guys recommend?
Currently, I'm using slush which I found reliable from my gpu mining days and still very happy with it.
As far as I understand the miners would automatically switch to the secondary pool if the primary goes down. Is that correct?

This is wierd. My blade stops hashing exactly after 57 min 30 sec then swithces pool (with no hashing) then reboots. It happened 5 times in a row now. exactly 57 min 30 sec. Is it firmware bug?

Is it firmware bug? if there is a bag, it will be affecting everyone. Problem cab be in insufficient cooling. Once, I sorted out cooling, my blades can run days with clock on HIGH overclocked with voltage 1.24 I have no back up pool and mining on btcguild, no restarts at all.
