What would be a good fan replacement for the S2 that would reduce the sound significantly? The S2 has been great, but the noise is quite loud.

Yes. Before the update I had to edit cgminer.sh after every reboot, now I don't have to.

the new firmware fixed the subnet issue for me   

Its pretty bad that the cards are not held in by anything and the slots are very loose fitting  I was lucky, after getting my cards reseated everything booted up. Its been running for almost 6 hours now and getting around 1% rejected. Will see if it will run throughout the night.

Also.. those vinyl straps on the box are an invitation for the ups guy to one arm huck the thing.

Yeah, mine worked after I reseated the cpu board.

thanks! editing that script did it for me... it seems to overwrite it on every reboot though    i'll have to look for where thats happening.

can't ssh in either.  the administration screen has no entry for cgminer version.

How do you get it to start mining? I had to make sure all the cards were plugged in and then it would boot. But now I've set up the network, can access the administration page, and entered in all my information, but it doesn't want to start?
