Thanks for the tips on the noise.

I realize it's the Chinese new year but if you go to their site you can put an order in for batch 10 and pay for it,  you cannot do this with 8.

Also you don't think the comment about batch 8 being the "last stable batch"  means anything?   You could see why that would make someone nervous buying it as it implies that batch 10 isn't stable.

So I'm new to mining and I've really been enjoying getting into bitcoins and whatnot.   Purchased my first s7 a couple weeks ago and have 2 more in the mail.

I went purchase another 5 today (I can run 8 with much electrical modifications in the basement) and the website has changed.

Batch 9 has been removed,  batch 8 is still for sale but unavailable (can't put it into cart and wire the money).   Batch 10 was added to the website about $150 cheaper than the batch 8.

The product description for the 8 says it's the last stable build,  this along with the lower price of 10 leads me to believe that 10 is inferior somehow.  Was does "stable"  mean in this context?    Should I possibly look to buy 5 more from eBay or Amazon (or another source)?

Two final questions,  I ordered 2 noctua fans to try and reduce noise levels,  anyone else have success doing this?

And finally I've been using slushes pool.   Do people generally favor other pools or are they all similar?

Thanks!
