Hmm, mufflers. That sound like a great idea, but pretty expensive.
I guess for a S7, its such a big unit that you can soak it, however.

But i'm wondering if i could not DIY one. I'm guessing its just the foam used in sound absorbent panels rolled in a tube of aluminium.

I would have to see how its made but i'm pretty sure with some cheap aluminium sheet that i already have at home, buying the sound absorbent material, i could handcraft one. (With a healthy dose of duct tape)
Edit: Looking at pictures of it from other angles this would be very easy to make. Its just rolled foam.

But i'm guessing you might want one at intake and exhaust?

I purchased diy  and pre made.  that link is premade

diy for intake  is this

if these do the job they will be worth the money.

Please let me know. Those foam look low quality/density, not sure, but i think i would buy a big roll and make noise absorbent panels too if its dense enough.

157 Sept 4 2015 ---- This was partial  but it is +13  on a norm of 144  that is over 9%    that is really high number we  need to see the next few days.
150 Sept 5 2015 ---- +6   for the day about +19 for the first 261 blocks
142 Sept 6 2015 ----  -2        +17
151 Sept 7 2015 ----  +7       +24
138 Sept 8 2015 ----   -6       +18  It did slow a bit.
144 Sept 9 2015 ----   0         +18
168 Sept 10 2015 ---  +24       +42                brutal number but 3 in a row is what we need to worry about so lets wait until tonight to see
163 Sept 11 2015 ---  +19      +61                back to back high numbers
144 Sept 12 2015 ---   0         +61        and normal  which is good   maybe it was variance  stay tuned
144 Sept 13 2015  ---- 0         +61       and normal again which makes the 10, 11 sept days a little less scary
151 Sept 14 2015 -----+7        +68

we will be over 150 today so +75 or +80

this will be a good sized jump

This week is going to hurt:

Bitcoin Difficulty:    56,957,648,455
Estimated Next Difficulty:    60,226,440,016 (+5.74%)
Adjust time:    After 176 Blocks, About 1.1 days
Hashrate(?):    454,976,728 GH/s


Just have to wonder how long can we keep getting 5 percent or so.   I don't see a end in sight for the moment.

[Mikestang]

I think we're going to keep seeing 5%+ as all the new gen hardware comes online and the northern hemisphere cools down for fall.  The network may keep growing like this all the way to the halving.

I think we were all just so "shell shocked" by the difficulty increases during 2013 and 2014, a small increase of 1% we just shrug off. In any other industry, 1% growth every 2-weeks would be considered crazy. I agree the days of 1% are over for at least a few months. It might not be quite as a bad though if Bitmain is doing most of the increases. All of the other obvious names (e.g. KNC, Bitfury, Spondoolies, etc), are all pretty opaque these days.

I think so which really is sad.  Roi at today's prices is hard at 5+.... just is going to be tough to mine.    Will come down to cheap electricity only.

And just think were still approaching having each period were one closer.  Scary future looking at it.

At 2% & 0.05$/kWh you won't even be able to ROI the S7 before the halving according to BitCoinwisom calc with 2000$ as total cost. 5% Indeed sound scary, but i don't think 5% can be sustained indefinitely.

I am pretty sure in a few months we'll reach the new balance with the new hardware where the Difficulty will be more stable. Still, not sure the S7 is ROI-able either way before the halving.

Seem even more gloomy for less efficient hardware.

Not indefinably but it can for a while.  Just think bitmain has their own farms that they will upgrade spots that used S5's sold were.  Then there is hashnest they are going to make a decent amount for the hashnest users.   And then there is batch one buyers.  That right there is a lot of miners.

And that does not include any other companies in the mix.

we are pushing 160 for today.   So we will be about 100 blocks over pace.

7% looks pretty much possible for this jump.

Ouch.... 7 is going to hurt.  I think someone is pumping out the miners at a pretty amazing rate.   This scares me.

The thought of 1 or even 2 companies being able to produce so much hash in one period is scary anymore.

[alh]

I wonder how much of this is "latent hashrate" that was off for the summer due to cooling costs, or perhaps higher electricity prices during the summer months. Also we are all assuming that Bitmain was putting in S7 hardware and selling off 100's of S5 miners. Those S5's were bought and are now being run by somebody. I think there is quite a lag (i.e. many months) for displaced gear to actually disappear from the network. How much BFL gear is still hashing? Original KNC hardware? At some point they become a sunk cost and they get run until they are seriously in the red in terms of electrical costs. As Phil has said, a lowered BTC price accelerates that process.

I don't know for all but for me in the midwest it's same power year around on cost.  It seems to vary be area on this.   We have cooled down some but it's still not near winter weather where I am yet.  I think winter miners are still to come on turning on.  Which is sad to think about.

As far as old gear I think look at A1's and S2's.  I think there are MASSIVE amounts of these in cheap electricity places still making money.  Eventually they will go offline but so far it does not seem like it. 

BFL really did not have much big gear they had trouble with little gear for the longest time.  I don't think there are a ton of that big rig or what ever they called it, but those most likely are offline.

With less than 17 hours to go, bitcoinwisdom and nextdiffculty are both converging on 4.3%.

Doesn't seem like we're going to 7% this time (I hope!)

Any my high 5 percentage was looking so good for so long, looks like we'll have a sub-5% diff change this go which is much less that we all thought at points during this adjustment period.

[notlist3d]

Looks like we are going to do better then I expected with  under 5.   Kinda sad when under 5 feels like a win at some point.

I really want to see if this continues onto the next week.
