im blown away by the number of people paying these ridiculous numbers for miners that wont ROI in 6 months or less. I saw an article saying the S9 was an amazing investment and they even said if everything stays the same (diff, price, etc) then it will break even in a little over a year.....a year!?!?! how is this a good investment guys?? just wait until halving.....the price will need to drop otherwise they wont sell any miners. if the temp numbers people are throwing out there are true how can you expect these things to even last a whole year?? 70c at under clocked speeds is just too effin hot! running my s7's at a lower fan speed but still at full speed doesn't make my temps go this high....if they have the same issue the s5's and above have with burning themselves up once internet goes down for extended periods of time you all r gonna be screwed.

If you set fans on manual at 75% the internet goes out but the fans run so no burnout.

Buying miners vs buy and hold is a very complex comparison for roi. Depends on many factors.

As for everything staying the same (diff,price,etc) yeah you are correct 8 to 12 months for breakeven.

I have cheap power so I break even on Feb 14th 2017. if units drop 70% in price my 2 batch 1's sell for 1300 and I make a 1300 profit I also get free heat from

OCT 1 to FEB 14 about 9000 btus 24/7 So I see quite a few reasons take my chances with with them.

i had the howler issue as well from the fan. it seems to be a front fan from an s7 with a longer pigtail attached to it. So i took the rear fan off an s7 and used that on the front and all is quite now in the house.

the fan speeds aren't the same for both fans. one is supposed to spin faster than the other if im not mistaken so swapping the fans will mess up the miners ability to push/pull the air out of it.

front fan was running at 4400 rpm at 100%. swapped in the rear fan from an s7 which normally running 46-4800 on an s7. So running at 4400 is no problem. fan is running and stays at 4400.

now if you were trying to use a front fan on the rear which normally spins faster then yes there may be a problem but rear to front is ok

So, I'm running an S9 inside my home (yes, I'm crazy). With the default settings, the fan was unbearably loud. It was just unmanageable. I tried the vent filter trick, and while it cut down the train whistle sound, it also caused a deep echo effect sound to come out, actually increasing the miner's overall volume substantially. I had to take it off.

So, I took advantage of the "max fan speed" setting in the config, and I set it to 40%. At that speed, the fan noise can't be heard through a closed door. Obviously, that's not enough to cool the miner running at full tilt, so I also downclocked the miner to 475 and let it run for an hour or two, then gradually increased the clock rating to ensure it doesn't overheat. Currently I'm clocked at 550MHz, and the temps are about 70-ish for the board and 100-ish for the chips. At present it's hashing at about 11.8 GH/s. I can probably clock it up another 25MHz or so before it starts throttling.

Just wanted to throw this out there in case there are other home miners interested in running the S9!

When they realized that their miners weren't hitting 14TH reliable they probably did a bit of testing, and Batch 3 are Batch 1 miners binned for lower speeds.

Kind of weird strategy from Bitmain to ship Batch 3 before Batch 2..
Can't really enjoy it as Batch 2 -buyer..

Not really, Batch 2 buyers paid less than Batch 3. More than likely they finished production early and are offering to ship immediately for an extra $100 or you save $100 and they begin shipping on June 20th how the original listings terms stated.

Yes, it could just be all about money.
So it basically could be the same production batch, but those who are willing to pay more are on the VIP list a.k.a. Batch 3 .

My s9 seems to run hot. Pcb 68-72 and chips 98-102.

What are others seeing for normal temps for batch 1s.

Being able to see the individual blades' performance opens up the possibility of combining good or bad performing blades into a single unit and then clocking the unit appropriately for the blades (presumably voiding the warranty in the process though).

@yxt have you tried downclocking at all to see what happens to the blades that are not performing as well?

Also out of curiosity, has anyone from batch 2 or 3 received a shipping notification? I am curious if batch 3 really is going to ship before batch 2.

Got notice last night from Bitmain that my b3 has shipped. Literally about 7hrs after they confirmed payment. Shocked

Got my batch 3 tracking number this morning, indeed I will be receiving my batch 3 on the 20th when the batch 2's start shipping. IMO totally worth the extra $100, time will tell.

why you guys worry about dust on the machines? I've got dust on my machines and simply take out the fans, use brush and vacuum the dust that block the heat sink and put it back both fan once a month/two

I only use the air compressor and a vacuum cleaner.

see below...
the other 2 units are over 13.3 but no unit reach the advertised 14TH/s

(picture above)

You are right out of curiosity what PSU's are you using? Also have you tried another pool just to see what it does? (Pool should not make a difference as Kano works but just being through)

Just wondering on those things as that would be heck of a bad luck to get so many under.
