Look at those temps, 80+. That is your problem, your room is way too hot.

Thanks for the info...

But I've got 5 other miner running anywhere from 75 to 100 degrees and everywhere in between...

Different people have told me different things on the temperature.. but I know at least one said they run up to 105...

I am in a completely controlled air cooled environment that stays at 70 degrees year round (underground cave)..

I have fans blowing to move air as well...

Changed both fans from another working unit and still doing the same thing...sometimes shows both fans, sometime one fan and rpms from fans are allover the place..

Very strange...Any other ideas?

I think we all need to look at all the reasons to mine. Most are mining to make money. We should also mine to support the network and keep it healthy. The large mining pools provide a somewhat consistent payout but take a bigger piece of the pie than t he smaller pools like Kano. The large pools do not help keep the hashing power distributed and the network secure. We need miners distributed across the network more evenly to support the network. This Bitcoin world is managed by miner decisions and with the recent influx we have a whole lot of people who do not understand that. My hope is that the mining world would smarten up a bit and that we do not self destruct.

Any miner that wants to continue mining into the future should be mining on a pool that has less than 10% of the network hash. At least it would be a good start.

Mine on.

This. More of this, is exactly what OUR COMMUNITY needs!!! A little bit of "promoting" could seriously go a long way.
There are many like minded individuals out there, we just need to get "pooled" together!!!

Well, I give up... The Android App doesn't send me a new Block notice, the other web based tool doesn't send me a new block notice.  Seems nothing does.   So I just decided to fix it myself.

I created a little perl script that reads the pool API and when a block change happens it will send me a pushover notification!... Problem solved.

I don't know how fast is *too fast* to ping the API, so I've slowed that way down for now. (2 mins would be min notification time).  I use Pushover for a bunch of other things and it's easy enough to use so TADA

I did make the little pushover app subscribable.  I want to run it for a block or 2 (my incentive to make them happen quickly), just make sure it works ok.  If so, and there are others interested, let me know and I can provide the Pushover subscribe link.

yeah, maybe now I'll get a notification of a new block found!

yes these are all from the same S9 machine

trying different things... fans are all over the place..speeds up and down...sometimes only 1 fan shows up at all...

switched out fans, put in new control board...Updated to Nov 2017 firmware.  Would any other version of firmware take care of something like this?   It is a 13.5 s9 Antminer.   It is at least running now and hashing...

before it would run 10 minutes and quit hashing... but the fans were revving up and down every 15 seconds...

It is running now, still revving up and down, but for now I can live with it till I get some more new ideas...

I bought this one off ebay and of course they showed the hashing on a piece of paper, but probably after only after a few minutes...

I suspect it has had this problem all along...  

I got suckered again I guess...

Any other ideas or thoughts would be apprecated...

Thanks to all!

The fans are SUPPOSED to cool the hashboards... its working exactly how its supposed to ?

The fan revs up speed because boards are TOO HOT.... as mentioned

[Jeremiah1610]

You need air temp to be 65 or cooler, really 60 if you want to keep them under 6k rpm. Your machines are fine, it is your environment that is the problem.

[A.Delaney]

Yes but why would the fan show it’s running 30k rpm if everything’s is fine? My S9’s ramp up and down. One between 5-6k and the other between 4-5k. Temps are mid 70’s. I don’t think that fan can even spin that high. It has to be a false reading and that would explain why it stops hashing.

Peck. What psu are you using? Have you tried a different one?

[kano]

Kano, now that you're awake, can you also add a to-do for higher precision percentages amongst the website pages?

Four decimal places would be great since I notice some places it gets rounded to three or even two decimal places.

Thanks, and great work on everything else!

Oh - awake again
Well I guess so.
Anyway, I've put it on the todo list to look into it.

[kano]

I think he's just going on the .9% fee, as that is all that kano makes besides his own miners. 

And I have heard directly from Kano that he does not run his miners unless he needs his house warmed up.  All of my discussions with him demonstrates that his primary mission for this site is the heath and future of bitcoin.  And yes, he probably does all right with the fees too - although having close to a dozen servers around the world is also not free.

Heh - there's a lot more than a dozen

This month I've been spending a lot of BTC on getting the hash rate up ... it's working ... and I'm losing lotsa BTC

I've come up with another idea about throwing more BTC at getting the hash rate up - targeted directly at large miners - since we need a number of miners in the 5-10+ PHs range.
Once the accounting is done and verified all OK, I'll sort that idea out.

Of course all this BTC I'm 'throwing away' is BTC I've got from the pool fee, so no better use I can think of it!
... other than paying for servers and so I can survive ... and anime

What do you guys think of the antminer r4? Thinking about buying two from usa (im uk) and running them on kano pool

Is it worth the investment?
I know s9 will have a better watt/th ratio but these will be run at home were i have to pay electric
My other miners i run at work were i dont pay
Also do u guys know any reputable company's that stock the r4 and ship uk?
My biggest problem is the import tax

depends on your circuit breaker config at home. 
1x S9 draws 12A at 110V or 6.2A at 220V which gives you 13.5TH

1x R4 draws 7.7A at 110V or 3.9A at 220V which gives you 8TH

S9 is the most efficient miner ... so if you have the amperage availability - S9 is the choice. (noise & consumption aside).  Especially since S9 prices have stabilized recently.

If you have power outlet limitations from a current perspective, then R4 is feasible.  Just note you are sacrificing efficiency & cost, for convenience of fitting in with your home breaker config.

I too built minergain.com for this exact purpose - plus a whole lot more (including tax prep needs and eventually wallet valuation) since I mine on multiple pools.  I am checking with the kano home page every minute and when it changes and the immediate notification is set, it sends right away.  I am thinking I will change it a little bit so that I can also get the payment amount on the email as well - but it may delay the notification by another 10 to 30 seconds.  Not sure what kind fo information people would like to see on the notification email / text.

I have no problems with the android app. Running fine on s7 edge.

Same here. Notifications are not instant but within a couple of minutes.

I would stay away from the R4. I have two of them and both lost 1 board. One after a few hours and one after 6 months. If you read the R4 thread, https://asktom.cf/index.php?topic=1597639.0 its full of similar stories.

Unless you just want a space heater, or they are super cheap, I would buy something else.

[sruyle]

I have free internet where I live. I have never bothered having my own service hooked up because of that. It has worked perfectly for netflix and such. However, with mining, I see that my miners are bouncing back and forth between this pool and my backup alot. and I am running 4% stales. That is alot of hash thrown away.  I guess I need to get a connection of my own after all.

I like it kano, would love to have double the hash rate.
