Topic: KanoPool kano.is lowest 0.9% fee 🐈 since 2014 - Worldwide - 2432 blocks - page 456. (Read 5352229 times)

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.

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

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!

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!

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!!!

These images posted are not all of the same S9 are they?

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?

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

Thanks guys for the advise... At this point I am willing to anything... 

Updating firmware now...

Will try to swap a fan from another unit...

Are the input and exhaust fans different if I order some from ebay?  How do you tell?  Are they different part numbers?

Already had changed the controller board..

Thanks... will let you know shortly

The fan is going from 0 to 30k? The reving  up and down is normal for some batches. I have two Jan batches that do it. However they go from 5 to 6k normally. Maybe the fan is bad and it’s not reading the rpm right.

This is hardly advice, but if it were mine, I would first update the firmware ---> swap fans ---> then change controller. What does your worker graph look like? Are you dropping any hash at all or is it isolated to the fan? That 30K rpm reading is obviously an error in which I personally would try those steps in that order. I'm still trying to figure these things out myself, though I've had success in swapping fans with funky readings.

Ok so I got a new controller board for S9 and installed it on the machine...

The old controller board would hash for about 15 minutes and then quit hashing..It was the same S9 with the fan racing up and down about every 10 to 15 seconds.  SO I unplugged it until the new controller board go there.

As I mentioned none of my other S9 miners do anything like this...

So with the new controller board it is mining but the fans are still revvingn up and down every 10 to 15 seconds.  And I mean a lot...very noticeable and noisy.

see the fan speeds below... all over the place... see the image (if it shows up) I hope.

Also what s9 parts would you recommend having on hand at all times (extra controller boards and fans)??

Any help would be appreciated and Thank You!  These miners are frustrating at times...

Would it help to update new firmware.  Is the front (exhaust fan) always the white connector on the farthest outside of the miner?

I would REALLY like to know how that works.

From what I see, the way this pool is constructed, the operator does make ANYTHING unless the pool hits a block - and ONLY then. Please demonstrate if it is otherwise.


MINE ON!

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.

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

What you just said doesn't make any sense unless I misunderstand.  Kano doesn't make anything on our hashrate...he only makes BTC when we hit a block and then it's the 0.9% pool fee.

What he said.   MINE ON WITH KANO-SAN!   Heard some rumors that a big boy or two will be moving back here in the next few weeks.

So far we're thrashing our hashrate on kano.is >> Kano is making BTC from our hashrate and we are waiting for blocks to crack 

Hitting blocks is a necessity, but not to be viewed as the sole component governing a successful mining operation.  BTC price, difficulty, power costs, and even the international political climate are all significant components to the bottom line.  Some of these are predictable - even "calculatable" - until they're not.

Currently 12 blocks in the next 30 days would put us over 100% luck as we should come in around 10.5 blocks in that time frame. Obviously the # of blocks expected changes as the hash rate changes so the numbers here are irrelevant as soon as I type them. With that said, we will get what we get. 12 to 15 blocks would not surprise me nor would 8.

There will be variance no matter where you mine. We have no control over that and guessing is just that, guessing.

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.
