Checking my farm, I have four 13.5th and two 11.0th s9 autotunes.
All the rest are 11.85th or 12.93th.

Had the same problem with s7's.
My solution was to get some cheap fans the same dimensions as the fan only that were about 1/2 inch thick.
I gutted them and got longer screws to allow for a half inch gap between the fan and the miner, like a little tunnel.
Seemed to get the job done.
I have since removed them since they were at the datacenter and I did not care about noise. At home they were great.
Makes them a bit longer.
I think you only need to do the front OR the back fan. May need an extension on the fan wire.

Hello people!

I recently cleaned up an Antminer S9 after several months of use. The good part is the temperature went down about 10° Celsius. The bad part is the fans are now doing an annoying whistling sound they didn´t do since it was new.  Huh

I have tried setting the fans from 60% to 95% and curiously the whistle is louder at lower fan speeds.

I remember in this tread somebody mentioned covering part of the front fan grille could reduce the whistling. I tried that and the whistle is reduced, but the board and chip temperatures rises. I also worry that's not a good solution long-term.

Could anybody share some advice about how to reduce the fan whistle without the temperatures going up?

Thanks a lot!

there is no way to do it. the grill or at the very least part of the grill has to be covered which restricts airflow which makes the temps rise. if you remove the grill the whistle will still be there too usually. your best bet is to cut a small piece of scotch tape and move it around on the grill until you find the right spot. then you cut the tape as small as possible until you use the least amount of tape to block the airflow which will reduce the impact it will have on the temps. i dont think its the grill or fan creating the noise though. the issue is the heat sinks not being on straight all the time and it makes some whistle louder than others.

someone sold a crapload of btc at 4am est at $903 according to bitcoinwisdom.com
Just a downward spike for a moment.
Was a precursor.
Great part about that is they can only do that once:). It was bound to correct soon anyway.  Was up up and away awefully fast

Exactly. Not like gold ETF's , they can sell paper gold all day.

actually, they CAN using margin and/or futures.
bitfinex has 10X and 20x leverage on some bitcoin positions
I get it that there is some difference, but it would be reduced even further when COIN ETF starts trading.

'The right to privacy matters'
has anyone heard anything of bitcoinworld.biz ?

Please elaborate.


I visited this site today but not able to get it is profitable or not or just a scam site

I would stay with Bitmain or Avalon for your hardware if you are wanting to go that route.  If you are looking into cloud mining, I would go with Bitmain(Hashnest or contract) or Genisis Mining although not as profitable.  

One other consideration is Altcoin Mining and there you can build your own Rig with GPUs or buy an already built Rig from MintMining.com (this is me) or Panda Miner.

Just some advice and options.

This advice is pretty good.

I own Avalon direct from them
I own s9 and r4 from bitmain
I own some cloud hash from hashnest
I have a pandaminer
I have 40 gpus in diy rigs I built myself.

I own a little bit of gear from side-hack.

I don't have a gpu rig from airesIV10

Pretty much every cloudmining site is a scam, but this is pretty off topic for this thread.

Yes - Orange and Green lights at the RJ connection are blinking. But the Red fault status light and Green normal status light do not flash at all, except when power is connected. Also, the small red lights on hash boards do not illuminate.

Visual inspection of the controller looked normal. No signs of damage or anything unusual.
You can telnet/putty into the miner user/password - root/admin if you have the ip address.
I use "advanced IP scanner" to find the ip address.
Usually ipreporter.exe(bitmain app) will work when you press the ip button on the miner until it beeps.
Need the ip address to ping as well.
If the miner cannot get to the internet it won't mine/hash, all bets are off.

The networking piece is working if the orange/green are flashing.
Means it can get to the router, but won't tell you about internet connectivity.
