anyone know of a quieter fan This S4 is freaking loud!!!!!

The reason it's loud is you need a fan to go up to just shy of 5,000 RPM's to keep it cool at default clock speeds in warm temperatures during the summer.  If you under clock it, it will make it quieter because of less heat to contend with, which means less fan speed.  Unless you have it working in warm climate.  If you have several of them, you are better off putting them inside of something while keeping them cool to keep the noise down.  Don't forget to get the heat out of the closure.  That's the most important thing!

Don't try to run this rig at default clock speed of 2000 GH/s with fans that are lower RPM.  Otherwise, it will run hot quite easily and possibly shut off periodically for reaching the 80 C threshold temperature depending on the ambient temperature they are sitting in.  

That is my opinion.  This rig just runs much hotter than the S3's.

So, basically, the only way to have these quieter is to run them at lower clock speeds in a room that does not have to high of an ambient temperature.

I just got a used antminer S4 in from gawminers and had a similar issue it was failing to boot, when i started it the fans would run full steam and the LCD would light up but show blank. After waiting on hold with gawminers and not getting through i opened it up. Checked all connections everything was fine. I popped the microSD out reinserted it, hooked everything backup and lo and behold she fired up this time. So if your having a issue like i was and that other fellow had for some reason popping the SD out and reinserting it does the trick. Makes no sense but it worked and now i am hashing along just fine. Maybe bad SD terminal connection and by sliding it out and back in cleaned the contacts? The contacts are silver or similar I think they should be gold. maybe some kind of corrosion developed between the sd card strips and the terminals? Thats the only logic i can guess at.

Sorry you had to deal with the RMA process but glad to hear your miner is hashing again!!   Cheesy


Now this i call good support,i got my replacement fan today, it was sent on 13 feb. Thanks BITMAIN for the fast response and fast shipping!!! My miner is happy again Cheesy

It may be easier to return the whole unit to Denver, Colorado.  Or you can try 1 last thing to try hash with 1 hashing PCB with the PSU, if it works, power it off and add 2nd, and so on. If the PSU is defective or not sending enough power.

But usually, if good beagle bone and a good microSd won't work, then it would be the S4 control PCB to be the cause.

Please email [email protected] to request a replacement with your Bitmaintech.com Order ID and attach a Order Confirmation Page with the tracking number.  Your tracking number and the order number combo is used for the internal RMA # for identification

Thank you

we are sorry to hear that, it may be a time for the Control PCB unit to be replaced.  Could be the control PCB itself or it could be the beagle bone or combination of both.

However, once in a very while...  the MicroSD card physically goes bad.  We have seen a few cases where simple MicroSD card replacement from a local store (kingstone or Sony 4GH) took care of the problem.

if another MicroSD card doesn't work, please proceed with the parts replacement via warranty.  support @ bitmain . zendesk . com

Thank you

Using windows, is there software to flash the S4 image? I cant seem to find any software. I looked at windows disk imager but it only takes .img files

I tried this, it still did not work. I cant connect to it at all, but both LED are Green and the LCD screen is lit up just blank

Hello,

I have tried switching out the sd card as well as the beagle bone black. Neither has worked.

So this is what I have going on with the Antminer S4. When I power it up it turns on and the fans start turning on full speed and the LED screen lights up. However nothing is displayed on the screen and the two small LED lights to the side never light up. It runs like this until I cut it off....... As a side note I have two antminer S4's only one is doing this, the other works fine. If I switch the SD card from one miner to the other the one that is working continues to work and the one that is not working will not work no matter which SD card is in it. PLEAS HELP......after posting this and reading it the thought accord to me that what I should do is just flash the new OS to my SD card with the miner that is working. Sure enough it works Cheesy Sometimes it dose a lot of good to right your problems down. Hopefully if any one else is experiencing this problem this post will help them.

I wish it was that easy. I tried what you did but it didnot work

hey, one of my miners has problem that the lcd is lit but the letters are not so black, but everything is working ok. Have you tried scanning your network with ip scanner to see if only your screen does not work?
You can try angry ip scanner, search it on google

I would say this is prone to happening, and with the S2 Ive replaced the SD card twice. Other RPI/BBB-controlled ASICs (BTCgarden, rockminer, bitfury) all have the same problem - SD cards dont always handle reboots or power 'blips' well.

I had to get replacement fans for an S4.  Two of them failed on me.  The propellor with axel came out of it's socket on both of them [exposing the copper coils].

I decided to order some fans to have ready to replace failed fans in the future to avoid too much down time.  I also bought extension cables, as the cables that come with the fans are not up to 27 inches long [Needed for the furtherest fan in the back left of the unit].  I purchased three (3) Delta Electronics PFC1212DE 120x120x38mm Cooling Fan, 252.85 CFM, 5500 RPM, 66.5 dBA, 4.8 Amp, PWM Connector.  This fan comes fabricated from the manufacturer with a 4 pin connector.  Here is a picture of the fan:




The following is a video review of the fan to also show watts consumed at full speed:  approximately 51.2 watts at full speed (5500 RPM & 252.85 CFM).

It seems there's a problem with the extranonce.subscribe implementation in the latest S4 firmware.  I was able to get it working with westhash by putting #xnsub at the end of the URL.  However, when the price dropped below my parms to make it worth mining, the pool didn't switch to dead.  Furthermore, the speed (5s) changed to 0.  All rebooting the unit did was change the speed (avg) to 0 as well.  Lastly, it happened to both of my S4s simultaneously.  Only once I removed the #xnsub from the URLs did both start behaving normally again.

For S4, if the miner powers up, the back light of the small LCD comes on but screen shows blank, highly likely it is the MicroSD card either got loose inside, or data on the microSD card got corrupted.

You will find the MicroSD card inside the case, behind the LCD panel and next to the PSU.  There is a Black Colored Beagle Bone Black and there is a little MicroSD card slot on it.  Lightly push the card and it will pop right out and push it back in.

Then please try to power it back on and see if it boots up.  If not, you may have to use this software to reimage (Write) the factory default data of S4.

yes 61...  a bit too high but every customer have different deployment method.  Looking at the running up time, at least the high end is stable or managed some how, so it's not crushing the unit.


For some reason my chain#1 on my units are the hottest not chain #4.

because chain1 is connected to J7 and fpga cannnot set your proper voltage value to J7 connected hashboard. chain1 is always working 0750V. i told a lot but no ones listen...

Hi cypher
as i can see you say that chain1 is connected to J7 and in previous posts i saw that chain1 is the top hashing board, but in my case J7 is connected to the bottom hashing board and that is chain#3 right? and what did you meant when you said connect to the neighbor board? is that to top the botom? please clarify Smiley
Thanks in advance

no, doesnt matter which hashboards is top-bottom or right-left. J connectors are define which hashboard is chainX.
you can easily change ones to another... if you can move j7 connectecor to top hashboard, you will see 0750 V (you cant set your own value to J7)

on fpga board :
J7 means Chain1
J9 Chain2
J2 Chain3
J6 Chain4


Thanks that explains alot. So can i take off the cable from J7 and connect to one of the free slots on the top hashing board? Will that work?

Use FPGA board J connecectors for change, dont use hashboard connectors.
