(shortened post size ie was massive) Thanks  I will try it on the forum. Unfortunately I cannot open the S4's case because its under warranty from ebay and I just bought it last week. It's also my mistake because of my noobness buying stuff in ebay. So again if everyone is interested there's a 30 day warranty and the firmware is updated but under factory defaults. Or I will talk to the guys in the said forum is they have one C5 that willing to exchange with a brand new S5. Regards and Thanks, johncban I would highly suggest not trading a S4 for a C1 if that is what you mean. The S5 if you mean the S4 still is worth more in value. As far as ebay there is really not much of a warranty it is more of you can open a claim. At this point I don't know if there are any new S4's being sold that would have a warranty I think it's used market. So it's not really the Bitmain warranty that you want. Thanks for replying again The warranty like is from a bitcoin business the re-sell bitcoin miner machines from bitmain or other independent miners but you mentioned about S5 and I checked it out it seems doable but C1 is a questionable miner though because it needs a liquid cooling system. Regards, johncban |

I picked up a few of those a couple of months ago based on dogie's recommendation. They absolutely will NOT work to properly cool an S4 in average summer temps across the US. If it is only one S4, and heavily underclocked (how are you changing the voltage? just curious) and you have it in a room with the AC then sure, they work. Otherwise those fans are for S3, S5, etc, not S4, they are too weak. Thanks for your reply, I just remove the voltage values like my s4 (under miner configuration > advanced miner configuration) and yes summer is coming here in Jersey City that I decided to put my two S3+ to a small server cabinet; however, deep of my mind I cannot just let go of my S4 but since you mentioned about summer because sometimes Jersey City's summer can reach up to 90 degrees or 100 at worst with humidity involve I just have to tell it via ebay or if someone here at bitcoin talk would be interested. I actually bought the machine for about $560 from ebay but I am willing to sell for about $500 or In exchange with a single S5. I just dont wanted the machine to be wasted or even burn my apartment down in summer  If you guys know someone who are willing to buy an S4 for $500, please let me know. Thanks and Regards, johncban With being new you will have to use escrow if you do sell it. But there is a forum for selling: https://bitcointalk.org/index.php?board=75.0You might give it a shot. Also might check Craigslist to see if you can find anyone in your town without needing shipping. Thanks I will try it on the forum.

Good Evening kingcolex, I would like to know if the fan above works fine to your S4 miner? I bought an S4 last week and unfortunately the noise is unbearable that the land lord noticed it last night because his daughters cannot sleep in the first floor. I am in second floor but the noise is quite concerning. Thanks and Respectfully, johncban |

Good Day All,
I bought an S4 miner and almost got evicted because of the fan noise so I decided to re-sell it back to ebay; however, I am conflicted and badly wanted to mine bitcoin more so I can pay my bills while saving my money for masters program. I am wondering is there a DIY manual to change the S4's fan and what kind of fan type do I have to buy that have low dbm and as silent as S3's fan so that my land lord who lives in the first floor won't complain.
Thanks in advance,
johncban
I guess it depends on what you want. As far as most quiet miner the Avalon 4.1 nothing has came near it on quietness. And I have tested a lot of miners, but yes with this one you pay a premium. - https://bitcointalk.org/index.php?topic=1008726.0 Thanks for replying notlist3d, I would like to ditch the PSU currently I have 2 S3+ and an external PSU seems a head ache because my place didn't have enough space. Plus I need to reduce the configuration time; however, thanks for the info I will keep that in my list to buy if I cannot upgrade the S4 fan. Respectfully, johncban Try downclocking the S4. But I think the S4 is the loudest miners out there. Don't know if downclocking will do anything. I think if he want's to keep the S4's. It will likely be a combination of underclocking and switching fans. But I don't know if that for sure will fix his problem with neighbors. It just is a heck of a miner on power. I would hate to have a landlord who is mad about sound from 2nd floor. I would like to keep the S4, because I wanted to use my BTC revenue for paying the bills as I work to save money for my masters program that I wanted to take next year or after several months. Unfortunately, I thought that S4's dbm would not be a big deal for the two floor apartment Respectfully, Jc |

Good Day all, I purchased my first Bitmain Antminer S3+ from ebay and I use is since 2 weeks ago. It works perfectly, however, this Thursday night Verizon mistakenly cut off my FIOS and the Bitmain began to open its tone error sound indicator. So I close the PSU (850W) then at Friday evening or yesterday, Verizon re-connected my FIOS. Unfortunately, after I connected it properly and waited for 45~50 seconds the red LED powers solidly then after the Ethernet indicator (both green and orange) turned off, the red LED turns off it self then the Ethernet indicator turned on and every after 50 seconds it blinks. I checked my Verizon router admin page and I cannot see the IP address for my Bitmain... I cannot access the my Bitmain page for configuration re-adjustment. I restarted the miner but still no good its the same issue. I really need help or information to tackle this issue and I hope my miner is not broken :( For further details please see attached pic...  |
