hi there.. i had a problem with an antminer s9 and i mailed support. they sent me a firmware for my S9 (that was broken) to try it out and see if it help my surprise was that this firmware has Fan control and i could set the fan to 100% my question is. its safe to install it on my others S9? the customer guy said that this firmware could damage my machine if it was purchase after oct 1.. what u guys think?

u know if "fan 3" is back or front fan?

yeah they are connected in the right place. im still getting 1440/1800 rpm on "fan 3" thats front fan right?

but its weird that front fan was running slow now is the back one that is running slow and the front one is now running at normal speed..

i did it.. but one of the fan is still slow.. its stuck on 1800rpm and wont increase

so its a normal behaviour for a diying fan ?
it goes from 1680 to 3700 rpm.. it was working at like 4500 without droping..

EDIT: after cleaning it it works now.. but now the other one is slower.. wtf

hi im having problem with my antminer S9
one of the fans is running realy low and its making my miner go to temps above 88 grades

heres a pic

this miner been running for like 2 months and no problems

both fans turns on but one is realy slow

well i have a big problem with this shitty company

i bought some s9 in november.. and one of them came with the controller board faulty.. i sent it back for warranty 1 month and a week later it arrived

after it arrived 9 hours later a hash board broke (dont know why i have more s9 working just fine), i contacted then back and sent the hashboard again

now after 2 weeks they reply that i have to send the whole machine back because i purchase it after 1 octuber

now what makes me angry?

the customer support told me to ONLY send the hash board i have this on mail.. i already lost 2 month of work with that antminer increasing the time ill go ROI.. they sent me a 12.93ths antminer and i bought 2 13ths that time.. the other one is hashing at 13.2 and this one that 9 hors that worked was working at 12.3

now my real problem is i dont have anymore money to pay shipment since where im from its realy realy expensive like 200$ i already paid like 300$ in the control board and hashboard.. now with the shole machine it should be like 200 or 250$

can anyone here give advice of what should i do ?

i want to take legal action against them but i just want to fix my damn antminer and keep working..

here is the mail from BARBARA

i tried reconecting the cable already but still not working..
here is what it does when i connect it http://youtu.be/RyfUlgTclVg

(my other S9 is working just perfect after cutting the cables)

btw the miner is shutting off, it just stay ON..

i found a solution cutting the blue cable from the fans, i tried with the front one and it worked when tried with the back one the antminer stoped working.. i hear the fans but no lights turn on and i cant connect to it.. any help plz?

where can i see the firmware version? and what speed and label are u talking about?

yeah they already updated it for S9

yes i have a program named awesomeminer, where i have temps of all miners in one GUI

hi is there a guide to do this?

i just upgrade the firmware, its the lastest batch 13 TH, original fan everythig is brand new.

sorry about double post.. the other one have so many post maybe mine will be unoticiable.

hi i just receive some antminers S9, but i cant edit their fan speed.. the fan speeds are realy slow and im getting high temps, i was getting 50/60 with my s7 now getting over 100 with S9 but its because fan speed.. any fix for this?

why  i cant max fan speed manually in S9 but i can in S7?

hi, i just got my antminers S9 but they are working at temps over 100, but all my S7 are working under 50 temp, i have good cooling, (with s9 i can not edit the fan speed and its realy quiet it might be the problem) is there a way to activate this setting ?

probare clevermining.. la has probado que tal es ?

any advice on that?
i have some things i dont understand
ppl tell me to mine zetacoin, neoscoin, peercoin and not btc

my question is do iget more profit mining something else?

i tried 1 day of peercoin i got 33% less from it

tried neoscoin 2 hours didnt make a cent

im using coinwarz so i know what coin is higher than btc the thing is all those coin take way longer than btc (pps) to farm
can u educate me?

is there something else i should be loking beside that if certain coin is higher in exchange than btc?

what u guys think about clevermining?

if u guys could explain me all this conserns as if im a 5 years old boy i would apreciate it alot!

i got an s7 just to start, planing on get some S9 after i understand everything i should know, (free elec and money to spare)

NOTE: this is not a post about if i should or should not mine, all i want to know how to mine more efficiently

thank you.
