ok got it Aoran's thank's anyway i know what mining is it's not about getting huge money, i am just gonna start a website and learn everything first then i will go for the big one's first .

It's not always about the money , need to experiment on a few miner's and learn and get it done first.

The money will come if you choose the right path and learn and do mining effieciently with small miner's first and then go for the large one's.

Make up your mind...

Mining BTC is for noobs but mining altcoin is risky because pools are subjects to attack ?

I don't follow...

I have found a better mining solution man , will probably buy and Antminer s5 Antminer S9 later , for now i don't wanna setup all those equipment's and stuff , maybe later in 6 month's, when i am able to cover the current costs , with my investments.

Here's a link check the last post , it's ideal for startup websites and startup miner's.

No. These are so old and outdated you need free power to make a profit.

So bit of a weird story.

I got an Antminer S5, factory reset it, connected it to a gold 605W PSU and pool and was mining at 350 hz, 1150 GHz and everything was working for around 12 hours at 60 degrees. Before I shut it down I changed the hz to 150 to see if it quieted the fan and shut it down.

I bought a new fan, removed the stock fan and tried to connect the 120mm new fan. The 4 pic connector was slightly different on the back and it wouldn’t fit the plug. I put the stock fan back on and powered up the machine.

Since then the only lights on the miner are 3 green and 1 red on the control board. There are no lights on the blades and I can’t connect to the IP anymore. The 2 lights in the Ethernet cable are on but not the green or red lights on the right of the Ethernet.

I have tried everything to connect, it won’t factory reset and nothing I do changes the power up sequence. The fan turns on and there are just the 1 red light and 3 green lights in a row on the control board. The Ethernet cable is connected and it works on other computers. I can see everything connected to my router but the antminer has disappeared. It seems like it is not powering up at all.

Please help.

you probabbly touched to much the bbb board and killed it, check your your psu, try reset and put original fan,,,

By the way - the address lines tie directly into the temp sensors (LM75 I believe) so the controller can tell which board has which temperature. PLUG tells the controller a board is attached, but I forget if it pulls high or pulls low. Been a couple years since I needed to know that, but I've got notes on it at the shop. Everything else should go straight across.

Technically all you need to get hashing is 3V3, RST, RX, TX and GND. With PLUG tied to the appropriate rail.

I think I dont realy understand what it is about. Can you explain please. Is it mean,  there will no correct information of temperature or information from PLUG to ctrl board will not be send at all,  if I will not connect correctly?

But fan control is in last firmaware. Did you mean first firmware? Reboot miner to defult settings (small black button near ethernet cable) will help?
