No you should not. You cant seem to control your caps lock key let alone $1 million in mining hardware....

This is the normal operating temp, you shouldnt worry about it.

I cant watch movies while mining on my machine. Thats why you build dedicated mining rigs and dont try to use them like normal computers.


P.S. 4GB of RAM is not nearly enough if you are trying to use the system while mining.

Get rid of that board and buy something else. I extensively tested that specific board and it just doesnt work. I could get 3 cards stable but adding a 4th would cause all kinds of problems and it wouldnt even see card 5 or 6. I tried in linux and windows on multiple BIOS revisions. It is just a shit board.

If you want a good NVIDIA distro for mining I would tell you to take a look at PiMP. I have it on a large number of rigs and it is constantly being updated and worked on. So far it is the most robust solution I have found for NVIDIA mining.

The thermal max for the card is 94c, you should be fine up to 80c but I would shoot for no higher than 75c for longevity.

Any bitcoin(sha256) miner can mine BCH, you just need to point it at a BCH pool.

Look up network difficulty. It will answer your questions as to why your income fluctuates.

I know it may look strange but those are actually both normal things to see. Some boards just have more hw errors than others in my experience, but overall its pretty meaningless. As far as the auto tune firmware goes you are just stuck with it. Some people have claimed that doing an IP reporter reset brings them back to older firmware but I have not been able to duplicate it myself.

This is a bitcoin mining forum you will find no help in this section.

There is no life expectancy for bitcoin miners. They might explode after a month or last 5 years. Chances are by this time most S7s have been ridden hard and put away wet. Plus unless you have VERY cheap power you wont make any money on them. at 10 cent power an S7 only makes ~$15 per month and that will decline steadily.

They make most of the fans for other large companies like Granger etc.

Bitmain has a new repair depot in the US. It should make warrantying systems much faster and much cheaper as you dont have to air freight the unit to Hong Kong anymore.

You have two damaged hash boards. Offsite repair is the only option, there is nothing you can do on your own.

You are not taking into account difficulty as people bring more miners online. Even if the price stayed flat this whole time you would be making less.

P.S. If you are paying that much for electricity you should stop mining now before you start to lose money.

To clear up a few things from the OP.

There is no S7 ever that runs at a stock speed of 4.3th. The slowest release was 4.66th (batch 2).

S7 has 2 fan speeds. ~6000rpm for the intake fan and ~4300rpm for the exhaust fan. Going with fans that dont even come close to this is a very bad idea. The increased heat load will shorten the life of the system.

The real resolution is for people to stop buying industrial mining equipment, running it at home, then being surprised/complaining about the sound. If you want to run them at home, dont run them in your living area. Is it really that complicated to figure out?

I have had nothing but problems with the MSI boards and will no longer buy any. I would return that board saying the ports are bad and buy something better.

Just keep a few known good cables on hand and when you think you might have a bad cable swap it with the known good cable.

Try the altcoin section, L3 doesnt mine bitcoins....

You are going to lose a healthy portion of your profits to those AC units. Those portable types are the least efficient of all you could have used. You should really work out a better cooling system that doesnt require AC if you want to come close to maximizing profits.
