First thing is working with Antminers and pretty much any miner. Today we will work with my engineering and programming back ground. As you know if you read past posts, I am terminally ill, but my mind works just fine. I cannot afford these systems myself, I still have many friends that come to me for help. I read and took courses in asic design and others. Mathematics plays big factors. Temperatures equals amount of hash power you should be using, etc. Running maximum your taking a perfectly great built system meant to last many years.
Today for all you in colder climate range from end of September to early April.I recommend a tablet, any will do. One that is really important is keeping a website of your location. You can live in a city and can be negative 16 and the other side can be negative 10. Can this change how your miner runs and how long it lasts. Yes ! Simple really. Keep your frequency 10% below maximum. Simple rule and you don’t have to work with asic frequencies. Asics are highly complex. Please treat them like any high end electronics. My friends room. I got him to set the miner on a good size tile . Any really from a hardware store. Don’t fry your $2000 desk. Tile should be able to have enough space for miner and two Bitmain power supplies. Use power accordinging. Never to put this system on one 20 amp breaker. Asking for a fire to breakout in actually power supplies. Use a 30 amp system. Will have plenty more for fans to return warm air back out the window.
Have a thermometer and watch it if during the day we go from negative 6 degrees to plus one. You can control this by opening the window more or less. These miners do require your time, especially S9 system and S5s and lower. The same apples to your gpu rig. A miner running totally efficient can last you many great winters. Summers try to stick to buying new cryptos on exchanges. Please leave those miners till it’s time. They will always be used for new coins. Never end. Think you found this out by now. Seen an S3 months ago for $80 and now $500 or more depending on condition. As a previous programmer I always told people hold on to old GPUs. They were built differant and great for FPGA mining. Well Blake programmed. It, came up with Decred. Now valued at a great number. Same with all Blake coins. I read the source. They are written as perfect as many great coins. When I say great, I mean Ethereum. Just a beautiful well written currency.
So back to the mining. Canada, your one, Russia ,2 , Iceland 3, and so on. Even Iceland gets warm in the summer. The States this can be done but with more energy costs, but still I have secrets for you too. Next review.
So cold dwellers. 1 dedicated a bedroom. So you don’t freeze house. Towel for under door, so cold don’t escape, never ever by a bathroom. Can freeze pipes. Do it right and miner will still supply heat to room. 2 temperature gauge. 3. A tablet to read outside temperature and keep and eye on Antminer. 3. Slide or open window according to temperature. A -35 day, miniamize window but not to much. This is where you watch it really well. You can mine many coins. GPUs a nice wireless electronic temperature gauge. Your machines will work primo. All my friends 
thank me all the time and always have great questions.
