Have you thought about 2 phases immersion cooling?
After days of research and planning I’ve concluded that in my area it's not a viable option for cooling (money wise).
In yours, it may make sense. Plus it's super cool to use!

You have a few options for cooling.
If I recall, Morocco tends to be dry - in which case "evaporative cooling" is DEFINITELY an option to investigate.
Mechanical cooling (aka Air Conditioning) will cost you appx. 20-25% (depends on the efficiency of the A/C unit) of the amount of electricity you use for your miners.
Fan cooling via massive airflow doesn't work so well in hot (high 20s C and higher) temperatures, if that's your only option PLAN to underclock (and if possible undervolt) the units to be ABLE to keep them cool enough to operate.
Given all of the factors above, I doubt you will be able to profit enough with an S7 to be able to pay back the cost of buying one, even if Bitcoin price takes a BIG runup around the halfing this summer.

You are lucky to have evaporation cooling as an option. I would research it and go with it, cheapest option there is really.
I live in a area that weather does not allow evaporation cooling so I used lots of CFM's from fan's and a good exhaust. I think your country's heat might make this a little bit hard though.
AC you will not be able to justify it's just to high at this point in miniing.
, why you can't use evaporation u live in desert or what ?Evaporative cooling works great where you can easily evaporate water. In essence, you mostly need dry ambient air. Desert would be quite good to evaporate water, aside its average high temperature.
Best places are where there is dry air and moderate temperature.
Sadly this is the case for me we have a decent amount of humidity in the air, so evaporation cooling is not that effective compared to dry air. So my best option which I do is use high amount of CFM to push air from miners and a good exhust to send it away. This is in my mining area I do all this.
When I first got into mining it was GPU's and i used the heck out of box fan's. But I've grown and so have my fans
Have you thought about cloud mining? Plenty of people choose to do so. I personally prefer to have the miners at home since my electricity is cheap and 5 months per year I use the heat to warm my house.
For my first 4 miners, counting heat recuperation I have electricity for about 0.06 $US/Kwh
Where are you from ? u have a cheap electricity you so lucky For my first 4 miners, counting heat recuperation I have electricity for about 0.06 $US/Kwh
I'm from Canada, Quebec.
We have hydro power and good rates to $US. That is why electricity here is cheap.
There is also a plan that I might subscribe to. I need to do the maths but on that plan there are two rates. One when outside temperature is above -12°C and another when it's below -12°C. Rates are 0.033 $US/Kwh for around 11 months and 0.18 $US/Kwh for the coldest month. You obviously shut down your miners when you switch rates.
I'll do some researches on the numbers of hours per year forecasted on each plan and see if it makes sense.
Switching plan would also imply heating my house from another source than electricity (oil, wood or gas). Cost of heating source conversion would also have to be included in my calculations.

forget about cloud mining it's a scam
hashnest as well?
I do not think so...
and what do you think about my U2cloudmining system who makes little profit since it is online?

With Hashnest you pay quite high maintenance (electricity) fees. I am still looking for ways to prove I'm legit. Maybe for a start, it could be in person delivery of hardware. Less scary than sending your box by mail.

Cloud mining is full of so many scam sites it's scary. If you do choose cloud go over to hashnest, that is about as good as it gets.
But I like to have mine myself as I like to tinker with the miners. There is initial setup costs with a mining area but if you are planning to mine long term it is not a bad investment. Keep in mind there is no ROI guarantees.
I would also guess that many people were scammed on cloud mining.
Given my electricity rates and my capacity to reuse heat I would have liked to host miners but it seems impossible until I get that many posts which grants me a better title in this forum.
Meanwhile, I will keep reinvesting mining income on new miners.
It depends there were a few that were legit that stopped due to miners costed more then what they made in cloud contract. So there were a few more, but vast majority were scam.
With sticking with hashnest you know what your getting. And perhaps most important is you can sell at anytime.

in morocco we cost 0.09$ per 100KW/H...it's cheap ou not ?
So 0.0009$ per kWh? Make sure you're not messing up the math and you're not missing other fees. But if thats the case then thats nearly free electricity.
0.09$/kWh is high but not unusual. 0.05$/kWh is very good. 0.02-0.03$/kWh is greatness and anything less would be hyper fantastic for mining.
This could be horribly wrong but a article - https://energypedia.info/wiki/Morocco_Energy_Situation say's "Prices range from 0.9 MAD per kWh for up to 100 kWh / month to 1.49 MAD per kWh beyond 500 kWh / month."
.9 MAD = approx 0.093046 USD
So it is normalish electricity nothing special. But I would check as if site is right it rises as your usage does. And this is old like 1.5 to 2 years so very well could be higher or lower.
Do you have a VAT aswell? It appeared you do there, but that will also make a difference depending on price.
it's exactly nembers that u give, so i think you want to tell it's good price to start mining and build my little own farm ? s
Your power price is borderline to make profit.
Your country is pretty hot.
Cooling would cost extra money.
How do you plan to keep the gear cooled off?
from u ?

my brother i just want to know the approximate number to do some math,
The problem is that the S7 has only existed for a few months, which isn't really long enough to extrapolate expected lifetime from reliably.
It's also a large design departure in several respects from any previous Bitmain miner, so it's not really viable to try to extrapolate the lifetime of a S7 from the lifetime of the S5 (which has only existed a little over a year itself), much less previous Bitmain designs.
There is also a major variation between the batches, some using more chips some less, some apparently pushing the chips right to the limit to achieve the claimed stats of the batch others being more conservative.
9 cents / kwh is a little lower than average compared to the US, but it's not really CHEAP - you have to get under 7 before I would count it as cheap electric, 5 or less for very cheap, and 3 or less if you want to seriously compete with most of the big farms and their VERY VERY cheap electric.
Philipma above may be right however bitmain's recent S7 batches (8, 9 and upcoming) are crap, they're overclocking already from the factory, out of the box. These new batches won't last 6 months. Which is just as good since halving will happen in early July this year. After rewards halve, these miners will become almost worthless. By then Bitmain will have come out with a new model that's twice as energy efficient but will cost you three times as much. We must be stupid to play their game cause we losers and China factory owners only winners. I'm beginning to suspect Satoshi must be Chinese.
What proof of this do you have? They do have less chips which stinks on efficiency. But from what I have seen B8 has been a solid miner. I got one to see what it was like and it's not been up for around 30 day's without touching it.
So get around 4.7T and don't have to babysit... not a horrible miner in my book. And at having they will not be worthless they will be sold to people with less electricity prices... and yes they will get a good compared to new chances are. But that is how mining works.
Look at 2 models back on bitmain on S3s' they still are bought and have a value look at Ebay they bring 100+ . Which is amazing considering how long they have been mining. But as of yet your after having S7's being worthless.. I don't see it.
Do you own a S7?
