Number 9! Ninth altcoin thread. Back to the moon Baby!

[molivil]

Most of my gear is open air.

My 1080tis are making over 2 dollars a day.

Not bad.

I sold most GPUs.

My in house is making 20 a day burning 8 so 12 net.

My hosted gear is making 20 a day I split the coins 10 net so 22 a day on paid off gear

.

Open air for the win

The few R7's I own are currently on Dagger Hashimoto, each making around $2.26 on ETH (0.00693 ETH) per day. About 10 cents less on ETC. Power is $0.62, so each one is netting $1.64 a day on ETH. ROI at 414 days. Not exactly great, but it's good enough for me to encourage a hobby. Most of my ETH I exchange to BTC, and some to other coins and patiently wait for a payday to happen.. which, judging by how markets are behaving, may be sooner than I expected.

I like open air and most of my GPUs rigs in the past were all open air, but I agree with the above poster.

Enclosed and closed GPU rigs are better because in the summer the heat won't stay in your house, you basically just use a tube and force the air outside.

With Antminers its easy to force the air outside, you just zip-tie some tubes to the exhaust fans and you are done but you can't do that with a GPU rig thats open air. You can put a fan in front of it and put it next to the window but some of the heat will enter the house. Only way to do it right is to put it in a server 4U chassis and all the heat, except maybe the heat of the case will be exhausted outside and you save on AC costs from heating up your home.

using a short length of dryer ducting; if the inlet is long enough with a few bends, the hum is completely missing.  with the same on the outlet, you can plumb it right to an external vent.   I was able to run an S7 in an RV I lived in;  for over a year.  Never heard it;  Just kept an eye on it.

...and the next challenge is going to be to find enough Scythe Ultra Kaze fans... They seem to be almost out of stock everywhere I look around here. Any other suggestions when it comes to strong 120mm fans to move the air through 4U chassis?

some lower speed deltas are good.

let me find a link


https://www.ebay.com/itm/254276232528?ViewItem=&item=254276232528

these move a lot of air  150 cfm 51db


the ones below are quieter 113 cfm 46db

I use 2 of the lower speed ones in my 1 card s-9 heaters'

this is fairly quiet and pretty efficient.

my buddy wants to send me a couple S9 SE's from Australia....  IF that happens I may actually put another ASIC back online sometime soon...



I do plan on jumping on an R606 or two when I have the spare funds.   Wanna get a few lottery machines set up for my parents;  they have 5.8Kw of grid tied solar at home, and I would use it to run them during the day while charging a battery, and at night, it would run off the battery not taking from the grid like the house does

When I get one to keep at home;  Ill actually work out a battery/charge controller/solar/inverter setup sized to handle a single R606;  This way you can set up an independent 'satellite' miner system similar to the setup my buddy and I had come up with for GPU rigs in 2017.... if you hook it to Wifi;  it would be completely wireless and independent.

open air for me too.

GPUs are zip tied to racks.

the room is the case and the windows are the exhaust.

Started my GPU farms like the above in 2016 and never looked back - ease of maintenance is the key.

Dust is the only pitfall though - I gave up on this long time ago and most of my 470/480 rigs still running at peak non-stop eventhough they are bloody dusty and grimy.

Well ..... as long as critical parts still works fine like fans for PSU, GPU and CPU - will just leave them alone. All of them are well ROIed several times over, so just leave them alone.

I will run all my

gtx 1080ti's -------- 12 left
AMD vega 56 -------- 4 left
till they die.
they are paid off in full multiple times.

the 1660 and 3 1660ti's are not paid off but they do earn a profit

You can get PVC coated exhaust hoses pretty cheap and they muffle noise and insulate heat a lot better than just aluminum alone.  

An example of what i use.

I protected my rig with simple strainer mounted by aluminum tape. It's very cheap and really protect from dust and pollen. Just need to cleaning up them by vacuum cleaner once per week or two

ease of maintenance you say?

how about real time (powered on and mining) pulling off slow spin/not spinning GPU fans and re oiling-plugging back in fans? hehe

no need to keep the area squeaky clean, for me i'm just making sure dust build up does not come close to possible "harmful" level to electronics----> i just come inside the room semi naked with face mask and a blower.. blowing the dust that accumulated in the electronics  (all powered on and mining)

You'll have to provide an image because your description doesn't make much sense.

LOL nice mental image there.

I once thought of using some of those enclosed IKEA clothes racks. They are sold on Ikea (I couldn't find it on their website) for like $25 or something. The idea was to position the rack near a window , cut open holes at the back, near the bottom for intake, and one for hot exhaust at the top. Then place rigs inside it. That way it would be an enclosed system, while still using outside air for cooling. It also wouldn't look insanely ugly.

https://sg.carousell.com/p/ikea-clothes-hanger-rack-207248788/

Never got into executing this plan though. For now I have my miners in the patio with box fans blowing at them.

Most of the Gigabyte RX470s fans died premature death - I had to replace several dozens of them. The Sapphire ones are very good and lasts longer - most still running since 2016. The motherboards (circa 2016/17 ASrock Pro BTC) are beyond recognition - the dust and grime probably evolved into a protection layer for the electronics thus still running until today. I should take a pics next time - we should start a most "dirtiest GPU warrior rig" pix contest.

My wife's office is owned by a cheap landlord who doesn't bother to put a filter on the 60 ton HVACs - consequently I get these nasty little grey fibers all over everything. It got so bad that I weighed the weight of the matted fibers that I pulled out of a 6 card rig that ran for 1 year. All fibers from GPU fans, CPU fan, PSU fan and caked all over the motherboard and wood rig frame came in at 196 grams. That's fiber weight - not counting the dust that I blew out after removing the fibers.

I've had my hands in people's orifices before but this...this was nasty!

In all the years that I was mining. I've never had a motherboard, CPU, or RAM ever fail on me.

The parts which have the highest failure rate are the GPU fans, then maybe the GPUs itself, then the Risers, then the PSUs, then the harddrives.

The most reliable GPUs I've had were the cheap and loud Reference GPUs from all generations. Don't think I've ever had one fail.
The most reliable PSU was probably the cheap $40 Corsair 750CW. Had tons of those and suprisingly it never failed while my Gold rated 1600W did fail. Ironic.

Where was this optimism in jan 2017 when eth was 6 $ and btc ~ 600-1k ?

I might be misremembering but wasn't Bitcoin over $2000 and more like $2500 in that timeframe?

Any other suggestions when it comes to strong 120mm fans to move the air through 4U chassis?

Any of the Delta AFB series in the 140-200 CFM range are pretty quiet - and the AFB series don't have the high pitched whine of the FFB series.
Had a bunch of them in my Innosilicon A2s, kept them when I finally got around to scrapping out the A2s and they're now doing "push LOTS of air through the air filter assembly from the window" duty.

[P00P135]

I use these 120mm 113CFM fans.  Pretty good price for 6 of them.

826-1000  Jan 1 2017 to Jan 31 2017   and maybe it did go lower then 826 that month

I just put those 113 delta's into my s-9 heater project

Thanks for the suggestion, Quintleo. These look perfect. Found some that have more cfm than the Scythe variants at similar dbA rating. They seem to be in stock over here too which could prove useful!
