Be careful about this place. Somehow I "won" a raffle or something and it came to over $26000 USD. I had to go through verification process which took 2 days which makes users believe it is real. Then when I tried to send some BTC to my wallet it gave me an error and indicated that I had to make a deposit worth around $1k first. I NEVER had to do this with an exchange. NEVER. Here is what the Discord message looks like. This is what the Discord channel owner wrote:

And this is what the page looks like. Too bad it is not real!

Just for this room there are only 6 rigs. So I just lined them up perpendicular to the window (hot air just blowing out) then used some pieces of cardboard on the left/right sides to direct air flow right to window. That worked well. And I'm using much quieter Noctua fans, and not those Jet Blasters as I call them. ( those loud stock S5 and S7 fans). Temps were good. I did notice when I did my candle smoke test on how much hot air spews out of the tops of these. A stiff long piece of cardboard right over all the tops extending right out to the window screen. Temps dropped 1-2 degrees just doing that. I just wish my stupid ass did this during the summer, but I was so busy doing other things never got the chance. If I need heat, all I need to do is flip the fans. To me that's easier then reversing the miner itself. These are just my test/home ones, others are offsite. Just re-arranging a little makes so much difference. And cost nothing.
 

That kitten is like, this shit is mine and I know I'm cute as hell...so let me take a nap.

To get them hot though you need to mining- then the electricity goes up.

Mining is not always profitable. Effort, as you mean "money" into it. Move to another city? That's a huge incur in cost, just slap that onto the negative balance. Home improvements, expensive. More negative numbers you can add to the balance sheet. Lots of people on here have the bitcoin delusion syndrome. No matter what you tell them, prove to them, even if they just paid $800 in an electric bull for one month at home, mining will somehow make them money. I've seen it with lots of folks on here that have drank the kool-aid.

This is what I'm thinking. Lining up all the Sx's in a row, side by side and just cut a hole in the side of the duct host and put the miner output right in there. With a push from a small fan it should direct all the air flow right out or where I want it. Sorry for the terrible representation. Basically just need one long hose and some cheap thermal tape to close the gaps. Don't really care what it looks like.

Anyone use duct hose to expel the heat from multiple S1-S2-S4-S5-S7 miners out a window? I'm trying to figure out how to connect/join everything together and use the whole opening of the window (residential standard US) for the heat output. Maybe just to keep me busy.
Looking for pictures/ideas. I know there must be someone that has done it.

Good suggestion. Have yet to try it, but good idea. A good enough fan to create some air pressure sucking out is good for hotter days. Colder days can just reverse and get some heat inside.

I ran the SP120 High performance on my S5's and they couldn't cut it. Ambient temps were about 65F and the temps went straight to 65 or higher. Soon as the warm weather sneaks in, those fans will not be able to cool it sufficiently. I opted for the Noctua NF-F12 3000. Used two of them on each S5 and brought the temp back down 10 degrees. A lot less noise than stock fan, but not silent either. In between, but dooable in situation.
Good luck!

Those Delta's spec at 53dB. I wonder if two Noctua's are more quiet than those two Delta's. I'm running two Noctua's 3000's and they are around 2250 rpm and are pretty quiet. I do have a sound meter to test with later when I have time.

That would be nice to have when your power supply isn't %100 modular and the power cables were built into the power supply. But when you have a main power switch on your power supply, I'd rather use the paper clip and the main power switch. Having two redundant switches doing the same thing would confuse some people after a few beers.

What is the white large hose doing behind the S5? Exhausting the hot air? The stock fan on the S5 keeps it cool without any additional fans. Maybe overclocking?

The S5 stock fan probably blows at 250CFM, and is loud. If you put your hand behind the miner you can feel the push of the air really well from that one fan. If the ambient temps are 60-75F I would imagine the fan runs at 3000-3500 rpms and  keeps the temps 48c/49c which is exceptionally good. If I can find a 4 pin fan underclock/undervolter I would give it a try. The stock fan is working way too hard when it doesn't need to. About the noise. If the S5 is in line of sight to your eyes you will definitely hear it and it may bother you after a while. But if it is in another room that is across another room with a turn where you can't physically see the miner then it sounds completely different. Much more tolerable on the ears. Either way I'm replacing all my stock fans with the Noctua NF-F12 Industrial 3000 model. One fan one each end in a push pull config. Take about 20 dB away, but is not silent but MUCH more tolerable. And if in a basement you may not even hear it.

P.S. do not insert filters or anything like that. That will restrict a lot of air flow on any fan. Just don't be lazy and keep your rigs clean. When they need a cleaning, I take them outside and use my air compressor to blow them down and dust them off. Shiny like new.

When you ask Spondoolie about it they always come back with, "Can't talk about it, NDA". So who knows, if they are silent about a mining center going up in flames with their products in it, kind of makes you think a little. I don't think anything was insured and the owners lost everything. If it was arson, that's really terrible.

You need this 24pin connector. Just install the correct pin placement and plug it right into your power supply where you would your big ugly power cable. I do it all the time.

I wanted to try other Delta's also. What model(s) did you get and try? Are you using the stock fan plus another 38mm as the pull, which is a Delta? Which model? There are so many.

Even though I'm switching to Noctua's I'd still love to try and slow that stock fan down a little bit. Working harder then it needs to. Slower fan = less noise.

I know what it was! It was the sun reflecting off that floor that started the fire. Sorry, don't mean to joke, but that floor must be the cleanest, shiniest floor I have ever seen in a data center.

Pokey, did you tape/cover the bottom fins on those S5's? Lots of air escapes from the bottom if you put them on a bread cart type cart. Can easily use blue painters tape or something. Not talking about a huge difference in temps, but a difference. And every temperature point counts for the life of the miner.

We are all delusional. Now, since bitcoin is in the dumps and most people are losing money actually keeping them running we start to call them our heaters in the winter time in the US. It's like we make up excuses to keep them running when we all know an efficient heating system in a house is much better hear then a few electrical spot heaters around making tons of noise.

O stop your whining. You aren't paying for the electricity so stop it. They are obviously setup at your work or somewhere. At least that's what I think?
