so pull the unit and debug it at a bench. this has been the traditional method of working on large scale cluster deployments for decades, why do it any differently for mining? Commie's example is the ideal way of running a large group of mining rigs.
because pulling the unit with two PSU and (insert the number of GPUs) is a job for two people hehe. besides pulling out and putting back in is a waste of time. look at what i said above, i fixed my hanging rig faster than you can pull that bar bell from a rack LOL. |

then that case will not protect those rigs from dust. it is not just cards that needs cooling, a specific area in the (motherboard, PSU, memory) where temp rises can cause discrete electronic components failure, it can cause issues. that case may look like it can push a lot of air, but can the PSU breath? (like putting your head out of the car window when the car is running fast, air going inside the nose is harder), server PSU designs are rack mountable friendly. but too much hassle hehe....rack and zip ties are just around the corner waiting for you  Take a look at the pic below, another manufacturer (yeah, I know it's going to be huge LOL, advice on resizing is welcome). Square openings (intake) are covered with G-3 filtration material, if needed. So cool dust free air flows through MB and PSU first them being pushed through card radiators that are flash mounted to plates and all gaps are sealed. This particular one isn't that great IMHO as all 4 cards sit on one plate (serviceability), but other manufacturers use separate plates for each card. https://forum.coolbox.pro/images/Landing/42.jpgyup it is not great, you don't know if one of those four fans failed because they are too deep in the case. meanwhile, i go inside my mining room walk around and roll my eyes and i knew a fan failed or not, even better i can pluck a fan(not spinning from a gpu) from a running rig and return it clean and oiled. also just right now, one of my rig hangs, i go inside the room with a gpu riser board.. i "mini miny moe" at the three gpus riser...voila i changed the right one-first try LOL. I sure see your point, but... better the equipment less often it fails, right? These fans are semi-industrial grade, quite reliable, plus you'll sure notice slight temperature rise if one or the fans fails. Besides, some of my friends have their mining farms quite far away from them and monitoring solutions for these farms are developed long time ago (not pricey, too). Other than that... Well let me ask you: if one of your RAM board stops working, how fast will you realize it? Happened to my PC one time and I only noticed half year later that it reboots with 12gb instead of 16 LOL We don't want to constantly monitor everything around us with our own eyes, do we? PS I use risers with LED for that very purpose. instantly if you are using 1 RAM module instead of 4, it was a luck that the rig boots at 12gb without hanging or restarts. it is always better that a component fails totally instead of being a nuisance trying to be working. yes the better, the less often it fails but shit happens specially when there are many points of failure. I got risers with LED too, LED will help with power supply issue to the board but how about the IC or capacitor in that board?, they can fail too and cause issues without the LED warning you. |

outdoors?
2nd fl and 3rd fl? 10-15 meters above ground isn't dust proof enough.. i don't know if you are running them at the 10th floor or higher but it all depends on the environment where we live, it is up to you to discover that.
you can try dust filters but it will affect airflow.

Let's say it can fit 96 cards, the whole lot will still depend greatly on the mining room temperature..can fit 96 cards bit can run at good temps at how many cards? No matter how fast those fans are and the air can pass through that case, if the room heats up...first, humans cannot operate long enough inside the room and second, electronics fail. Now....the cleaning part and the troubleshooting part? Hehe Just cool the room and make everything accessible by hand and easily observed by eyes. anyway if you want your rigs to be as dust free as possible you're going for an air conditioned room, but if you are on intake and exhaust fans no case can protect your rigs from dust. |

A rack and zip ties is better,.
The whole rack is the case, depends on how many layers is your rack will determine the number of rigs will fit.
And to think bigger, the whole mining room is the computer case, you cool the room the more rigs you can run.

I have a QuietCool attic fan in the garage window. It came with a variable speed thingy and thermostat. I have it plugged on a normal smart plug that I can program on/off times. https://quietcoolsystems.com/attic-fan/ Bought it on ebay, the green one. although its better to have the normal red one I think and add your own thermostat / on / off system. Although they seem to have added that on their new models ? Made in USA, nice fan, good build quality, actually pretty quiet, low wattage. so far 3 years almost 24hrs/day except 2-3 months in winter no problems good as new. Those fan and ventilators don't have a gearbox since they are fixed in one direction, not in my case..by removing the gear connected to the rotor, it becomes a simple fixed direction industrial fan..weak link removed hehe. Anyway i have a spare coming, will remove gear too. At full speed, starting capacitors don't matter much unless the fan is hard to turn at the start. |

being a miner requires you to have electrical know hows, same with knowledge in computers.
keep learning.

it is better to have two instead of one bigger intake industrial fan, when one of them fails at least the farm can get by while the other one is being replaced or repaired.
- always have spares
- always have extra capacitors, they are easy to replace
- it is better to have those industrial fans running at full speed, because even when capacitors fail there is a higher electromagnetism(at full speed) to get the rotor to start rotating, if it did not rotate it can burn the windings or just trip the thermal fuse. in any case it is always better that it keeps on running. the only time it will fail to start is if the bearing is in degraded condition- the higher electromagnetism can't slowly rotate the rotor. (happened in my farm, so that's why GPU temps are getting suspicious here hehe)
that fan ran for 3-4 years all through out the bear market and in the later part i knew the starting capacitor is dead, but the bearing is okay so i just left it. will try to replace the bearing and capacitor, but if it becomes a nuisance for repair i'll just throw it away.
update:
the culprit was the gearbox with hardened grease inside and weak starting capacitor, fixed it by removing the gear connected to the rotor... now it is just the three, stator, rotor or bearing, who will give in first? hehe...i knew a failing bearing will have some weird noise but none so far.
didn't replace the bearing, although it is not in pristine condition anymore, i think i can squeeze a good 2 or 3 years more from that.
removing bearing needs a press, hammering might compromise the frame or the new bearing or my hands LOL...might bring it to a machine shop in bear market when i have time.

LOL, this bullrun looks pathetic for GPU miners haha last cycle: we bought the biggest and baddest GPU (1080ti), and then we scratch the buying/building itch by buying one after the other. this cycle: shuffle on mid range GPU?  Actually this is better. So far it appears to have way more staying power this way. I rather a forced slow gear acquirability for miners than too much too soon. I think the gpu shortage and chip shortage it preventing the diff from growing to 650th Last I looked we were at 440th if that's actually the case...for me, I also appreciate the situation hehe  Well it is easier to think this if you have 60+ cards mining with most fully paid off. And if you still have some older generation cards running, it takes more time for them to become phased out/out classed/not profitable/not worth the space and time-due to higher efficiency/hashrate of "new generation" cards. |

cross post tip BTW in cleaning your cards that has a bit of oily/grimy thing in it, better use a tooth brush-like that are thick (plastic) the kind you can find at hardware stores, it will more like throw/sprinkle the dirt away from the components, while thinner-real tooth brush will just squish the dirt around and an air blower can't do shit to grimy dirt.
no problem if you can't get the card squeaky clean from oil- that's not conductive, the black-grime-dirt is what you need to remove.
cards now have very small components unlike the old days but thick brushes can still clean it.

it is a feature to resist ASIC dominance, not completely but it did well.

As long as you make money...it is still a thing. Actually it is applicable to anything where you can make money--"IS A THING"
You aren't making any money until you make your ROI back in a short term possible, this is what makes mining sensible, just because I'm making some dollars everyday doesn't mean I'm in profits yet no pain no gain |

nice work on windows 7! @Zminer777 just noticed that there is no need for system ram to follow ETH DAG size. i was using 6gb and and 8gb on my rigs. i found out in one rig with version 2.45 works with 4gb when i was troubleshooting the RAM BTW the issue was a reduce hashrate when using system ram lower than the DAG size |

So I had a few people scheduled to come and pickup some of my GPUs this weekend. Then all of a sudden one of them says he is not interested, then a few hours later another guy says he doesnt want the GPU anymore. Then a few minutes ago some other guy cancelled. This is very strange.
Then I look and all of twitter and reddit everybody is talking about EIP going live in July. So does this mean the GPU prices top is in?
I read the EIP 1559 and honestly how does it work exactly? I don't think it means that gas fees will always be lower. What about during spikes or Defi craze like we had a few months ago?
It seems like a perfect way to benefit ETH holders and screw over the miners.
weaklings..they come and go as usual |

LOL at video card prices. anyway I bought a nice car amplifier(upgrade to the older one), this thing cost around 400$ much better spending than another gpu in the farm. 12v from ax1500i (inside the PC-modified wire going out) to power this amplifier to a sub and stereo speakers, voila...those department store PC speaker system (however high end it is) is no match. night and day difference |
