Recently started mining and have been adding cards.
Right now running (3) 3080s and (1) 6800. I have a 3060 not in use right now til I build a rig.
All but the 6800 came in prebuilt PCs.

Summer is here and so are the triple electric rates during pak and double rates at mid peak times.
Also the house is getting hotter and so it the garage.
I am wondering what others are doing in the summer to keep mining and beat the rates and heat?
If I mine in the garage in 100*F it is stressful on the cards and PCs. If I mine in the house its hot as hell inside and that makes AC work even harder and wife is complaining about the heat.

I have thought about putting them in a tent in the house or garage with a small AC.

Anyone have any ideas to share?

Four cards shouldn’t be overpowering your A/C.

I put my cards right next to my HVAC system. It helps dissipate the heat throughout the house when the HVAC turns on. Keeps any single room from becoming too hot, and works great in the winter to help spread the heat through the house. I have 9 ampere cards running among two machines and when the A/C is off the basement can warm up - but when the A/C is on it can cool it right back down. I had a friend down in Texas who ran his six card 1080ti rig in a padlocked wire dog kennel outside in the shade and rain protection of his condo porch. It did fine all summer, just had to blow it off occassionally

HVAC is on the roof and intake in the hallway ceiling.
But HVAC isnt working and we have 2 small window ACs and I portable AC

EDIT: What cards does your friend in Texas have? Are they 3080 or 3090s and taking the heat?

1080ti as I mentioned

He has a box fan pointed at them and they took the Texas heat outside all summer. Do note they were on his covered porch. So no direct sun and no direct rain.
 
I am in MD, temps in the 90's at times during the summer.

All my miners are in the garage, with a vent fan in a window. They don't get A/C, but constant airflow. Consider that inside of a typical computer is warmer than outside the case, and that a normal office might be at 72 degrees. Inside the case will be a bit warmer, lets say 80 degrees for a good case. Having GPU's under constant airflow at 90 degrees is not much hotter. Fan profiles and voltage/TDP limits to keep power draw down along with temperatures and it is pretty okay, and a lot cheaper than using A/C
 
I dont have any windows in my garage, but I cut a 6" lohe in the ceiling last night and installed a 6" server fan to vent into attic. Ill work on more measures next few days and get them out of their cases.

Can anyone recommend some good risers that wont catch fire or have issues?
Hard to decide with every brands seeming to have catastrophic reviews.
 
I just connect my risers via pcie power cables. Just get a bunch of pcie cable splitters so you can power twice as many, also makes it easier to connect. The risers I buy are unbranded ones from ebay but they're black PCBs with red PCIE slots and seem to be working fine.

I have one rig in the garage, core temps are between 62-77C. It's in a server case so airflow could be improved.

I like the idea of doing a shed if you have the space. You don't really need AC as long as you're exhausting all the hot air and pulling in fresh air, and then you're not messing up stuff in your house. Running conduit could be expensive though so for now most of my stuff is in the basement. Previously I had a lot of stuff in a rental trailer and used some 6" piping from home Depot to exhaust the heat out the windows. For GPU rigs, a grow tent with intake and outlet fans can help you direct the heat where you want it and prevent spillage into the house.

Yeah I think I could try that The grow tent with exhaust out the window.
I'm looking at the Ubit risers right now. I only have 5 gps so price isn't a huge deal.
Might need another PSU though since i have prebuilt generic one and a750 sff psu and 650 watt EVGA

If I did 2 hoses one in and one out both leading to a window it would work best. That way no cool air from the house is vented out causing neg pressure and pulling in outside hot air
Intake hose bottom tent opening, and exhaust air top of tent.

I may have a grow tent already 😁

This is what I did with my ASICs. It's a little easier with them because it's a single powerful fan and there's not a lot of waste heat going out the sides. This dropped the temperatures in my trailer by probably 20 degrees. Rain and bugs weren't a problem, but if I were to do this at home I would want something more professional and with mesh netting to keep bugs and stuff out (home depot sells those too). Total cost was about $100 and a few hours of time. I didn't really need to wrap any insulation around the exhaust of the ASICs because the 6" pipes seemed to catch it all. Ideally I'd probably have longer pipes with more of an elbow and use an outlet fan in the pipe to pull the air out better and let me connect multiple ASICs to a single outlet pipe.

Blower fan GPUs are nice because you can at least install them compactly into a server rack and maybe direct all that air out the back somewhere, but with most GPUs now having multiple fans where the heat goes everywhere I think you'd probably want to put those rigs in a grow tent and exhaust the heat out somewhere like this. I would think the grow tent outlet pipe could be done the same way, though it'd definitely need intake/outlet fans in the piping.

Were those ASICs efficient?
It is convenient they way they blow straight out the back?
How loud are those server PSUs?
I was looking at them, but saw the multiple small fans and feel like they might be screamers and not good for in a house.

Up to about half load the server PSUs are silent. At full load they are screamers.

These server PSUs aren't loud at all. I can't hear them at all over everything else. The only time I've had one be kinda loud is plugged into a 120V socket and basically maxed out on power. I know people complain about their noise but I haven't had an issue. I'm using 1200W HP models but it looks like the 1100W Dell's are cheaper now (require a different breakout board though). Each ASIC (Innosilicon A4+) is using about 750W. What I'm doing for power is that each 750W ASIC gets one server PSU, and for my GPU mining rigs I combine one server PSU with one SS-850-KMW PSU. With all the extra cables, boards, etc. it works out to about $150-200 for the power supplies and gets me about 2kW of power so plenty for a 6-8 GPU rig of any type and plenty for an ASIC. I wanted to go server PSUs only, but it's a pain with all the accessory cables you need so now I'm using them with a cheap ATX PSU. At the same time, the price difference between a cheap 400W ATX PSU and a 800W or so one isn't much so I usually get a higher powered one so that I can run a few cards off of it. This helps if I'm doing something like 6-8 GPUs that need 200W or more apiece.

Have you considered making the move to Alaska to help with the heat? Pretty sure below would be the ideal situation for what your looking to do. :eek:
I was looking at some property in Montana. I want to make this as hands-off as possible so the remote management shouldn't be a big deal, but I'm worried more about theft.

So if I buy the 2kW servers and run 3 GPUs on each they should run silent lol.
Other news I fixed my Dell that was mining on a 3060. They give you a blinking light morse code to help troubleshoot. It was either PSU or MB. I bought 2 PSUs and that didnt help. Bought a MB and had issues still. Looked into bios and it was set to legacy to boot from a floppy lol. Not going to try miming on that stupid PC again. It will be the family PC to do whatever on or Ill sell it, not sure yet.

Only problem is Alaska's power is the 2nd highest only to Hawaii

Those Seasonic's are cheap for the power they output, Nice find!
Im worried about noise as they might end up in my bedroom in the grow tent instead of growing in the tent. I am used to fans at night, but grow fans arent jet sounding, but lower pitched like white noise I guess.
 
Basically, the main problem to solve here is the airflow - air in, air out. The airflow, if inside, needs to be consistent - pump out as much as what you get in. It's similar to a closed up PC case. (At least that's what I think).
