L7 Heat issues? maybe? help!

Hey guys ive been around for about a year now. have dabbled into mining. first gpus. and then box asics.
So i figured id dabble into the big boys and got 2 L7’s.
My idea and thought process was to set up like a hydroponic tent system to push cold basement air in. and pull all the hot air out a 8inch exhuast.
I have all of my miners in the tent which is a 5foot by 6.5ft.
4 mini doge, 2 L7, and home tower.

when i run everything i have to fun the fans full blast to push and pull the air. and that gets them to around 84c

If you guys have any suggestions on how i can lower that heat that would great
Or every fellow L7 users. what do yours run at and how did u get them to the temp they are.

Any questions or need for more information ill totally supply just ask!

Thanks everyone!

So the issue here is the hot air being recycled into the tent faster than the air being replaced.

Airflow would help a ton.
Vent the exhaust into a hot box. Vent the hotbox out of the house.

This made a huge difference in my Temps overall.

I have an intake fan shooting in 70 degree air. And an exhaust shooting it out an 8inch dryer vent. The air has to be cooler then that?

The issue is the exhaust heat from the miners are being allowed to cycle back into their intake with the “cool air”.

So if you want to see a drastic drop in Temps you just need separate the hot air from the cool.

Right now your cool air is mixing with your hot making your cool air less cool.
Then you are venting out everything inevitably venting out some of your cool air as well.

You want to make it so the hot air stays contained and only that air is vented out.
While the cool air flows over and cools the miners.

Hi,

We are 3D Print Shop 4 U. https://3dps4u.com

We design and print ducting that is designed to mount onto an ASIC miner to help you control the hot air and reduce the noise some.

We have provided ducting on eBay now since Jan 2018 and have a 98.7% positive feedback rating.

We have just expanded into our own website off eBay, but still operate on eBay.

We normally ship within 24hrs for smaller orders, please allow extra time for a larger order.

We have several designs for current ASIC miners including the Antminer S19 Pro or Goldshell KD5 etc, we also carry 120mm and 140mm Ducting.

We just had it confirmed that my normal 6/7/8" Double fan design will fit the new Antminer L7’s.

  • Click Here for 6" *
    Click Here for 7"
    Click Here for 8"
  • (We am hesitant on selling the 6" for the new L7, The air flow restrictions are untested) The 7" and 8" have minimal restrictions on the air flow that it wouldn’t be a factor. As for the 5", Please if you are putting these on a L7 buy a bigger ducting system. We are sure the miners would overheat if you used the 5".

We have just finished playing with a new material which is HIPS. Which can withstand consistent heat up to 80C/176F.

We can design custom ducting for specific machines if we don’t have a design currently for a miner. All it normally takes is one quick measurement.
