For the calculation, it would be about 20kW of hardware.

You are referring to the 3D drawing with your answer, right?
But I would also need to make gaps, so that the air only goes through the miners, right?
If we take my initial design, wouldnt that be somehow similar, even if not optimal?
I mean, I am going for a simple solution. The ceiling is not really good to mount anything on it, I would need to support the duct with columns. Even the lamps were a pain to mount because of the structure of the ceiling.

Just saw a disassemble on YT. The TUF seems to have already a lot of pads and a dedicated little heatsink on the memory. I dont know if you can achieve very much by repadding.
Maybe the way to go is to put some copper fin elements onto the backplate?

On the ASUS TUF?
How thick were the pads you used?

So that would be a 3rd option.
Problem is, that the room has several carriers at the ceiling - like 15cm bumps. Could hang the piping unter that.
Also, due to the pressure lose within the ducts, i would have an over pressure in the room because the exhaust fan would have to push air through several meters of ducts.

Would need to split the room anyways since it is too long.

But would it make so much of a difference?

I mean, if I such out the air of a 65m³ hot room with 8000m³ and supply on the cold side the same 8000m³ of fresh air, would that not be enough? It is an air exchange of over 2x per minute. Because it is easy to install some insulating panels to split the room. but not that easy to install meters of 500mm ducts hanging from the ceiling.

Hi thanks for the reply,

I can not mount the exhaust opposite to the window, because it is a basement and there is only this one big window.
Also, guiding the intake air to the bottom with a fan in front and sucking the hot air from top using 10 fand to blow the air around in the room, is actually my concept as of now! but the air just mixes and gets quite warm altogether. In winter fine, in summer too hot. So i thought of making the room smaller. It is like 15 meters long, thats too big. I am using only 5-6 meters for rigs anyways and there is still room for more. I could may out my power without using even half of the room, so since I use the from area for storage, it would be nice to have it not so hot.
Leading again to my above two options...

We might need some qualified comment from a tech person though.
Maybe we should consider downclocking the mem!?

So here are some examples:

Re-padded Gigabyte OCs 3080 with Thermal Grizzly 8 Pads:
98°C, 98°C, 94°C, 96°C

Stock ASUS TUF OCs 3080:
100°C, 104°C, 106°C, 104°C.....

I dont like that. Should I consider doing a pad replacement on the ASUS, too? Worry about warranty.

Hello,

I have my rigs in a basement room with a window. The room itself is 150m³ (yes cubic meters) big. On the one end there is a high window, like this:


At the moment, there are just 2 fans. One fan pulling 2000 m³/h in through half the window and one fan pushing 2000m³ out through a pipe out of the other half of the window. Due to the pipe pointing to the side outside, the air does not mix outside.

Now I am planning to optimize the airflow and separate the room into a hot and a cold side. I have thought of two options:

(The grey box on the bottom is a door.)

At the moment I have all my GPUs in oben wire shelves hanging. Both options would leave me the possibility to cut holes into the separating panel, to use it to push exhaust air directly through a rig os ASIC to the hot side, if needed.

What do you recommend and why? Any other ideas or hints?

Thank you very much in advance for any advice!

Hey guys, how do I get the settings to stay after a reboot?

I checked the recommended cases and looked a bit around. I thought of maybe combining 2 cases with one mainboard. Since I am going to stack them, I could build 12 GPU rigs with 6 in each case.
Did anybody do this? or are there maybe "two level" cases for 12 GPUs?

Are deltafans and server cases the better way to go thermal wise? Because I could also just put the rigs in smaller stackable open air frames and enclose them in a custom built tent with a top exhaust cap connected to the vent. Fresh air could be just blown into the room, to use the cooled down air of the basement on hot days.

Hello,

at the moment I have about 100 GPUs in a basement room with only one open side (former window) that serves one half air intake, other half air output with each having one big radial fan.
Temperatures get a bit uncomfortable in summer though. The room is about 150m³ big and I did not separate into cold/hot side because I have open air rigs with 12 cards each.

Now I want to put the cards all in server cases with delta fans and solve the temperature problem once and for all.
Can you recommend some good cases? Most of my cards are 3 slot height though (and none are blower style cards). So that's a problem with some configurations. Since I am not restricted to have them fit in server racks, the cases could be custom sized. But I barely find cases that fit 10 cards or even 12.
I tried some years ago a case with Vegas but they did not ventilate enough due to the small gaps in between them.
I am looking for small footprint, stacked, maximum airflow, high service convenience. So I can stack them, connect the intake air so the cold side, the other vent to the hot side and end the struggle in summer.

Any suggestions what I should look for?

Thank you in advance!!

Whats the OC kernel and how does it work? Ver 1.58

Am I just unlucky with my USB sticks, or does the Zig eat them? I needed to replace the USB stick every 1-2 months because the hashrate gets really bad and I found out a fresh USB stick helps. Reimaging the old one does not help.... Any ideas?

Mine ran stable on Groestl on suprnova.

What is currently the best option to mine with these? I checked Nicehash vs. ZPool vs. Zergpool. It seems Zergpool on Qubit performed best so far the last days. But now it seems not to find Blocks. Nicehash was consistent, but lower profits. Zpool was way behind profit wise.
