Hello guys,

I am searching for help regarding cooling for my mining room.
I have tried to reach out too the local stores in Norway, but people dont have the experience with this.

I have uploaded a photo that illustrates the room and also what kind of gear i have.
If anyone of you can help me out, it would be great.

What do you guys think is the best way too cool the room down?
The room is 3x9m.

As is always stated in these threads, it's not about cooling the room as much as it is about removing the heat.  Use ducting to get the heat out of the room from the miners and make sure you have a clean intake solution.

Without doing the exact math, your probably around 5-6000 CFM of air you need to displace.  The arrangement will depend on what you can do with those exterior walls but the general rules still apply, bring in a ton of clean air (filter the intake) force it to move through the miners to reach the exit, and discharge at least the same amount of air at your exits.

Without seeing the details of your racks, think your going to need several large holes for intake on one exterior wall and several more on the other exterior wall.  Ideally you block the room off with the miner racks to force the air to only flow one direction.

well if are speaking about your room size I think the best and easiest way is to install air conditioner for 40-45 sq m2, it will be 2.5 kw model.. such conditioner is enough to cool room with 3 rigs with eacj 7x 1080ti cards..
or you may install ventilation system, but that is kinda a totally different story

The key point in making ventilation plan is: separate cool air (intake) and hot air (outtake), dont mix them. One of the best solution is using ducting which is not that difficult to make the routing plan because most of your miners are asics.

one important factor here that is unknown is whether the ceiling above you is also the floor of a storey above, or is there a roof above it? If you are on the top floor it's very effective to route the hot air up that way, and bring the cool air in via the external walls.

Crypto currency enthusiast and miner since 2015. Mined approx 200 ETH during 2016 and 2017 and sold it at approximately $US40 each. Then I watched it reach $1000+ each. If anyone bothers to read this stuff pay attention to this: HODL HODL HODL HODL HODL HODL

I started mining with 1 AMD 7950 and 1 R9-280X. Then I gradually built my AMD operation into 12 R9-290s. Awesome ETH hash but ridiculous power consumption and heat. Over the last year I defected to the Nvidia team. I now use GTX 1070s. They were expensive to buy (probably a bargain now) but awesome hash rate vs. power consumption. blah blah blah blah

35000W power is 35000W worth of heat that needs to be cooled; getting an AC to cool that is going to be very expensive.

As the people above have said, you will need to separate the cold air from the hot air and ventilate it outside.

This is what I've done in my mining room

https://ibb.co/mBEbQ8
https://ibb.co/b1tECo

I used 2mm plastic sheets to partition the room from both sides; so basically my room is now partitioned to 3 sections (Right side: hot air, left side: hot air, middle section: the miners and cold air).
The outer partitions (right and left) has vents on the ceiling to suck the air outside.

Its a bit costly to set up, especially the vents/ducts, I'm sure it can be done in a cheaper way.. but it saved me alot more on cooling and the power consumption that I would've otherwise spent on additional ACs.
My setup is a bit inefficient, as there are some spaces open in the plastic sheets where cold air is being exhausted without going through the GPUs (such as the spaces behind the motherboard and empty sections of the rig frames).

Edit: just to give you an example of how much it can save you on cooling spends.

My rigs consume around 45000W; theoretically, without separating hot/cold air, I would need 45000W worth of cooling power (or 155000 BTU AC).
My setup allows me to keep my gpus constantly below 58 degrees with only 72000 BTU ACs (21000W of cooling), the ACs consume around 8500W of power. Otherwise, I would've required twice that amount of cooling.
Where im operating, the weather is at 42C right now; so this is kind of an extreme scenario; where in your country, you would require less than I do
