Cooling system for mining rigs, getting heat out of the window

[doslo]

I will be getting my 2 x rigs into 2 cardboard box and getting air pipes out of them to the window.
Power usage is around 1000W per rig.
How powerful fan need to be to get heat from one rig that will be inside cardboard box?
What about width of pipes?
Anyone can share their experience?
Thanks.

Well not to dump on everyone here but 99.9% of the people here for some reason use axial fans - which are great for low pressure gp applications but honestly if you want to exhaust a bunch of heat, you need inline fans - the same ones they use for growing weed.

You think a 100 kW grow room gets cooled with axial fans? Hell no. You'd come back to a whole lot of dead plants lol.

Axial fans are used, but to move air around the room, inline fans used to exhaust the heat.

Rule of thumb is about 200CFM per 1000w

And no, not that worthless 8,000CFM rating on the 20" axial - 200CFM on a inline fan

So I would say a 6" or 8" inline fan, I would go with bigger like 8" if you can handle it - it will make less noise - you can also get a duct muffler which will significantly reduce the noise - trust me these fans can be loud. But they move a ton of air/heat.

Hi, thx for replying.

I was looking at inline fans. So basically 200 CFM is around 320 m3/h.

So this one would be ok ?

Sorry for asking here maybe, but what will be the effect of this stuff on the rig, how much will be the difference in the temperaturs.
For me I think it's a bit expensive spending 160€ in this stuff getting the heat out.
And probably this is going to consume power somewhere around as an GPU?

There will be pipe going from metal case (rig inside the case).  In every case there will be holes for air intake and one for air outtake that connects to pipe that will go to this inline fan, that will get all the the heat from inside the case.
It's a big difference, almost no heat stays inside home.

This takes only around 80W of power.

If you have multipe rigs (every rig x 7 cards, 1000W+ power usage) then in summer with around 30+ degrees (celcius) outside, you can't stand in the room where rigs are and they get really high temperatures.

Thanks to this solution heat will go out the window and cards will be A LOT cooler.
