I am a bit confused now, which one is correct ? This ?

Yes it runs circles inside the hot room, thus creating pressure against the (asic miner) fans.

or This?

... and the outer wall better have lots of vents (or big enough) so the air can go easily.

What inner wall are you talking about exactly ? I think there is a bit of misunderstanding, here , there is no wall/vents in the inner wall, I think you didn't quite get the idea, or maybe I am too stupid to understand the logic , basically I have 3 walls.

Intake Wall ( Fans and Vents)
Partition Wall (splits the miner's fans , intake fan is in the cold/intake side and exhaust fans are in the hot/exhaust part.
Exhaust Wall (Fans and Vents)

the middle/partition wall is something like this

Intake side

Exhaust side

I hope you didn't think that I am going to put vents in that wall , this will make the whole idea of isolating the room pretty useless, please refer to this topic to understand the set-up a bit clearer.

Oh and BTW, this hot room try to make it walk-able, you'll find it very useful for some unrelated things later. Think, giant clothes dryer

Just don't abuse it and create unwanted pressure lol.

1 meter should be more than enough I guess, that is 3.28F , should be more than good for clothes dryer Grin

Thanks a lot for the all suggestions.

Take into consideration the airflow reduction in any filter medium you use. Also consider how much filter surface area you need in order to accommodate your CFM rate.

Yes the extra vents on the intake side should account for any filtration surface.
