The important thing is the GPUs has no dust, no overheating.

Even if you are mining to get some coin - whatever it is. You can always mine ethereum - get more cash this way and then convert it to whatever coin you want to have/keep.

If air condition does not blow directly into rig then it is ok.
Also GPU can easily run at 75*C. The Max temperature for most GPUs is 90*C and this is too much usually.
Also fans in GPU should not run on 100% so if they are running at 60% then you are all set

I had air conditioner that wat takin 5kW and cooling with power of 15kW.
Rigs that were in that room were taking about 25kW, so air conditioning was cooling but had not enough power. Room temperature was 30*C.
They were running or a 2 years in that conditions and they have totally no problem and running even now almost 3 years. GTX 1070 8GB.

It looked like this: https://youtu.be/F9_2WBalUF8

And you are right, it is clean and without dust.
Currently i have air cooled GPU farm and the dust is there

Actually dust is not bad, the worse are those flying worms which always get somehow in

You have really good set up

1- Your total power 25kw at the wall ?
2- Your AC has 15kw cooling capacity and eats 5kw ?
3- I see you have pipes on the ceiling. do they blow cold air from AC or is it for exaust fan for the hot air ?

I live in a really hot region with %70 humidity in summer seasons.
The dust is a big problem for me. Fan of the GPUs fails after everal months. And yes ! I sometimes see some flying worms in the rigs area.
I cannot stay in the rigs area when the rigs has any problem. So, i decided to use AC.
I dont think about AC price and its eating power because we can use the electricity bill for taxes.
Mining is my hobby. I dont need the profit from it. Of course, i get money but i always tries to mine different coins in different algos.
I want my stuff clean without dust and working in good conditions.
