Is a nice rig compliments the liquid cooling does not improve the situation much in my opinion it is not worth it and it is also very expensive maybe add some normal fans, and in any case it must be moved from there that position is not optimal
Thank you!
I think a right solution, should be to move the rig in front of the right window with the big external fan blowing the hot air outside.
In the summer i will move to another house, so i can leave the rig in front of the right window, without any issue.

Is it dangerous that your mining farm is located near the window? Rain and wind can hurt you a lot.
It seems to me that you have a very unfortunate mining farm configuration for your hot climate. In the summer you will have big problems with overheating. Or you will have to constantly use the air conditioner.

Thanks for your advice!
I could move the rig in another room, just in front of a window, but i have to take a very long lan cable to keep connection stable, because the router is in my living room, where is the rig now.
Can i use wifi for mining?
I read that wifi is not stable and realible for mining, right?
If i take a 20mt. long lan cable, do you think the size could cause some issues for mining?
Thanks again.

So you mean buying a cooling system, is not worth it for a big rig, because it is expensive and with standard fans, similar results are easily achievable.

most often that is correct.

your room could use 2 fans

I would try this below. Also what is the white unit on the right ?

The box to the right is a big and efficient heating fan, but it is totally disabled since i have the rig, obviously.
The window is not to the top of the image, but there is one on top of the right heating fan and another one, 5 meters about in the opposite direction, so in the direction of the bottom of the image.
So the single big external fan(on the back of the rig), blows all the hot air towards the main window and, for now that the weather it's cold yet, it keeps the environment perfectly confortable.
Indeed, nonetheless keeping both the windows open, the very big room temperature is softly hot, however and this allow me to totally turn off my home heating system.
This is a clear money saving, in the cold season.
The problem will arise soon in some months, when the weather will be very hot(south Italy, Calabria) and then i think i will be forced to keep my air conditioner always on.

This is an image from the back of my rig, where there is the external big fan and here you can see the 4 little fans on the top.



I ran all the cables from the outside, as you can see, so that there is no barrier to the hot air flow.
Just to give you an idea of the size of the environment, this is my living room and what you see in the following image, is about an half of it.
You can see the rig in the bottom left, very small.

I can buy this EVGA 3090 for its present price of 1749$, fair enough since its a prebuilt card, no need for extra cooling problems, my 12 gpu rig takes only 840 watts and gives me 320MH how cool is that? Just commenting on your 12 gpu rig taking 1500watt, what type of gpu are you referring to...
These are my gpus and subsequently is the total power consumption.





The 12th gpu is about to arrive, but i have a gaming laptop too, that i use to mine constantly and has an hashrate of 37mh/s and keeps an average temp of 62°.
So my hashrate is near to 600mh/s, for now, but it will raise near 650mh/s in some days with the 12th gpu that is a second 6700 XT.





And this is my rig.
Yes, my hashrate is almost twice as high as yours and so my power consumption is exactly twice as yours.

Hi all,
do you think such a water or liquid cooler is effective in reducing heat generation in a 12 gpu rig?
Do you tried one of them and can you give mi some recommendation on this topic?
Can it really eliminate the need for fans?
Thanks as ever!
Recommendations are best given before buying. Water cooling for a mining farm of 12 video cards will be very expensive. I always prefer to choose thin graphics cards that can be cooled in the summer with ventilation.

If you have a good price on a prebuilt card. such as this one:

https://www.evga.com/products/product.aspx?pn=24G-P5-3978-KR

you could build a new rig.

But you have a solid 12 card rig and it burns over 1500 watts

the laws of physics say 1500. watts are 3.412 x 1500 = 5118 btu

https://learnmetrics.com/convert-watts-to-btu/


water cooled rig burning 1500 watts  will make same btu, but it will be shifted to the radiators. you will still need to get the heat out the window.

you are in Italy if it is south Italy it is hot in the summer you will need fans to move the heat out of the room

Yes bringing the heat out of the room is most important. We use only 2 50cm exhaust fans for 14 rigs and this bring down the room temperature by 10°C and some cards go down by 15°C.

I can run my 6600xt´s at 0 - 25% fan - so very low noise and i don´t see the point of using water cooling. the cooler for a gpu is to expensive - for fun ok - but it will extend the payback time very much.

What do you mean with water cooled? By a normal water cooled system you have a radiator to dissipate the heat, this way you still need fans on these radiator. Other thing you can do is a submerged system. But a far as i know you still need some movement of the fluids in the tank with some sort of pump or fan.

The effective heat a rig will generate is the same because the Watt's the rig consumes stays the same. You only move the heat away from the source more easily. So it stays cooler.
