Hi Guys
I was just wondering what you use to keep your mining rigs cool?
In my case it is just a single 6 GPU mining rig. Are a couple of fans blowing parallel to the GPU'S good enough? Any other, better solutions?
Thanks!
Ideally, have a big fan suck in fresh air that you blow on your rig(s) or int he room where you have them and have another that sucks the air outside. kinda the same way you would cool your house in a hot summer. Air needs to move in order to cool and for that, it must have somewhere to go so you need to create the low pressure (with a big fan for instance). imho, case fans in front of the frames aren't really super useful in an open air case anyway. Their CFM is usually pretty low.
The problem is no so much that the GPUs get hot (above 70°+) since they can perfectly handle it, the problem is to cool the air of your room down, otherwise your cards only have hot air to work with.
In my case, I had 7x 6 cards rigs in a 6-8 square meter room with only a 20x40cm hole in the wall to blow the air outside. So I got a large 60cm fan to blow in fresh air and bought 2x 7" car fans off of aliexpress (quite noise but high air flow) to suck the air out. The room still got quite warm, but at least air circulated.
Also don't forget heat goes up, so put your rigs as close to the floor as possible.
Air conditioning uses way too much electricity to be worth it for most home miners, unless their house/apartement is already cooled with A/C.
