Mining rig funs blow out to which direction?

[akirafes]

The funs on the mining ring should they take hot air and blow out? (the direction) or should they take cool air and blow inside the rig through the gpu carts?

I'm guessing you are trying to know how graphics card cooling fans works? I believe they blow out any heat generated while mining or doing intense workload,  also graphic cards cooling methods are different from each other

If this is an enclosed pc case then one side should be intake and the other side blowing out.  So all fans face the same direction and work together to move air in and then out.

It depends on the type of cooling the GPU uses.

If your set up is a reference type of blower fan, it intakes hot air from the computer case and it comes out the exhaust which is suppose to be outside the PC case.

If you got a regular aftermarket type of MSI/Gigabyte with large heatpipes and double/triple fans then its different. Basically to make the system as quiet as possible the air pretty much goes all directions, up down left right. What you need to do in a set up like this you need an intake and exhaust case fan because your hot air will keep circulating the computer case.

Since most mining rigs are open air, then it shouldn't be an issue really. As long as the GPUs are kept apart from each other there shouldn't be any issues with cooling.

Closed case you want a blower fan gpu

In open rig - better to blow on GPUs with cold air. In closed rig - better to remove hot air from GPUs. In my closed rig decision - 1 set of fans brings the cold air and due to overpressure it blows hot air out the rig.
