~snip~
it fixed itself thanks
if i wanted to add some extra cooling to the units where should i place the fans top,bottom or sides?
It doesn't really matter that much, the thing that matters is that you need to keep the flow moving from A to B.
That is, don't point two fans into the miner for example, instead, put them one after the other so that the flow continues.

Do this:

Don't do this:

You can try different configurations, top/bottom, left/right, etc, and then measure how fast is the internal fan spinning after you changed something (look at the RPMs). Keep changing configurations until you get the lowest RPMs
