Question How much downward air is safe for a PC motherboard? How much CFM is 2 much?

[reaper89971]

I am wondering how much CFM would be 2 much if the fans were blowing down at the motherboard into the case.

I don't think there is a number that would be "too much".
Not in any consumer buyable space.

The only consideration might be budget.

I mean...if you put it in a NASA wind tunnel, maybe you'll have problems.

You mean physically damaging the motherboard due to the airflow? LOL, I don't think there are any off the shelf fans that can do that. Not even the 6k rpm industrial delta fans can do that.

Just make sure all the wires are secured well and that the large air flow isn’t opposed to air flow generated by the CPU or GPU fans.
