Question Power supply air flow

Hi to all,

I'm considering moving the PSU to the bottom of the case I'm building, but I'm not sure there is enough space for proper air intake.

It draws with a 140-mm fan, and there will be a gap along the bottom of the case about 1/8" high, figure a total of about 40 inches in length on this gap, for a total of about 5 square inches of inlet space.

Two questions: Will this be enough inlet space to allow proper air flow for the PSU? Assuming it IS enough space, will the narrow constriction make it sound like a wind tunnel?

I can make the gap wider if needed, but I wanted to get some input from those with more knowledge of air flow than I.

Thanks!!

Better to have a lot of small, 0.5cm diameter sized holes for air outage. One big hole wont be as effective.

Doesnt matter where you put it though, the hot air is going out of the PSU. Hopefully your back case fan is also blowing out, it would be a disaster if your PSU is blowing out and your back fan is sucking in at same time - circulates hot air.
