Airflow in a (PC)-Case
Airflow in a (PC)-Case
(OP)
Good day to you all,
I have to develop a PC Case, and I am trying to get my head around the question whether it would be a good idea NOT to flush mount the intake fan in the bottom to improve airflow/decrease necessary fan RPM.
Since i have trouble describing what the problem, i made a quick Sketch-Up mock up:
Right side would be the traditional way
Left side the "free hanging" variant.
The fans on top are for exhaust.

If my amateurish question is inappropiate here, just ignore me. Otherwise i would be happy to profit from your expertise.
Regards Lukas

RE: Airflow in a (PC)-Case
I'd put 4 feet on the case (like your white blocks) to ensure airflow into the lower fan. Then you'd probably get more airflow with the fan outside the case (and give you more space inside the case to use).

RE: Airflow in a (PC)-Case
but which of these to options is smarter. I am wondering if there is any "free" airflow to be gained with the one on the right.
RE: Airflow in a (PC)-Case
In this case, it doesn't really matter which fan you designate as the "primary" fan. I'd suggest that the top fan blow "in" so that cleaning can be easy and obvious.
In my (limited) experience, electronic enclosures are designed to protect the components, with whatever concessions necessary to allow the cooling air to flow.
Make sure there's a free path to allow the air to flow all the way through.

RE: Airflow in a (PC)-Case
It seems I am having problems to get my question across; the cube on the right is closed of and has a flush mounted bottom fan. The cube on the right has an open bottom with a "free hanging" bottom fan.
What i am trying to understand is: Is there any general benefit (more airflow) with one of these to variants?
