04/22/2023, 7:36 PMDear all,
I want to use the following case with my Turing Pi 2: https://www.myelectronics.nl/us/desktop-mini-itx-case.html
The case can accomodate a 80mm fan, in front and I'd like some suggestion for the fan: do you suggest to use it with air flow from outside to inside or from iside to outside?

If you set it the other way around the fan might such air from all around, not necessarily from around the nodes
Also, make sure to have a way to control fan speed. You can use, for example Noctua NA-FC1 or, so-called "low noise" cables

Any suggestion for the best RPM to choose?
Thank you
