What are the current recommendations for stand-offs between a few boards?
With only two micro server boards, I will probably use use two power supplies. How much space should I leave to insure adequate cooling, i.e. what length on the standoffs. I have them in front of a full size fan, running at 43 degrees C right now.
If I don't wire them together, will I be alright with conductive standoffs? Nylon? Aluminum? Brass?
Thanks for any advice you can give.
