I was wondering the way to put the Raspi 4 onto my telescope, Noctua is a good one to avoid vibrations ... Have any people resolved vibrations to the telescope with fan ?

If you look at the link in my last post, the case I designed allows for a Noctua fan on vibration isolation pegs. It can mount on my telescopes with a standard synta/finderscope mount. I don’t notice any vibrations with the fan running at 5V.
