Raspberry Pi 92mm case fan stand

thingiverse

I use a Pi 4 as my NAS and wanted it to stay cool without making any noise. The "regular" Pi cases with those 30mm fans are still to loud for my special use/placement case. I found the VESA mount made by BusinessUser and just removed a few bits of the part to save PLA and print time, it will be only used standing anyway, so no need for the mounting holes. I attached a 5€ Arctic F9 92mm case fan ( https://tinyurl.com/y6lr8r4j ) and modified the fan connector so that it can run from the 5V and ground pins on the PIs GPIO (remove the tacho cable and switch places of the other two). The fan only needs a bit over 2V to start spinning and does not use a lot of energy so it shouldnt be a problem to run it from the pins over long times. Its barely audible running on 5V and cools the PI down quiet a bit, so that overheating shouldnt be a problem anymore. The Pi is attached with M3 screws and the fan can be attached with the regular fan screws that come with it. I should have shortened the fan holder s a bit too, but I didnt think about that before printing and didnt want to waste a total usable part just to save a centimeter in height. But you might consider that before printing it yourself.
