A Venturi desk fan ultra quiet (if you use the good fan). I used the following things : - https://www.amazon.fr/Noctua-NF-S12A-ventilateur-bo%C3%AEtier-120/dp/B00BG20KCY - https://fr.aliexpress.com/item/2A-DC-DC-Step-up-Boost-Converter-R-glable-Booster-DC-DC-Step-Up-Module-Adaptateur/32907799796.html - https://fr.aliexpress.com/item/TOPK-LED-Magnetic-USB-Cable-For-iPhone-6-7-8-Plus-5s-SE-iPad-Air-Charger/32827864878.html - https://fr.aliexpress.com/item/5PCS-LOT-Black-Push-Button-Mini-Switch-6A-10A-110V-250V-KCD1-101-2Pin-Snap-in/32691789699.html - Bolts M3*12 The switch is optional. USB magnetic cable is enough to turn on/off the fan. With the set up boost voltage (12v - 18v), you can choose between the silence and the ventilation power. For my case, i choiced the silence. The set up boost module is only stuck (no screw, no glue)
