Ender 3 V2 Motherboard Cover for 40x40x20mm fan

thingiverse

Super simple design I made for modification of my Ender 3 V2 with 40x40x20 fan in mind (I've used the quietest Sunon 40x40x20 24V fan with only 21dB noise level). Fan is relocated to a different position on the cover so it fits perfectly over the motherboard right over heatsinks and between connectors that otherwise collides with on original motherboard cover panel, providing extensive cooling with significantly lower noise level. Because I could fit 24V fan this way, I did not require a buck converter. Fan is fully exposed to eliminate fan whine that is caused by protective fan grills and plenty of holes around it provide good ventilation. This cover design can also be used to fit original Ender 3 V2 motherboard fan which should also be quieter because there are no grills to create intake whine noise as well as increased distance from motherboard components decreasing fan exhaust whine. Cover is designed to be fitted using all the original screws with exception of the fan itself which requires new screws due to bigger thickness and is screwed in from the outside using standard computer fan screws.
