80mm Fan Duct for cooling a WD Elements Enclosure

thingiverse

Simple fan duct to add an 80mm fan to the top of a Western Digital Elements enclosure. The duct is tight around the front and sides and covers the back grill down to just above the power button with a 5mm gap forcing the air to go up and across from the back and up from underneath the enclosure. ** 20th July 2021 - Added Fusion 360 file for easier modification** Some people have been asking what the point of having this is... * You could just slap a loose fan on top of your enclosure, which is what I did; however, I accidentally knocked the fan onto my desk a couple of times, and since the fan is bigger than the enclosure, I wanted to maximise it's efficiency. * Even under normal conditions when using this drive regularly, it gets up to around 45°C on a 25°C day, but with this duct attached, it never goes above 31°C. * I stress test my new external drives for 60-120 hours straight when I first buy them to see if they are prone to faults before I remove them from the enclosure and void the warranty. Doing multiple, full random read/write tests continuously in the enclosure pushes temps above 45°C which is not the typical temperature they will be running at once I remove them from the enclosure and put them in a server. Temps were 30-35°C for the entirety of the tests. Print Details: Orientate the part to print with the fan square on the bed. Use supports on build plate only as there is a 5mm rim for the fan to sit in. There are screw holes, but I find the rim is enough to keep the fan in place. This is version 2.5 in which I have added a bevel below (when printing) the rim that sits around the top of the enclosure so you know when it's sitting on the enclosure properly. I haven't printed this version but the only difference is the bevel on the inside rim which should stop the rim sagging or having loose filament from printing on air, and may avoid generating extra supports going up inside the duct; however if you see supports going up into the duct, you need to add a support blocker where the rim is. It doesn't matter if the rim has loose or sagging plastic, it won't affect anything and will still do it's job.
