So I've been thinking of upgrading my UMO+ cooling fan setup. My current machine is unmodified and only blows air from one direction, leaving the other side with something to be desired. I have what I feel to be a solid solution to this problem that doesn't have to do with modelling and printing a complex, melt-prone duct. I've been browsing Amazon and found these centrifugal PC fans that allow me to mount them in a very convenient way. I'll link them here: https://www.amazon.com/gp/product/B07L2YH79Y/ref=ox_sc_act_image_1?smid=A2QQQKMKGVNA5E&th=1 I plan to use two of them in my theoretical setup: Conveniently, they're available in both 12V and 24V variants. As I'm aware, the UMO+ fan output voltage is 24V. Here's my ultimate question: Should I wire 2 24V fans in parallel or 2 12V fans in series? Or should I even use these fans at all; What fans would be ideal for this application? I've read it's really easy to fry the board if done incorrectly, so I want to know how to not do that. Thanks 😃
