Recently I bought some of the vents that Qiang fu kiwi had for sale. Apparently they can be bolted directly to a 60mm fan. I had a look on eBay and aliexpress and there doesn't seem to be any dc5v 60mm fans available. 90% of my display is dc12v so no problem there but I have a high pixel count strip that I'm using for a matrix that is 5v Is there a dc5v fan available that can bolt to these covers What are my options if there is not and I have a dc12v fan in a dc5v enclosure????
