The 40x20 part cooling fan in my BigBox died today and I'm surprised how hard it is to find a replacement fan. Is there a trick to using the 50 side-blowing fan E3D sells as a replacement?
Here is one I found on eBay, just search for : “24v 40x20mm blower fan” https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/121880735532
Ordered two of these, will report on quality: https://www.ebay.com/itm/24V-40mm-B...Cooling-3D-Printer-Rep-Rap-2-pin/182324018357
