Originally designed by Logan on the PrintNC Discord server. This one’s just remade in Solidworks and has a slightly different blade profile like a Noctua fan.
A fan that attaches to the collet on a CNC machine. This model still needs more testing but so far it handles spinning at 24k rpm.
Warning I would only use one of these things with a full enclosure. No telling what damage it’ll do when it eventually explodes at high speed.
See a video of it spinning at 24k rpm:
