Hotend Fan keep running non stop.
My hotend of Prusa Mk4 has cooldown to 28C room temperature but the hotend fan keep running non stop. It does not affect performance of printer just really annoy when I am working and taking nap can hear the fan noise. I also worry about the Hotend fan longevity if it keep running.

Hotend fan I mean heatsink fan. It keep running 24/7 even when printer is in idle and hotend temp show 27C room temperature.
RE:
It's interesting you mention this because I noticed over the weekend that my Mk4's hot end fan was still running despite being pretty much cooled off after finishing a job. I didn't pay attention to the specific temp, but I remember noting that it was below the ~45c cutoff where the fan has been historically turning off. I wonder if there was a change in the latest firmware.

Glad this is not hardware. I was thinking issue from LoveBoard. They probably release 6.0.4 to fix usb and this.
