Hotend Fan question
Hi all. I've recently gotten an SV08 to replace an SV06+. Everything is stock/out of the box except I added a BTT HDMI screen. What I've noticed is that after a print completes and the hotend cools down (to 45C because that's what's in the config), the hotend fan turns off. Then, after a period of time (not sure exactly how long), the hotend fan turns back on and continues to run. In Mainsail, the hotend fan shows ~17000 RPM, and 0% (which to me indicates that Klipper isn't commanding it on). Is this normal? Or is something in the config not quite right?
EDIT to add more clarification:
Additional detail: Mainsail shows extruder target 0°C, heater off, current temp around 29°C when the fan is running. It does turn off normally after cooldown, then comes back on later by itself. So it’s not just “fan stays on while hot.”
