Side cooling fan problem

I had to take apart my extruder due to a filament jam.

I forgot which direction the side fan of the extruder was facing? Sticker side up, or sticker side down?

I have the Snapmaker original.

The Fan blows on the heatsink.
This means, it blows into the module.
Hope this helps.

If the extruder is connected, the fan will start spinning as soon as you turn the unit on. So flip it on, see which way it blows, then turn it off.

I had the same issue. I also didn’t turn the unit off while I screwed the fan on, and I broke several fan blades when the screwdriver slipped. :frowning:

Yes. Thank you very much
