#I should probably fix it right?

It's great that you're taking action to fix your broken fan! It's common for 3D printed replacement parts to have slightly different properties than the original, which can affect its performance. Here are a few things you can try to troubleshoot the issue:
-
Check the design: Make sure the replacement part matches the original design in terms of dimensions, curvature, and thickness. Any deviations may cause increased friction.
-
Check for smoothness: Inspect the printed part for any rough or uneven areas. Sanding or filing down any imperfections can help reduce friction and improve the fan's efficiency.
-
Lubrication: Apply a small amount of lightweight lubricant, such as silicone oil, to the moving parts of the fan. This can help reduce friction and make it easier to spin.
-
Inspect the bearings: If your fan has bearings, examine them closely for any damage or excessive wear. If necessary, you may need to replace them to restore the fan's performance.
It's important to no...
Looks like the heatbreak cooling? Yeah, it would probably like being fixed
print a new fan
Buy a new fan please 
Or you can see what happens when your heatbreak and extruder gets too warm. But there's no way you're getting reasonable airflow out of a printed blade assembly.
well I don't much understand how fans work but it prints good as I said, I thought to try printing the two pieces I broke and gluing it in
maybe it will do the job
heatbreak is the thing cooling the print?
Heatbreak is the part that cools the upper part of the hotend where filament is supposed to be kept cool.
If it's gets too warm from the heat coming up from the block the filament melts where it shouldn't and jams.
because I think the of this fan purpose is to cool the print
Dependingon the ambient temperatures you might be fine, but with longer prints and higher nozzle temps you can end up having filament jam in the extruder or if the extruder gets too warm filament wrap around the gears.
yes exactly
That fan blows through the back of the extruder assembly to cool the fins on the back of the toolhead.
This cools both the extruder and the heatbreak.
That one cools the print.
The one with the duct pointing towards the nozzle.
oh my bad
No worries 😛 And honestly it might be fine for a bit.
But eventually the vibrations will kill that fan, and you don't want to deal with the hell that is a jam on those units.
Source: have four Sovols, one extruder experienced exactly that situation.
so those units stuff need good cooling?
four🤯
I find that if you're printing PLA yes, they do like to have adequate cooling.
Otherwise the PLA gets nice and soft and wraps itself around the extruder gears like TPU does.
So what do you say I try printing the two pieces that broke and gluing it in?
No, I'm saying you should replace the fan.
