Broken Extruder Fan

So I somehow broke my left extruder fan on my Flashforge Creator Pro . No idea how it broke so easily but the end of the filament got caught in the fan while I was loading for like two seconds and this was enough to break off two fan blades. Now when the fan operates it makes a loud buzzing sound and I'm not sure if it would cool as well. Is it hard to replace the fan?

I'm a novice to hardware and electronics. I've done some light soldering/ putting stuff together but not much. I hope it's easy cause this really sucks. I've been doing hours of printing and really getting the hang of 3D printing and now this happened :(. I emailed Tang and I'm sure he will give me instructions as he did before when I had to do repairs in the past, but I'd appreciate any suggestions on here as well. I tried Googling around but couldn't find a step by step guide for a novice like me.
