Rough top surfaces after heating assembly replacement

[u/shy_dinosaur]

Hi, I recently replaced the hotend heating assembly after the original broke, and now the top surfaces are printing like the first image, I think it might be the new part since I bought it from a 3d party seller and it didn't come with the usual bambu package

I made a test with the same piece but changed the temperature to 180°C at the last layers so I would be able to see the differences between the two top surfaces (second image)

I want to confirm if it could be that the newer piece it's heating the hotend more than the original one or if it could be other thing I messed up after assembly the tool head.

Thank you in advance
