Noctua NH-U12P Heatpipe Tips

[FusionXP]

Why does it look like the tips of the heatpipes look like they are melted. Is this by design or a quality issue?

Here is a review of it with good close up shots.

its a normal manufacturing thing. Not as neatly done as most I have seen but /shrug.

Notice the tubes are U shaped. One end is neatly machined. then they fill the tube with magic and then seal the other end. Its this other sealed after filling end that is looking a little funky. Not an issue other than ascetics/looks.
