Ender 3 V3 Se hotend 2510 fan not working

Hello all,

I made a quick search but I couldn’t find a similar issue on the forum.

I just bought my first 3D printer last week (Ender 3 v3 se). I never got to a point where I could print parts unfortunately. I found out that the hotend fan was not working at all, even when the nozzle temperature is 220 Celsius. I exchanged the sockets of hotend fan and part fan and part fan worked OK when nozzle temperature was high, so I assumed my 2510 24V fan was faulty. I bought two more of the same fan, and both of them didn’t work as well:/ Then I installed spare 4010 24V fan to hotend, and it started working. So it seems like 2510 fans are not working, but 4010s somehow do. Does anybody have any idea why would it be like that?
