Ultimaker 2+ background fan makes a lot of noise

[ubtje 1]

Hello,

 

I need your support. I got an older ultimaker 2+ (2300 print hours) and every time I turn it on the Hot end cooling fan (the horizontal fan at the back) immediately start turning (this is also not normal right) and making a hell of a noise. While normal ultimaker 2+ are quiet during start-up.

 

What could be the problem and should I do to fix this? It is not that the screws are lose or so.

Will a new fan fix this problem and follow this manual: https://ultimaker.com/en/resources/50657-replace-the-hot-end-cooling-fan

 

What type of fan should i replace it with then? Is this the correct fan? https://www.cards3dprinting.com/model-cooling-fan-12vdc-01a-1313.html

 

 

Couldn't find much about this on your forum.

 

Thnx for helping!

The middle fan is responsible to cool the hotend and turns on automatically. Depending on your mainboard in the UM2, the fan starts immediately when you power on the printer or when the nozzle has a temperature higher than 40°C.

 

So if the fan makes too much noise, then a new one can help and I would buy an original one from an Ultimaker reseller.

 

If you have an older mainboard installed then the fan starts after power on and there is no workaround for that, except to change the main board to a newer version.

Thnx for your reaction Smithy. Just took a good look at the fan and 5 blades are torn off. I think this caused the problem!
