Cooling fans

[katchanielsen 0]

Hi, I'm currently working with a Ultimaker s3, and I don't get satisfying results and i suspect it is because of one or both of the cooling fans.
One side of the print just doesn't look right, like it have had too much heat - and yes i am using the default settings from cura. 
This might be a stupid question, but is there a way to check if the cooling fans work as they should?
If yes, how!?

Hi, 

 

Could you share a picture of your prints so our experts can also have a look at it?

If one of the fans is not working I believe this should most likely be due to a pinched cable, can you see any damage? Otherwise, I would imagine you should be able to feel the difference between both fans with your hand.

It is not so easy, because it is hard so see if they are running. But I was able to check it with a flashlight from the top. 

It is easier to check it first when the printer is idle, to see how it looks like when the fan is not running and then again when the fans are on. Then you see that there is a difference.
