My fan for my ultimaker original + is not spinning fast enough and is not cooling down the print and it is warping.

This is really messing up my prints and I would love some ideas to help me fix this. Thanks.

    Is the fan set to 255 on the ulticontroller? (you can play with fan speeds while printing). not 100. 255. That's all I can think of. Otherwise maybe defective fan? I guess the PCB could be partly broken but usually it fails all off or full on.

    True @gr5 but if it's the transistor of the mainboard fan pwm there's always a chance that just works but 'weird'.

    Check the fan control con the Ulticontroller/Control/Temperature/Fan and set it to 255 like gr5 said. Does it spin fully?

    If not,

    Change fan speed to 1. Does it spin faster at 10 than at 255? (255=100%)

    So please check how fast it works at 255 and at 1. If it moves faster at 255 than at 10 then there's nothing wrong with it, also make a video of what's happening, that always helps.

    Maybe the fan is connected to the wrong connector (5v instead of 12v). Is there any fan control at all? Does the fan start spinning as soon as you power up?

    5v connector plug it's different and doesn't fit the molex of the 24v fans.

    Remember it's the same board you have on um2.

    But indeed that's the question, does it change the speed at all??

    I would suggest that please make a video, sometimes it's just easier because you might be calling something with a name and we understand other thing etcetc.

    Good point. There are 2 fans so...

    Maybe a video showing with fan set to 0 and 255 would help. It sure sounds like something is broken - but I can't decide if it's the fan or the PCB or if you have completely confused us.
