Anyone else who has the same problem?
After a print is finished, some of the fans runs for a while but the fan for the psu never stop.
It goes on and on until I turn the whole thing of…
Anyone got any solution for this?

Are you sure it is the PSU fan and not the Motherboard fan?
Yup, the same. And I assumed it was a PSU fan. I didn’t even consider a motherboard fan. Why would a motherboard fan need to run when the printer is doing nothing? Same question for a PSU fan. And, even while it’s printing, why would there even need to be a motherboard fan? Printing can’t be all that computationally intense–all it’s doing is moving a print head to coordinates specified in the G-Code, or throttling fans…oh, wait, it is for the AI?!?
Yeah. I was wondering the same sort of thing. Why the endless fan?
To cool down the processor from the heat up from your last print. A high task load (like printing) will cause it to heat up.
Mine runs for quite a while, but it eventually does shut off. If I just walk away and come back an hour later, all is quiet, so it does finally take a rest.
Keep in mind that the K1 boards have an RPi clone processor and MCU processor that need to be kept below a temp so they can run at full speed.
The PSU fan only runs while the PSU is under a load (bed & hotend heaters) and will turn off when that load is removed.
My K1C seems to be noisy all the time too. It seems much louder than it needs to be.
I have a temprature around 16 degres celsius in the room with the k1c, so it should be cooled quickly after its done.
I see that some of you have the same issue, but it turns of after a while. I have had mine up and running for 24h and it still doesnt turn of…anoying as xxx.
Understand that it goes on under load, but after it been idle for a couple of hours it should turn off.
could be…it´s a fan underneath the bed at least.
Edit: Checked now, and it is the psu fan that runs non stop.
I have 6 FDM machines from 3 manufacturers and all of them the PSU fan runs continuously. I’ll put money my on my resin printer PSU fan runs continuously too.
Strange…Doesnt run when your turn it on, so why cant it shut down after a while.
Maybe change it? or doesnt that help due to some controller thingy?
It could be the Z motor, if enabled to keep the bed position. I noticed its heating a lot regarding the actual position. Try to add some motor off in the end of print gcode
My K1C fan runs for 20 minutes or so after the print terminates, but then it stops. After that, the printer sits there silent. I can’t see where it should run for hours.
I have the issue too, makes no sense. It’s not noisy when you first turn it on, It’s been all over 2 hours since my last print and it sounds like it is blowing a gale. I am exploring ways of sending custom commands after print that shut it down after a while, or some way of using an IoT smart plug to turn off the entire printer an hour after printing, if anyone has a solution that doesn’t involve buying any more accessories I’d love to know.
Having the same issues with my new K1C which only arrived a few days ago, When I turn the printer on there is no noise/fan. After about 20 minutes the fan starts like a hurricane even though no printing has taken place and never shuts off. I’ve waited 6hrs with it at idle and no change.
It makes no sense that the PSU fan should be running constantly. If I cut power to the printer and turn it back on again immediately the PSU fan goes back to being silent for 20 or so minutes so its not turning on for needed cooling or else the moment the printer started up again the sensors would tell the printer to start the PSU fan again. Very infuriating.
Has there ever been a response from Creality on this issue?
