This is the 24V PSU I am using and its fan is PWM controlled. I don’t think the product description says one way or the other.

Hey all,

I built a Chinese kit with some quite nice components, but the included power supply is §$%&.Its fan is waaaay too loud and never stops running.
I saw on some other printers that the fan only turns on when necessary.

So… how do I find a power supply that has this feature? On aliexpress I did not find anything to help me filter…

Thanks in advance!

which voltage 12 or 24v?

i have a 24v which regulates the fan. (but it is not available by the seller)

maybe: https://de.aliexpress.com/item/NTC-3950-Thermistor-PWM-Temperature-Probe-Speed-Controller-Board-Control-Module-Buzzer-DC-12V-5A-CPU/32843879982.html?spm=a2g0x.search0104.3.9.5ea44640G8LeEx&ws_ab_test=searchweb0_0,searchweb201602_3_10320_10152_10321_10151_10065_10344_10068_10342_10547_10343_10322_10340_10548_10341_10696_10084_10083_10618_10304_10307_10820_10821_10302_10846_10843_10059_100031_10319_445_10103_524_10624_10623_10622_10621_10620,searchweb201603_25,ppcSwitch_5&algo_expid=fd5665dd-2368-4e67-a749-6bd7968f9ce6-1&algo_pvid=fd5665dd-2368-4e67-a749-6bd7968f9ce6&transAbTest=ae803_2&priceBeautifyAB=0

would help / find a component which gets hot on the power supply and but the temparature sensor on it.

I’d like to avoid hacking the PSU :smiley: but if it’s not possible to order what I want, then I’ll probably do it
