Issue with replacing 24v fan with 12v fan using buck converter
I really want to reduce the noise from the hot end fan so I bought a noctua fan and a buck converter from amazon. I was following a couple of guides for how to do this but none of them mention (and I didn't think about) the fact that buck converters not only reduce the voltage (good) but also increase the current by a corresponding amount. This will take the current over the specified max current and blow the fan. So, do I need to find a buck converter with a limited/adjustable output current as well as adjustable voltage? Or am I doing something wrong?

You can still use a single buck converter to run the fans individually. To this end, simply feed the input of the buck converter with 24V.

I installed my buck converters, after setting them up on a 24v power supply.
Connected up the control box fans with the converters.

I then installed my new 24v PSU.
Turned the control box on and the noise was really deafening!

It sounded like my vacuum cleaner was on the table next to me.
My control box was really vibrating which exacerbated the noise.

I had set my buck converters to 12v. Could I have had 6v fans? lol
I shall strip it down again tomorrow and retest the converters.
