24v fan on 12v power supply
-
Hello,
I know its possible using 24v PSU to power 12v fans by connecting step down voltage regulator to middle pin.
However my situation is other way around. I have 12v PSU and I have to use 24v fan.
Is connection the same as in first case (can I connect 24v Input to middle pin?) or its gonna fry my board?
Also I will use separate 24v power supply instead step up regulator.Thanks

As mentioned before I know how to wire 12v fans with 24v power supply. In my case its 24v FAN and 12v Power supply.

if you use a step up converter that should work.
you can also try just running your 24v fans on the 12v supply. they will run slower but also less noisy.

Apologies, I misread..
-
Do you think that separate 24v power supply will work instead of step up converter? These step up converters are unreliable and fail quite often.
I use 24v fan because its specific suction blower fan and I need it for my application. I'm not building 3d printer, its going to be xyz positioning stage.

@arkadiusz It will work but you need to connect it ground to the 12V ground, both power supplies need to have common ground.

It's possible; but buying a 12V fan is almost certainly going to cost less and be easier than any other solution.

Cool I know what to do now, thanks for help everyone.
