You need minimum 250mA @ 24v for fan.
For Arduino the power supply ratings seems alright. But be careful with those modules.
I would suggest this modules:
5v supply: https://www.aliexpress.com/item/32869518469.html
24v supply:(select 24v while buying)
You can use a laptop power supply, But if the voltage is less than 24 V , you will not be able to achieve full speed of the fan.
You can use a boost converter module to boost the laptop power supply voltage to 24 V.
I have added the schematic image for power supply. Please check the Schematics part.
