It was long ago but I was this dumbass. I kept reading online people said a fan was optional and didn’t understand they meant a case fan not a CPU fan so I built everything and couldnt figure out why it wouldn’t turn on. Realized fairly quickly and bought one and everything worked after that
It might be sufficient if the case airflow is good. Not sure if you could avoid any heat throttling that way, but I’d guess it wouldn’t need to shut down because of heat.
Depends mostly on the CPU “TDP” (even tho nowadays the TDP is not an actual power limit) and size of heatsink, check out Streacom passive cases for example.
But the essential part in a pc is the heatsink, before the cpu fan (or any fan).
You can stick wires with mains voltage into any two pins of any motherboard connector but there’s a reason they’re not shaped like an AC receptacle 💥. Unless it’s a ZX Spectrum, that cheap thing used the most basic connector (3.5mm jack) for everything: cassette I/O, video output and, unregulated 9V DC power input from the transformer brick, and people would often fry it.
One thing I noticed and appreciated when I first tinkered with my computer was the whole “There’s only one place this can go” for the more critical cables. I did mange to mess up my fans, but that wasn’t a big deal.

Technically, a CPU fan is also optional but you need to provide some other cooling (water pump?) or accept massive throttling.
noctua have a passive cpu cooler, NH-P1 https://www.noctua.at/en/products/nh-p1
But that will not work unless in a wind tunnel of some sort

There’s always natural convection - on a 25W CPU you should be fine
I don’t get the point. You still need an exhaust fan for the case. Maybe in an open air setup I guess?

I didn’t realise that I need to buy a power supply. I had a fully assembled computer and was asking myself how I can plug the thing in.
Also just bought a psu after and it still works like a charm to this day.
