4pin molex

to the outlet?

I want to learn how to make one of those peltier thingies and a heatsink fan is needed.

it only goes one way, you can not miss the socket.

it requires 12 V , otherwise you will fry it like a tan chicken.

for that , you will need a converter that goes to your power plug socket 220V and transforms the current from 220V to 12 V
you will need two of them(convertors) by the way.

i'm using this to make a peltier cooler. It will not go to a motherboard but yes it's a cooler for the intel microchip.
I need an adapter to get this converted into 12v but i don't know the name of that adapter.

They don't seem to make male connectors for what you're looking for. Potentially you could go for a 4 pin male, maybe a floppy connector but those only come in female cuz the male side is on the floppy drive, to 4 pin molex and go from there. Why not just leave it on your old motherboard and run power through it with a computer power supply?

The motherboard is already fried. It's from an old computer, i figured why not recycle the heatsink fan?
i suck at electronics lol.

Heatsink fans are not meant to be transferred to normal electronics, like being plugged into a wall socket. I tried to google a solution for you, but you'll have to continue searching for converters like I suggested. Sorry dude. You could learn how to cut the wires and splice it or something...

I've seen those heatsink fans at work. Those tutorials however didn't show how to connect the wires. I think they assumed that those who'll make a peltier cooler has a background in electronics. I'm a freakin noob man :lol:

Cutting the wires? I don't have one of those devices that binds the wires together.. Maybe i should stick to the icepack method
