We need more info then that. (brand&model or better a picture)

Every manufacterer uses their own color scheme.

 

Its not like in the movies, that if you want to defuse any bomb you cut the red wire...

I dont really know much on the fan, all I know is it has a red (+) black (-) and yellow (ground) with a blue wire I assume is for speed throttling. The fan is the internal fan that came with my laptop (Asus VivioBook 15 x512)

If it only has 3 wires chances are it the RPM sense wire, that only reports back rotating speed of the fan.

It does not controll anything.

(It needs a 4th wire that will send PWM signal to fan for speed management.)

At this point, would I need to replace the fan, or would I just need to link the broken wire together?

If the fan works, and the speed of it doesnt bother you. Its fine.

Like i said its only to report back rotation speed back to the computer.

Most likely it will run at 100% if it doenst know.
