Not sure what the difference in width would matter if the power draw/requirement are the same? I would try putting standard power (from a desktop PSU) to both and make sure they function correctly outside of the laptop (a molex connector can be configured for 5v/7v/12v as seen here: 5v/7v/12v. You would just have to look online for the wire layout and find out which lead is + & -. You could also test your failed fan and see if it works outside of the laptop. It could be the mobo power connector that failed and not the fan. Did the original fan seize? can you turn it freely with your finger? If you can, that would lead me to believe its not getting any power.
I know some laptops these days now have 12v fans instead of 5v, but those are some of the newer models (such as the G703). Not sure about G750JS.

I used a old USB cable and connected to the fans, and both worked... Apparently the red and black wires are working properly. Does it have any relation with the blue and yellow? I forgot to mention, but my old CPU fan is still working, I connected to the GPU plug and was fine. I'm out of ideas now haha. Could it be just an incompatibility at all?
Thanks for your help.
