Melted replacement fan

[ermhelpplz]

Hey,

 

So erm my laptop cpu fan decided to start making a grinding sound on me and i ordered a new fan it looked different to my laptop fan but had the same part number on the bag so i contiued and went ahead with replacing it, i powered on the pc and was immediatly hit with the smell of burning i powered off the laptop and discovered that the fan motor had had a brief fire and went bang...

 

After closer inspection of the fan i saw that its only a 5v 0.5a fan where as the stock fan is 12v 0.5a

 

 

So after waiting for another fan to come today which actually looked like my fan after installation and had the right power/wattage i now get no power to the fan is it possible that the first fan shorted something when it went bang?

 

I dont see any burn marks on the board but i also dont have any equipment to test for power

 

 

What could i do? 

 

The laptop make is preditor helios 300 ph317-55

Yes, it is possible that a wire, a trace, a connector or a fuse were blown when the motor overloaded.

As for testing equipment, you can find cheap multimeters in almost every hardware or electronics stores these days. (a led and a resistor can do the job too).

On the other hand, I recommend going to a tech repair because you'll probably need some work to repair or replace the faulty wires at this point.

Hope that helps.
