Hey, im having a bit problem i have a working old dell laptop a fairly good one even having a 2nd gen i5 processor .So my problem is i got an fan error on dell diagnostic tool (fan not working ecen in high temp) so can i just attach a 4 pin 40mm fan (12v same )on the top side of laptop blower fan ? (Doesn't care about the looks) My laptop blower part is current out of stock
