Chosen Solution
So I’m facing a tricky one here I got a macbook pro early 2015 ( A1502) So the fan was working at maximum speed Did the SMC and everything system related - nothing happens Installed Macs Fan Control.. Lowered the speed to the lowest.. Seems like it doesn’t have an effect at all So, I decided to open the laptop and check what’s going on Found out that the mac was previously repaired And who ever did made a power shortcut through the motherboard ( i don’t know exactly how to explain it so I’ve uploaded a picture)
So I’ve replaced the fan hoping that it will fix this problem But after booting the fan is not working at all Did the smc again, nothing happens I just want to know either the problem is in the fan pin (so i can order a new one) or the logic board itself. Any help would be appreciated Thanks
From the looks of the pictured part it seems whoever did the job tried to “save” on the fan cost of replacement (maybe the flat cable to the logic board damaged ?) by jumpering fan straight to the board. Considering the cost of that Mac and the one of a new fan seems pretty silly to me, but however..I’d try a new fan undoubtedly. Heaven knows what else you’ll find inside after seeing such a “creative” repair.
