Fan replacement spinning question
I just replaced my left and right fans on my Macbook Pro 15" A1211. when I connected the right fan cable, it did not seem like it could connect well, and kept coming off. I finally got it to stay, but now I suspect that it may not be connected cause I don't hear the fan going. Is there a way I can check to see if the fan is spinning? Can I open the computer back up and connect the power to see it actually spin? Is that safe? Is there another way to check?
