Starting a month or so ago, my 15" mid-2012 MBP starting making loud whirring noises and I suspected it to be the HDD and made a backup for everything just in case it failed. I decided to take a look for myself inside the Mac and turns out it is one of the fans (the left one) that's making these loud noises. The right one is alright. I was thinking of running the MBP on one fan, the right one, for now till I get a replacement for the other. However, I probably put in too much force and popped off the clip using which the fan is attached to the board. I have no experience with soldering stuff onto things (which is what I think you have to do). So I don't know what to do. Should I run the Mac on the noisy fan for now till I get a replacement? I live in a rather remote region, and it's hard to get customer service for Apple products.
