Can someone please help me with installing an AMD CPU Fan Bracket Base for AM3 socket? i had to buy another one because my old one, the MIDDLE lever in this picture(http://thumbs3.ebaystatic.com/d/l225/m/mm_SxHVelceTm2oSH5ld1Sg.jpg) where it attaches onto broke off so now there's nothing to hold the heatsink in place. so far i believe the back plate isn't broken. i'm amusing it has one because this one on ebay that i bought (https://images-na.ssl-images-amazon.com/images/I/41Ewoq3fKvL._SX300_.jpg) is coming with a back plate as well. can i just install the new FRONT bracket (in the first picture without taking off the motherboard) and leave the back plate that's already on. this is the first time i had to do something like this so i'm not too for sure on what to do.
