Hey guys, I have a dell Inspiron 570 and it originally had the athlon II, I upgraded to the AMD phenom II x 4 and finally got it in the mail yesterday. When I went to install the new heatsink the brackets are completely different and there's no way to install it. I called AMD and they said they are familiar with this issue and suggested I buy an aftermarket heatsink bc they do not make one. Thing is I'm a newb and don't even know where to start... Can someone please help me with this? I don't want to of wasted that much money for a new CPU and burn it up, bc I tryed installing the old heatsink and when I play games the CPU temp gets up to 71c! Any advice would be great, thank you guys!
