Hey, so I recently fixed my G5 and removed the heatsinks from the CPUs (I replaced one) and put some thermal paste on it. By the way I am not sure if there was glue or paste at one point but I just put paste on it. Now to my question: I have a replacement logic board and I saw that there are some heatsinks at the back. Do I need to remove my working logic board out of my mac and put some paste somewhere?
