I'm sure these are just silly little concerns, but i might as well get some other opinions anyways. The computer in my sig I have 2 concerns about #1 the black plastic the hinge piece, the plastic creeks sometimes. when i run my finger across the top of it (the part under the macbook pro writing) it makes a noise, like the plastic is bending or has an bubble in it or something. is that normal, or is there a chance it will break? #2 how hot can the CPU get? my fans do not move on their own very much, my cpu was at 94 c and i finally saw the fans at 2400. thanks everyone!
