[QUOTE="pigoo3, post: 1840894, member: 56379"] First of all we need to keep things in perspective. This is a 2012 MacBook Pro (7-8 years old)...if it's a 13" model...and if it was working 100%...it may only be worth about $250-$300. Unfortunately it is not working 100%...which means it's probably worth significantly less than $250-$300. Thus we want to be VERY careful not to spend too much money getting it repaired...since if you took the current value of the computer + the estimated repair cost funds...these funds together could purchase a newer computer (used)...that is working 100%.:) As far as the thermal paste question. As you may or may not know...the thermal paste (in many situations) is a "connection or link" between a computers CPU or GPU and a heat sink. Heat sink is necessary to dissipate the heat generated by the CPU or GPU during use. When thermal paste gets old...it dry's out & shrinks (and maybe falls out)...and the "connection" between the CPU or GPU and the associated heat sink is lost. This will cause the computer to operate at a higher temperature...and if the temperature gets high enough...the computer will start acting "funky" or shut off. Thus one thing I would look for is unusually high fan speeds. If there is a thermal paste issue...the computer will be trying to cool itself off by increasing the fan speeds. If you're not experiencing high fan speeds (or a loud fan/fans)...then the thermal paste theory may not be the correct issue. HTH, - Nick [/QUOTE]
