    Since I replaced the top case on my MacBook, the fans have been running pretty darn high. The CPU reports around 61 degrees celsius. I was careful not to touch anything else except what I was working on.

    Of course I looked around and stuff. The inside of the computer is almost as beautiful as the outside. Could it be possible that I touched the heatsink and slightly ruptured the cooling grease?

    The cooling grease is more like cooling cement. It is rarely applied well.

    I'd try cleaning the bottom of the heatsink and the CPU/GPU with a toothbrush, then q-tips using 91% isopropyl alcohol until there is nothing left on the q-tip when you wipe the heatsink/chip. I rarely use the toothbrush, but with the excess that gets put on the macbooks, it's a standard step.
