[No-Clean]

Board looks clean.

CPU gets super hot as soon as you log in and the Mac freezes often, the main problem is that the image comes up with lines and weird colors that sometimes change in color or direction much like a GPU dying.

Is this thing done?

If CPU also overheats, should be sign of bad CPU.
Be sure the heatpipe is good.
Test cooling CPU with an external fan and see if stays more time alive.

Also test external monitor, to discard internal LCD issue...

Looks like dead CPU... farewell
