Laptop has been running hot and shutting off a lot lately. The GPU would get to 100C while playing Anna on lowest settings, for example. Red Faction would also overheat after some time, but would run without a shutdown if I pointed my 6″ desk fan at it.
I removed the back panel screws then popped it off with a precision flat-blade screwdriver. The panel lifts towards you, then pulls slightly back, as there are little tabs near the front of the laptop.
Removed the four screws from the video card. Be careful with it because it is held in underneath by the thermal paste on the GPU, and three pieces of thermal tape. It also lifts up at a slight angle at the connections, just like when removing/inserting RAM. You can see how the lettering on the GPU through the compound! Very thin. I put Arctic Silver 5 on the GPU and also on each chip instead of the tape. I cleaned off the GPU in the second picture, and eventually the edges.
I had to bend the heat pipe upwards to get under the CPU heatsink. There might have been another way but it looked like that would require more disassembling that I didn’t feel like doing.
After cleaning all the contacts, it was time… Sorry that I didn’t take have more pictures of the application. Actually I probably should have done a video, but I just dove into it and wanted it done to play games!
SpeedFan comparison. From boot to idle, then opening Facebook and scrolling up and down a bunch. Blue and white are CPU, green is GPU, red is just.. Temp
