[G73JH] Graphics Card Overheats almost immediately after startup

So I got the laptop used and it worked perfectly for about 2-3 weeks, but suddenly today I've run into this issue where immediately the Graphics, and just the Graphics will slowly increase in temperature from around 60c to something like 113c before it simply shuts itself off. I mean, I understand that at a certain point if I want to do anything intensive I'll need to paste it or blow air, but for it to overheat without any activity just seems crazy.

 

Sounds like one of the heatpipes may have a fault with that much variance or the mounting has failed.

 

Well, I tried spraying compressed air in the fans but it didn't seem to really do anything, although now it "Functionally" idles at about 96c, I can browse the web and stuff but that's it. Feeling the back, air seems to only come out of the left side vent, while the right seems to be doing nothing?

 

That sounds like the GPU fan is broken. You will need to replace it for continued function.

 

You need to have your GPU repasted,

 

Or there is a carpet of dust blocking the vent. Physically check to see if the fans are spinning and if there are obstructions.

 

Well, good news and bad news. Good news is, I took it apart, turned out something was physically obstructing the fan from spinning and by blowing air into it it was all good/been working for about a month. Bad news is it's stopped working again, I think the same issue, is there any way to access the fans or get them spinning again without having to mostly disassemble the laptop?

 

Not really i'm afraid, Asus changed the design and removed the little access covers.

 

Good news is that it is always easier taking apart the second time. Usually faster and less chance of breaking things. What was the "something" blocking the fan? Are you sure it isn't just a faulty fan? If you take it apart down to the fans and heatsinks, repaste it if you didn't do last time. A replacement fan shouldn't cost much, and might be worth doing at the time you take apart.

After a careful disassembly, clean, and repaste, you'd expect it to run happily for at least a year.

You might want to see if the fan needs oil or needs replacing.

 

I would take out the GPU fan and test it with an switchin power supply on its rated voltage .. ( 5V I guess)
..when it is working outside it may be a faulty motherboard fan control chip..

 

or bad heat pipe, if it got enough enoughtimes perhaps it caused an issue with heat sink.

PRO TIP: instead of removing the screws form the screw holes after screwing them, put tape over the hole to hold the screw while separate the laptop/remove covers. I can do a total tear down desolder and solder a DC jack and repaste and fix other issues in an hour-1 and half hours, sometimes quicker. rare do i have to memorize screws or screw locations.

EDIT: just be sure your not reusing the old thermal paste are you?

 

What is getting into the fan?

(the temps are going up because his fan was not spinning).
