Uhh, about to apply AS5 but....

I used Alcohol to remove the melted OEM thermal compound in the middle. But there is some more stuff on the left side... Do I touch the or remove the OEM thermal compound or leave it on?

If you don't know what I mean its the stuff in the pic below where the stuff is not on the CPU but on the thing further up.

(Ugg sorry for reusing the pic)

 

leave the pad on the chipset. Just clean the heat pipe and the cpu itself........

 

Yes, leave the thermal pad.

 

Thanks , After applying AS5 for the 1st time...
CPU 43C -> 39C....(not much change)
I took apart and redid the Arctic Silver 5 (this time with much less thing layer)
and now....CPU is down to an amazing 26C.....

 

I removed the thermal pad (not knowing i should've left it on) and applied AS5 to the northbridge, is this bad?

 

As long as theres no gap. Thermal pads for the chipset is usually 1mm+ thick, if your one is then i dont think the AS5 is touching the top end which can be bad.

 

Is there a reason not the apply AS5 to the Chipset and GPU?

 

GPU yes but unnecessary for the chipset.

Do you also have a thermal pad for your GPU? What is your GPU?

 

So is cooling necessary for the chipset really? Why did you instruct to not touch the factory stuff on the chipset?

It's a 7805u, 9800 GTS Nvidia.

 

If the Northbridge is not properly cooled either it will shutdown your laptop. When I was a newbie many years ago, I removed the thermal pad on the northbridge and replaced it with Artic5 compound, but did not realize that the compound could not close or bridge the 1mm gap, so about 30 seconds into botting into Windows my laptop would shutdown. Once I put the Thermal pad back on it worked fine. I even put in a thin layer of Artic5 on the thermal pad and it seemed to have helped some. I hope this helps. God Bless
