Thermal paste for G73JH GPU

[Tim4]

Hello for everyone.
I've noticed that Asus stock GPU thermal paste degrading very fast. Since I recieved my G73JH(April). At same conditions temps got higher for 2C. So, I am considering to change Thermal paste on GPU. Problem is that, I can't find any other brand than Arctic silver here. We have AS5, AS ceramique, AS Matrix. Which one of them would you suggest?
to member of forum that changed thermal paste on their GPU: could you, please, share experince about methods of applying, Thermal paste brands and temperature drops?
I've seen forum members publishing their repasting results in different threads. I think it will be nice, if we will gather all that stuff here as reference for others.
Thanks!
Update1: For those users who are planning to redo thermal paste I found those 2 interesting liks. So, for seeker of perfect TIM application look here and here

I used IC Diamond 7 because that is what Ken Lee at GenTech uses. I had some Arctic Silver on hand but I looked up some benchmarks that showed ICD7 was clearly out performing AS5. I don't work there or sell it. That's just what I saw on the interwebz.

I used the BTO Tech video as a guide to disassemble the laptop. I found it to be excellent. I was a little confused on a couple of points. To get the keyboard out, you need to insert the screwdriver in the slots at the top of the keyboard. The trick is to tilt the handle toward yourself so that the tip is angled toward the screen. That way you get past the tab and you can pop it out. The BTO video shows the guy doing that. Also, the cables with metal connectors and black cloth like tap on them have a thick clear tape like tab that is taped down to the motherboard. You lift this tape like tab and peel it up off the motherboard and the stationary portion of the metal connector. Then it slips right out of the socket. This is best done with tweezers. The other thing I wasn't sure about was the tiny white plug in the upper right portion of the motherboard. They say to gently pry it up. It is delicate. The socket it is plugged into is white and the thing you need to remove is white. Don't pry up from the motherboard. I gently pried on the socket before I realized that is not where it comes apart. The rest of it is explained really well in the video. Heck, it's probably all explained well in the video, but those are the things that I didn't understand perfectly until I had done them myself.

Hopefully this will give you an idea what the paste is like... at least on my laptop. It is very thick and sticky. It would remind you of play-dough or plumber's putty.

Also, you can get a good look at the thermal pads. Mine looked to be made from a soft rubbery material. They looked like they were making excellent contact and the memory chips looked very clean so I left that part alone.

Thanks for sharing your experince with us, Jody. That will be extermly helpful for those who will decide to repaste their GPU. How do you apply themal paste is it "credit card" or single dot metod?

single size of pea then press heatsink down.

Jody/Chastity you showed both sides of the gpu there. Did you only paste the side with the copper metal??

the other side the clear rubbery stuff, is that the thermal pad?

IC Diamond 7 web site said to make a pea sized dot 5 to 5.5 mm in diameter and then install the heat sink so that's what I did. I cleaned the crap out of everything with alcohol and q-tips. Then I put the pea sized portion right in the middle and reinstalled the heat sink.

Thanks gyus! Very useful info.

I just got the repaste work done two hours ago.

Before repasted, the GPU idle temps (DispIO/MemIO/Shader) were 64/74/68 C (ambient 28 C), and Furmark stress test could have last for only 1 minutes before shutdown.

Having carefully ripped apart the notebook and applied the IC Diamond 7 paste, now I have idle temps of 54/60/56 C; Furmark stress test holds stable at 82/90/85 C. I'm quite pleased with it.

Congrats and welcome to the repaste club.

is there a detailed step by step guide for accessing the CPU and applying the paste?
