The Newb's Guide to Repasting Your G73

[smitty870]

Thank you for this guide! My average temps across the GPU board per HWinfo32 and GPU-Z were 58C to 65C. Now after a repaste my average are now 46C to 53C. It also seems after a repaste my CPU temps have dropped and average of 8 to 9 degrees C. I did forget to tape the fan and radiators, but I am not going to go and take it all apart again.

Congrats on the new temps. I'm glad it helped.

Awww.. makes me so jealous I'm dying to have a repaste T_T

By the way, would you mind telling us what paste you have used on your CPU and GPU?

I'll be posting here too my before and after, after I repaste mine.

You've repasted your CPU too? What happened to the warranty sticker?

Oh I used ICD7 and maintained furmark temp of 84C for 1 hour with a GPU fan speed reported at aprox 45,000 RPMs based on hwinfo32. I did not touch the CPU because of the sticker and voiding my warranty. I think the extra heat generated by the video card before the repaste was causing the CPU to appear to heat up. During the 1 hour testing period the CPU never reported higher temps then 60C while the GPU never went about 84C.

Tol, We used IC Diamond. It works perfectly. Today im going to meet scampupy. Another filipino member of this fourm. He's gonna buy my last tube of ICD7. If you want, the three of us can meet. And you can ask him to put some paste in your gpu. You could just pay him around 200pesos. And you guys can repaste together. I'll PM you my number.

Things to consider-

-All temp comparisons are meaningless unless we know what the ambient temp was when you tested. What you are really trying to measure is difference between GPU temp and ambient temp.
-Idle temps are useless unless we know what "idle" means to you, the ambient temp and how long it was idle. Temp needs to stabilize.
-Furmark runs hotter in a window than fullscreen, and be sure that vsync is not forced in CCC.
-The newest video and/or system BIOS may have a tweaked fan profile to limit max temp via higher fan speeds.
-All GPUs have slightly different power output, meaning temps will vary between them. Not every die is identical. There are outliers.
-The difference between the best pastes and worst is not that significant. It matters more how you apply the paste (really that you just have complete coverage and no air bubbles) and that you just do have some sort of TIM. The G73s have a slight problem with the RAM thermal pads preventing good GPU/heatsink mating because they are ever slightly too thick and the mounting screw-springs too weak.

I will rerun the tests, I know ambient temp was right around 20C in the area of the laptop and furmark was windowed. I did not take in consideration of the rest. Thank you for info.

Just finished my repaste with great help from this thread. The good news is that my g73jh went from 110+ furmark in 3 minutes to 85 after 5 minutes of furmark (with a few minutes of gentle polishing of heatsink before ic diamond). Bad news is broke the socket for the speaker right of the motherboard I reattached it carefully and still have use of one of my speakers.

[Chastity]

I guess you will be using headphones more often, or external speakers.

[peepingyoda]

Yeah, I game with headphones anyway.
