    @ u6b36ef thanks for answer...

    this is the Copper Pad Shim that i use on my card:
    10pcs Copper Hearsinks&Cooling Copper Pad Shim laptop CPU Size:15mm*15mm*0.5mm | eBay
    (are you sure can i put biger Copper Pad Shim from this?)
    and i put Copper Pad Shim like can you see in this photo: http://i49.tinypic.com/208xkyv.jpg
    i use paste on both sides of the shim.
    please tell me your opinion.

    i am sorry for bad english...

    @ Avora said me:
    " I just suggest that the GPU needs lower voltage to reduce the temperature. However on these machines the heatsink is all one so the CPU can be undervolted as well to further help the cooling of the GPU. In my 5920g I fitted a t8100 CPU which reduced the heat. And then fitted a 4650 with a copper shim. These created a faster and yet cooler system. Just my solution, I know that it works if its done correctly. "

    what about this? about undervolting of GPU (.the temp o my CPU is 63 C max in idle mode, can i try undervolting of CPU ?)

    That looks fine.
    I had 15mmx11mm, and I replaced it with 15mmx15mm, and it took a degree or two off straight away. (I cut these pieces from a salvaged laptop heatsink.) **It's just that the more shim you have touching the heatsink, the cooler it can get.**

    In this 5920 for example there is a black plastic squarey shaped thing which sits on the heatsink. I guess it's just a guide for placing thermal pads. I think some people remove them, but anyway that has a size that would limit shim size, to about 17mmx17mm. It might be advantageous temperature related to remove the plasicky thing, and use a 20mmx20mm shim. Can't say, as I never tried it, but the theory is good.

    By the way, is that a picture of your 9600M GT?

    Hi guys
    I just got my hd 4670 mxm2 from MSI. I installed it in my Acer 6935G but it doesn't boot, the screen doesnt turn on. I can hear fans, and the gpu is getting hot.
    Does it mean, I cannot use this gpu or is there a way to make it work?

    @botexnet

    Is it DDR 2 or 3 card?
    Can you post a GPU-Z screenshot?

    You can mark HD 4670 GDDR3 512MB from MSI working on Acer 6935G as well. I had to reset my bios after 9600m gt failure. Temps are 43-65 celsius. I used Zalman zm-stg2 thermal paste and Phobya XT heatpads.
