    Hi guys, my sisters Asus g50 fan died and just replaced it. I also reapplyed thermal paste (ICD7) and thermal pads (akasa). However I'm still getting very high idle temps. I cleaned the cooling system and everything!

    Specs
    CPU: Intel Core 2 Duo T5750 @ 2.00 GHz
    GPU: nVidia 9700m GT 512 MB

    Idle
    CPU: ~67
    GPU: ~71

    Max (3D Mark Vantage)
    CPU: 72 max
    GPU: 85 max

    I was comparing these the my other g50v
    CPU: Intel Core 2 Duo P8700 @ 2.53 GHz
    GPU: nVidia 9800m GS 512 MB

    Idle
    CPU: ~55
    GPU: ~67

    Everything is seated correctly and tightly?

    Yeah, I believe everything is seated correctly. I reapplyed the paste twice, ICD7 with the the recommended pea method. When I removed to redo the thermal paste, everything seemed fine there was an even spread. Clean it with 91% Isopropyl Alcohol and then reapplyed. I tightened the cpu in a star pattern. The fans and heatsink are clean and everything. I just don't get it?

    the sucky thing about the g50's thermal management system is that it doesn't really kick into gear until the gpu reaches 75 degrees. Another possibility is that the replacement fan you have could be faulty as well. I have an extra fan here that I could send to you if you'd like.

    How do I check if the fan is faulty. The fan does kick in when I launch a game, but its just not like loud as before. Is there a way to check the fan's performance. If the fan is indeed faulty how much would it be to ship your extra fan. Because these temps are just worrying me. Thanks by the way!

    If you're 100% that your paste job is done properly, then I'd assume your heat pipes aren't making good contact with your heat sink.

    So how do I tell if the heatpipe is making good contact with the heatsink. Also the reason temps where high before was due to updates. The correct idle temps are these.

    Idle
    CPU: ~55
    GPU: ~71

    But even with these idle temps they only match my other g50v. Which is still relatively high for a laptop. What temps are you guys getting on a stock g50v?

    Try using something like RivaTuner to downclock your GPU on start up.

    To make sure go back in and repaste again. If you can do it once you can do it a second time.

    You might just do exactly the same job and see different temps. Too much paste could be the problem causing a lack of thermal conductivity and its amazing how little you need to get the job done. I used to worry and use a good helping worrying it would not make contact and using minimal made a vast difference in temps especially with ICD because the heatsink could just be sitting on top of the thick paste.

    Dont downclock to prevent the temps rising a bad paste job can over time have bad results.
