    Hi, so I recently got my motherboard replaced because my 8400M GS crapped out on me. The thing is, now I have overheating problems with the new card that I never used to have before. Games that max out the GPU quickly cause it to overheat within a few minutes (~98C), causing frequent slowdowns. I'm not sure that the downclocking works the same way with all the cards, but I recall going over ~100C on my old card without any downclocking (not that that's a good thing). The same games run on the old GPU only pushed it to around the mid 80s, so something's definitely up. Also, my fan seems to go at full blast when my graphics drivers aren't installed, or in safe mode (even though the GPU is cool and cold air blows out, but still reads ~90C for some reason). I'm pretty sure it's not a dust issue, since it has happened from the time the laptop was fixed. Can I fix this problem or will the GPU need to be replaced again?

    when the GPU reaches a danger temp (usually above 95C), the GPU will downclock itself to prevent further damage from overheating.

    the issue might be is that your GPU (Nvidia 8400M GS) is one of a few marked my Nvidia to be faulty.... which you should send back to the manufacturer to try and get a new and non-faulty one.... but a number of people that have sent it back also got another bad GPU (since there was a large batch of faulty cards)

    They must have replaced your old faulty card with a new faulty card :rolleyes: .Or it can be that they did not re-install the cooling solution properly after replacing the GPU. You will find some guides here on how to check this. You should check if the thermal paste is properly applied.

    If you are not confident, I recommend sending the machine back again.

    I have the same problem as u. My GPU can overheat to 90-95C easily when i play cod4 so i got a simple solution for the problem. Raise your laptop off the ground and blow air underneath it using a big stand fan. It reduced the temperature of my gpu by 20++ and not to mention kept the rest of my computer cool
