High Temps, Should I Re-paste? [Laptop]

Poll Results: Are these temps too high?

    Yes, you should re-paste.

    Yes, but re-pasting is not the problem.

    No, but re-pasting will most likely yield lower temps and you should do it anyway.
  • 0% (0)
    No, and re-pasting won't make a difference. Leave it alone.

A month or so ago I busted a USB port on my laptop. I had a warranty with accidental damage protection, so I had it fixed. However, this required replacing the motherboard entirely. As such, the heat sink and CPU were removed and put on the new board. I watched the tech do it, he just took the heat sink off, dropped the CPU into the new motherboard, and screwed the heat sink back on. He didn't clean and re-paste the heat sink.

So now to the point. When monitoring with core temp, I sometimes reach temps over 90C. Usually this is only when running CPU and GPU under load, they share the same heat sink. The GPU will hit low to mid 80s. Are these temps too high? Should I try re-pasting the heat sink? I know how to do it, I'm just not sure if that's the problem. What are acceptable temps, both for CPU and GPU? The Tj Max is 100C, but 90 seems awfully high. My CPU is a i7 2620M, which is a mobile sandy bridge. My gpu is a radeon hd 6470M.
Now, these temps would be insane on a desktop chip, so please keep in mind that is a laptop.

Oh yeah, you need to re-paste it yourself. The only way I would ever use paste again and not clean it, would be to test something really quick. Even then tho, I would still clean and re-paste. And with a laptop..... 100% clean and re-paste because it can take a little while to open it back up and re-assemble correctly
I went through an entire tube of AS5 getting my water loop done correctly, but at least I didn't fry anything in the process tongue.gif

To answer your question tho, yes. If you feel confident doing it, I would highly advise doing so.

If you know how to do it then you definitely should. I just just repasted mine last night. I broke the pin to the power plug and replaced the whole jack, but while I had the motherboard out, I must have shifted the cpu heatsink around because when I got it put back together my temps would jump around drastically and when I went to play GTA IV, it shut down due to overheating, and a few seconds of Prime95 resulted in immediate shutdown. So, I did the paste on my cpu and gpu and now I couldn't be happier, and I lived happily ever after, the end. The tech guy was being lazy and should have cleaned the cpu and heatsink, with fresh paste, period. Clean it very gently.
