That is FAR too hot, that will significantly shorten the life of any processor, and at the very least cause it to spew errors and bad data. I would be surprised to see any processor last over 2 weeks with that temperature. The motherboard temperature seems fine. Sounds like your fan/heat sink might be fine, but the critical part in all of this is the thermal paste that sits between the die on the CPU, and the heat sink. Take it all apart. Scrape off what you can from the cpu and heat sink. Then, use light rubbing alchohol on rags to clean it up as good as possible. I would also use a very fine sand paper on the bottom of the heat sink. But NOT on the cpu die. A few seconds of very light pressure should be enough. A key is to use GOOD thermal paste, not some no-name store stuff. I always go with Arctic Silver. Remember, the thinner the layer, the better it will conduct heat. If it is too thick, it will retain heat in the CPU. The way I pull this off is apply the thermal paste on the entire die of the CPU with the very edge of a new razor blade. Assuming your heat sink is reasonable, and your fan is reasonable, you should notice a significant heat drop. If you don't, then that means that the case itself is not circulating air properly. Have at least one fan, on the back, as high up as possible. Two is better, again on the back. You can go overkill with fans. The thing to remember is you want the same ammount of air coming in, as going out, to get a good balance. If you have more air coming in than going out, heat will be held in. Something else that helps a lot, if you have a tower, is using a power supply with a fan on the bottom of the power supply, that pulls up. Then, the fan on the back of the power supply pushes that out. Hope this helps. Do this SOON, or you WILL destroy the CPU. It's also likely the CPU is permanently damaged, already, and may need replaced. Good luck. -- gentoo-user@gentoo.org mailing list
