 Posted: Sat Dec 10, 2005 8:21 pm Post subject: CPU overheating ??? |
 |
|
I had trouble with my computer switching off. Approx 20% of the CPU's cooling fins were covered with dust so I assumed this was the cause. I cleaned them and the problem has not reoccured (yet).
However, 20% doesn't seem excessive, especially as the fins were only lightly covered with dust. I would have thought that there would have been a greater 'safety margin'. Also the cooling fan was fully functional.
It's summer here in Australia and the temperature in my study is warm but not particularly hot at the moment.
The CPU is not overclocked so there is no other reason that I can think of for it to overheat.
Should I / can I fit another cooling fan, not necessarily on the CPU?
Can anyone comment on this please? |

| How are you for case fans? Yes, dust can be an issue. But also, it may not be well ventilated. |

| Yes there is a case fan and that was what I checked first. Also there are vents on both sides as well as at the rear. |

| You might need to re-seat your heat sink. If you had bad contact with the CPU core and heat sink overheating will be a big sign of that. Most times the thermal conductive compound has dried up and now there is a small gap between the CPU core and heat sink. |

That sounds highly probable ........... I live in a small rural town and there's no computer shop here - actually there's not much of anything. Next time I go to the city (Perth) I will buy some thermal conductive compound and re seat the heat sink.
Thanks for your help. |

The compound is not really needed. You can just clean it off and place the heat sink directly on the cpu. If you use any thermal compound use it very sparingly. |

I beg to differ, according to manufact. specs, it can make a 5 degree difference. When I was doing power electronics it was SOP to use thermal compounds - it DOES make a difference.
I would agree - use sparingly - more is worse, as the compound's purpose is to 'fill' the gaps within the surface (and not the space between the heat sink, and CPU). |
