a while back my 2,5 years old ASUS N73SV started to overheat, so i took it to a full 100% dust cleaning service, but its still at the same temperatures as before.

It is a really good pc, and works well, but i am worried that it will "burn up with time".
WHen i asked ASUS in their customerservice, they just said that it had no warranty anymore and just told me the basic temperatures: "In normal use the normal temperature is aroud 40 and when playing the games the normal temperature is around 80."


The temperatures are like this when idle: (gathered by Speedfan and Speccy)

(speedfan) These temperatures variate between this level and +10
GPU: 54C
HD0: 33C
Temp1: 86C
Core0: 81C
Core1: 85C
core2: 83C
Core3: 82C


(Speccy)
GPU:
Intel Core i7 2630QM @ 2.00GHz 85 °C
Sandy Bridge 32nm Technology

Motherboeard:
ASUSTeK Computer Inc. N73SV (CPU 1) 88 °C

So my main question is, since its 100% clean for dust, and its idle with minimum of processes running (i think...) What might the problem be? i'd really want to keep this laptop alive, even the pc geeks nearby honor it for its amazing capabilities as a "desktop replacement laptop"

Between the CPU and the cooler, there is a very thin film of thermal paste. This helps transfer heat from the CPU to whatever cooler is in there. I suspect it is either bad or old.

Take it apart down to the motherboard. Unmount the cooler on the CPU. Clean thoroughly (90% isoproyl alcohol and coffee filters). Apply new thermal paste. Reinstall. Put everything back together.

Go slow and take notes as you go.

I'm sorry but i dont have that much experience in hardware.... what might be wrong with it/how do i check it/how to fix it? Thanks for answer by the way, now i'm at least not 100% clueless

And i don't know if it helps, but it shows my motherboard is working at 100% all the time, while the total CPU usage variate between 65 to 90%

Thanks, that might be it when thinking of its 2,5 years old age..... i have had some serious problems openingit though, but i can ask the nearby geeks to do it (the ones that cleaned my computer for dust)...... but of course i will ask if they did it when they cleaned it, so i wont pay them twice.

If all they did was blow out the dust, almost certainly they did not replace the thermal paste.
