My Qosmio X870-14T heats up in 10 minutes

Question

Hello.
I got Qosmio X870-14T. It heats up in 10 minute even i play most basic games and shuts down. CPU heat reaches 90 and it closes. I send it to warranty 3 times in 2 month. They update it and just send it back. Toshiba just dont care.
What can i do guys? I realy need to fix it. But in my country Toshiba support is horrible.
What can i do to fix it?

Answer 1

Hi
Generally the notebook would overheat because the internal parts produce too much warmness or the internal cooling modules dont run properly and cannot cool down the internal parts.
Why internal parts would produce too much warmness? Well, this can be possible if you would use graphic drivers which are not designed for mobile usage.
For example drivers from nVidia or ATI dont support GPU overheating protection. Such drivers allow the GPU to run with best performance (if necessary). This could lead to more heat dissipation and finally to overheating.
GPU drivers released on Toshiba pages are modified for notebook usage and support such kind of protection.
Why cooling fans cannot cool down the parts?
Mostly because of dust inside the notebook vents. It could be also possible that cooling vents and fans are clogged by dust and cannot rotate properly and air cannot circulate as it should. In such case the notebook should be cleaned.
Finally it could be possible that thermal grease which is placed between cooling module and CPU isnt good enough or dried out. This would also affect the CPU cooling and would lead to higher temperature.
So as you see there are many reasons why notebook could overheat.
