Hello everyone,
I got myself a laptop a few weeks ago and until now everything seemed to work okay. I set up Bumblebee for Optimus and could run Heroes of Newerth without problems. Recently I updated the drivers, and when I ran the game everything went laggy and soon thereafter (seconds), before the game even fully loaded, the computer turned off due to overheating. This is when I put my hand on the side of the keyboard (where there's some aluminum) and nearly burnt my hand!
There doesn't seem to be any permanent damage, but how can I be sure?
I reinstalled everything graphics-related and it seems to work now. I must have not updated all the packages properly from the AUR.
I've never paid attention to the temperature, and I've been looking at it now; is 96--99 °C normal with a game running for a few minutes? I check it with `acpi -V`.
The specs of the machine are:
Model ASUS K53SV
Intel i7-2670 @ 2.20 GHz
Nvidia GT540M
8 GiB RAM
500 GB 7200 RPM disk
(Edit) Some further clarfications:
A week ago, I don't think the machine got this hot. And that's after a few hours of ingame time. Maybe an update did this? Also, nvidia-settings reports that the card temperature during gaming is about 90 °C. Again, no idea what the normal temperature is.
The temperatures already rise when in the ingame menu and practically stay that way constantly. Is there some "bad" programming afoot that needlessly stresses the machine?
(Edit)
The CPU temperatures don't go crazy if I run the game with the onboard Intel video card. CPU load may be caused by copying the data from one X server to the other because of Optimus. But I don't see this being so heavy (99 °C heavy).
(Solution)
Aha! I installed the 'nvidia' package from the official repositories, which replaced 'nvidia-bumblebee', and this solved my issues. Now everything runs ingame at a stable 70-ish degrees Celsius. I also removed the kernel option pcie_aspm=force, but I don't think that did anything.
