[NVIDIA] Overheating since kernel/driver update to 2.6.36/260.19.2

The pb for my laptop DELL M1210 is not new (since Debian Sid when I was blocked with kernel 2.6.32-trunk). Changing to Arch some months ago, the NVIDIA Geforce 7400 GPU temperature came down to 74°C (gnome+compiz). It was still too hot but more reasonable than 93°C with Sid if I would have followed the kernel updates.

Last week, the kernel update .35 -> .36 and the corresponding Nvidia driver gave me additional 20-30°C, means 95°C (I'm just using firefox without anything else in background). By browsing (pad scrolling), I reach easily 110°C ***scary***

Since, I cleared all in xorg.conf -> no improvement
I desactived compiz -> nothing better

Before testing some exotic options (for a newbie like me) in xorg.conf/device, I would like to understand what's happening, as for example with some commands to monitor the gpu activity (ps or top equivalent), to be able to identify the reasons of that permanent GPU overheating.

To avoid to burn the motherboard, I've temporary downgraded the kernel (and Nidia driver) to .35, and recovered 30°C immediatly down (back to 75-80°C).

PS.: the CPU is quite: 44-45°C

It seems like a hardware problem (the notebook fan maybe ?). 74 degrees ? It's too much already. 110 destroys the card.

Odd... temps don't seem right at all.

Do all those give the same temp?

Hi!

It's strange, I've had just the same problem with my pc with Geforce 7600 GPU. It looks like it was because of the fail of the passive cooling (I have Zalman passive cooling instead of the original active), so I put back the original. Now it's just fine. I know you can't do with this with your laptop by yourself, but I think you should take for servicing. But it's strange, that we had the same issue at the same upgrade...

Well, you have a laptop and laptop needs more maintenaince than a desktop. You HAVE to open your laptop and clean all the dust on the fans at least once a year, if you dont do that it will start overheating with reduced batery life and performance. Also your thermal paste is probably melted at that temperature and it won't be so efective.
Your GPU can handle 100ºC, but not more than that. You should be in the 50ºC while idle... 80ºC is still way too much. So it's for sure a cooling problem, probably caused by dust.

I have the same video card
kernel 2.6.36.1 (zen2)
video driver 260.19.2
KDE with stuff enabled

current video card temp is 42C

as suggested already: clean dust from fan/video card. This is most probable reason for overheating aside from failing video card fan.

This can make CPU stay hot https://bbs.archlinux.org/viewtopic.php?id=109371. kworker has many wakeups since last kernel update.
