Overheating Video Card

Postby Forty- on Fri Jun 26, 2009 7:05 am

Hello,
I have nvidia GeForce 9500M GS in my laptop and when I run Linux Mint 7 it overheats terribly :( Temperature is cca 90 C. It must be definitelly running in the "perforamnce3D" but under windows it heats only when I play some modern 3d game ....
IF anyone has idea I'd very welcome it.
Thank you

Linux Mint is funded by ads and donations.

Where are you getting 90C video card temp from? I suspect that is wrong because the chip should almost be fried by now at that temperature. Most chips are rated at 100C MAX. I suspect whatever is giving you the temp readout is incorrect. What % CPU are you running at and what is your CPU temp?

Hello all - sorry it took me so long to respond
I have SOLVED this problem :

First off all some basic information :
Video Card - nVidia GeForce 9500M GS (512MB)
As you might know - geforce video cards have 3 modes :
a) 2d (low)
b) balanced 2d-3d performance
c) performance 3d
The higher mode selected - the higher clocks for GPU core and Memory are used
The problem was that nvidia x server did not start therefore my card was still in performance 3d mode and heating like hell (90 C - fan was doing its job so that card wasnt overheated but the noise ... that TERRIBLE noise ... )

So here is how simply it might be solved :
1. switch to root :
Code: Select all
sudo su -

2. type
Code: Select all
nvidia-xconfig

If you are not root you'll get this error message : ERROR: Unable to write to directory '/etc/X11'.
Otherwise backup will be created
3. close all windows and press CTRL + ALT + BACKSPACE ... let mint login as user (default : mint)
4. now nvidia x server should work - run it (from control center) and PowerMizer tool will do the intelligent VGA management for you :)

Hope this will help to someone!

Glad you worked that out and I learned something new about the newer nVidia cards. Thanks for posting your solution for others.
