I trying to work out how long can my graphics card last with its fan off without overheating.

when I'm browsing the Internet, the graphics card fan is the loudest thing in my computer.

So my question is, how do I monitor the GPU temperature of my ATI Radeon HD 4850 graphics card.

it has to do with ubuntu or linux because i want to find a program compatible with it that will allow me to see my gpu tempurature –  Nick Bailuc May 6 '12 at 5:37

Not long until it fries. Depending on the amount of graphic workload you're doing, manufacturing process, accumulated dust could be minutes, hours. buy an aftermarket fanless cooling replacement if noise is a problem.

To monitor your GPU Temperature, use this Q&A to help find the GPU sensor:

How to use to use lm-sensors?

I just cleaned my graphics card from dust today, and no there will be almost no load on it, since all ill be using is like firefox. Im asking how long will it last without causing ANY damage at all? –  Nick Bailuc May 6 '12 at 4:35
    
Of course it will cause damage, heat causes damage to all electronics under extended periods of time, the card can get to ~120°C and it's supposed to shut off or it will fry. I'm certain no one has ever tried to just burn a card just to see how long does it takes too happen.. –  Uri Herrera May 6 '12 at 4:41
    
but would it last 20 seconds? –  Nick Bailuc May 6 '12 at 4:44
    
I'd guess it can hold up 20 secs, you can install lm-sensors to monitor the temp so you don't get past the threshold. –  Uri Herrera May 6 '12 at 4:46

If you are using the proprietary driver (fglrx), then the command you want is aticonfig --odgt.

So far as I'm aware, for many cards this sensor will not be exposed through lm-sensors.

and aticonfig --odgc for GPU load (current usage %), along with clock speeds –  MestreLion Mar 1 '13 at 17:24

Firstly, (See http://www.unixmen.com/howto-install-ati-display-driver-in-ubuntu/ to install) then type

sudo aticonfig --initial

Then

aticonfig --odgt

OUT:

Default Adapter - ATI Radeon HD 5700 Series
                  Sensor 0: Temperature - 45.00 C

Do modprobe it87 and if you are lucky, lm-sensors will give you the info.

If the card runs really hot, you can try to reduce its performance (if the drm module allows that):

echo low > /sys/class/drm/card0/device/power_profile
