find out GPU temperatures

[nerdinator]

I have an Nvidia GT 540M graphics card in my Dell XPS ,whose fan is making a lot of noise.
I want to check the GPU temperature.

I did

sudo apt-get-install lm-sensors

and ran

sensors

.

It only gives me

Adapter: Virtual device
temp1:        +95.0°C  (crit = +100.0°C)
temp2:        +95.0°C  (crit = +100.0°C)

nouveau-pci-0100

Adapter: PCI adapter

temp1:        +72.0°C  (high = +100.0°C, crit = +110.0°C)

How do I find the GPU temperatures?
ps : what is "nouveau-pci-0100

Adapter: PCI adapter"?

nouveau is an open-source driver set for Nvidia cards. Unless much mistaken, that is your GPU temp.

And it is running very hot. My laptop has an nVidia card in it that runs very warm, but it rarely shows more than around 80°C for any of it's sensors.

I think it is time to consider opening the box and blowing out the dust, and maybe renewing the thermal paste between the heat sink and the hot bits.

A+ to Audiomick

You can install "psensors"

  sudo apt-get install psensors

It show gpu temp and is just a gui for the terminal output.

install it, open it up, select what you want to display , then you close the window and there will be a thermometer icon in the top toolbar that you can click on

this way you don't have a terminal open all the time

Try running:

sudo sensors-detect

to make sure that all of your sensors are properly configured.

You can select the default for all answers but answering yes to:

Do you want to add these lines automatically to /etc/modules? (yes/NO)

Will save you from having to do any manual configuration.

After a reboot run 'sensors' again and you should get a more detailed output.

nvidia-settings -q GPUCoreTemp

if you are using the closed source driver

me@lucid-desktop:~$ nvidia-settings -q GPUCoreTemp

  Attribute 'GPUCoreTemp' (lucid-desktop:0.0): 28.
    'GPUCoreTemp' is an integer attribute.
    'GPUCoreTemp' is a read-only attribute.
    'GPUCoreTemp' can use the following target types: X Screen, GPU.

you can open nvida-settings and go down to "PowerMizer" and "Thermal Settings"
if you are using 2 or more screens disconnect one and log out and in the temp should drop some (drops 5C for my moms system)

thank you for you replies.
@audiomick, it is very new laptop. I don't think dust should be an issue.
@jmfal , I did that. Thanks
@CheeseMill, yes I do get a more detailed output now.
@pqwoerituytrueiwoq , I get this when I open nvidia-settings,

You do not appear to be using the NVIDIA X driver.  Please edit your X configuration file (just run `nvidia-xconfig` as root), and restart the X server.

and no I use only one screen (my laptop's).

Turns out,after the restart, it got cooler and the fan sound is gone.

acpitz-virtual-0
Adapter: Virtual device
temp1:        +65.0°C  (crit = +100.0°C)
temp2:        +65.0°C  (crit = +100.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +57.0°C  (high = +86.0°C, crit = +100.0°C)
Core 0:         +57.0°C  (high = +86.0°C, crit = +100.0°C)
Core 1:         +57.0°C  (high = +86.0°C, crit = +100.0°C)
Core 2:         +57.0°C  (high = +86.0°C, crit = +100.0°C)
Core 3:         +57.0°C  (high = +86.0°C, crit = +100.0°C)

nouveau-pci-0100
Adapter: PCI adapter
temp1:        +56.0°C  (high = +100.0°C, crit = +110.0°C)

Core 0 to 3 must be the 4 cores of my quad core processor ,if I'm right.
and nouveau-pci-0100 is the GPU's as MG&TL told.

What are temp1,and temp2?
