This answer is more generic because you don't give more info like if you run a mobile device and what drivers you are use.
First of all, check your module:
$ modinfo nvidia|grep -e Mobile
parm: NVreg_Mobile:int
On notebooks you should have set NVreg_Mobile=1
.
$ cat /etc/modprobe.d/nvidia.conf
options nvidia NVreg_Mobile=1 NVreg_EnableMSI=1
and rebuild you initrd
with update-initramfs -c -t -k all
.
The MSI setting is generally good for memory copy with a fast interface.
$ grep nvidia /proc/interrupts
45: 3969293 0 PCI-MSI-edge nvidia
You should also use the lm-sensors
package, which shows you the
system temperatures, voltages and fan speeds:

If you think your GPU-fan
is to slow, and the particular fan
is listed, then you can use the fancontrol
tool to adjust it.
To read the temperature of you GPU
use:
$ DISPLAY=:0 nvidia-settings -q GPUCoreTemp -n -t
