Currently it is version 0.1 and does basic temperature monitoring of up to two NVidia GPU's.

It updates approximately every 500ms.

It can be minimized to the system tray where hovering the mouse over the icon will display a tooltip with the temperatures detected.


Windows XP 32b or 64b - it will probably work on others but I have only tested on these (no Centos / SuSe versions yet - but I *may* eventually get around to them too)

NVAPI.dll must be installed - it gets installed along with your NVidia video drivers by default


Known Issues:

It only handles 1 or 2 GPU's

It plots the graph a pixel at a time - so if the temperature varies quickly you end up with non-connected dots

The odd repaint issue - actually only seen this once and it may have just been my OS.

I'm sure there are lots of others!


Future Improvements:

Better graph drawing

Configuration file allowing changes to update speeds / skins / GPU's to monitor

Always on top button - so other windows cannot overlay it

Network reporting - in order to query temperatures of remote GPU's

Code Changes:  Move the graphics positions and other values to constants and config files


To build you will need to modify the paths in the make file to the ones relevant to your system.

Enjoy and please let me know of any features/enhancements you would like to see. As always let me know of any bugs!  :)  You can do so by commenting, emailing or visiting its' forum topic here


  1. Thanks for this!
