I got something to fix with edit on SMonitor (karamba) except with the temperature??? I read other from other site and tried to set up etc... I got lm_sensors and installed... but I can't find any instruction on how to edit or configure to make it running??

You will have to run in a console, as root, "sensors-detect" (without quotes), and configure your sensors.
NOTE: your computer may or may not have some or any sensors!!!

When you run (as root) sensors-detect, the utility will guide you through the detection process. However, in most cases you must edit some files as per the final sensors-detect output. Please see this section of the wiki: lm-sensors.org/wiki

Then you can select a karamba theme that works for your needs.

Guys... I think I made it... my karamba now showing Core 0 and Core 1 Temp, but only one left is GPU Temp... Do you know what it is?? It only showed C degree...

If you're using a laptop, you may not be able to read the GPU temp. Not all laptops have a sensor to read it.

GPU is your graphics processor, your video card's processor. The detection method depends on the type of your card. Open up the karramba theme and edit it to fit your needs:
1) if you have a PC and nvidia video card, you may use a nvidia-settings command with some parameters to detect the temperature
2) if you have ATI card in your PC you will have to use another ATI specific utility
3) if you have a laptop, you may NOT have a temperature sensor for video card (which is on-board), usualy laptops don't have it.

Also, you may have extra sensors which are NOT in your karramba theme. I use "RessMon" theme, and I edited the file to add:
1) harddisk temperature
2) motherboard temperature
3) 3rd sensor for processor (CPU), I have core0, core 1 and cpu

Cool guys! I will do the text edit to remove GPU since it is no use in laptop... But I might add in for motherboard, I think that would be cool... I will look for it and then add in the one I tried to create...

Many thanks!!
