And sometimes even Intel R HD Graphics 4000 is not appearing...

Try a different software:

Hi FarazAbdullah,

It appears you are using N5520 laptop with Switchable Graphics. The Intel HD graphics is the primary video device and is a low power solution for day today activities on laptops like internet browsing, word processing etc. It helps increase the battery life of laptop. The AMD graphics card is high performance solution for gaming, designing etc. With the help of Switchable Graphics you get the best of both worlds and effective power management. For normal usage Intel HD graphics is used and for high performance needs the AMD graphics card gets activated when you are using a graphics intensive application or if, in Catalyst Control Center, you have defined a particular application to use the AMD graphics card specifically.

For more information on Switchable Graphics you may refer to the link : http://bit.ly/aCGqbR

So the HWmonitor is correctly displaying the GPU temperature of Intel HD graphics and it is working as designed.

Hope this helps. Do reply if you have any questions.

@FarazAbdullah  -  AMD has a tool called - AMD system monitor which is located HERE it will provide you what you are looking for.

Edit: Also another tool called GPUZ located HERE will provided even more information.

Cheers

Thank you. Already tried it, but no use... it is only showing CPU and Hard drive temps.

@DELL-Sundeep B ... I am finally getting seperate temperatures for Intel HD 4000 and Amd using GPU-Z, but I have to run a high performance application alongside otherwise GPU-Z stops responding...Intel HD temperatures are usually a little (about 3-8 degree c) higher than AMD's... last night i played Bioshock Infinite for about 40 minutes and GPUz was showing about 75c for Intel and 65c-67c for AMD.. is this normal? what is the limit I should be worrying about? Thank You

Thank you everyone for your replies :)

@FarazAbdullah - found another free tool that will more then likely provide you with the information that you are looking for and then some.

Have a look at http://www.hwinfo.com/

@CyberMaxX360 thanks but, already tried that one. Tried many tools. Some are working like GPU Z, but I have to run a high performance application alongside. i have assigned High Performance GPU to Intel Turbo Boost Monitor and whenever I have to look at temperatures, I run it alongside GPU Z and it works. Its oky, I can live with it 'Alhamdulillah, All praise is to Allah'. Thank you everyone. Assalam walaikum. :)
