Thank you all of you for your brilliant explanations.
I have the same problem with my HP Pavilion dv6 notebook.
My HP lapotp has an OEM cooling system(fan/heatsink assembly)(the final four screen shots below).

1. I have removed the old fan from heatsink, and then cleaned the old fan with a paint thinner.
2. I have cleaned the the exterior vents(airways) of heatsink by blowing a compressed air through them.
3. The cooper pipes can never be blown by a compressed air, nor even are they cleaned with any way since they are closed from all of their ends. The ends of the cooper pipes are soldered to the exterior vents(airways) of heatsink.
   
4. I have removed the old thermal compound, and applied new one on both CPU and GPU
5. I applied a dot of fresh paste to the center of the CPU and GPU, and spread it. The method I go by is slightly bigger than a grain of rice but smaller than a pea. Then, put it back together.
6. The new thermal compound I have used is
   ZP-360 heatsink compounds for CPU heatsink compounds for motherboard chipset 30 gram easy-tube pak"]ZP-360 heatsink compounds for CPU heatsink compounds for motherboard chipset 30 gram easy-tube pak
7. I have then mouned/heatsink assemply, and screwed down.
   

However,

1. the error 'the system has detected that a cooling fan is not operating properly' still appears to me.
   
2. the error, which is related to discrete AMD GPU, and not CPU, still sometimes appears to me.
   
   
3. My laptop's CPU and GPU are still overheating, although I have bolted the fan correctly in the heatsink.

The speedfan utility doesn't help me check anything at all, so I think it is bad design..





My fan/heatsink assembly is OEM cooling system unit. However, I found a new single fan(not fan/heatsink assembly) whose the first two screen shots are posted below are not OEM unit. I haven't installed the new fan yet. So, you think if I had replaced the old fan with a Non- OEM unit, the fan would be working well, or my laptop would be still overheating? NOTE: that new fan costs me for $50. So, if my laptop would be still overheating after installing the new fan, it would be a big problem.
