Cooling fan replacement advice for HP Pavilion dv6-6093ex notebook
Hi,
When starting the computer, the following error appears on the screen:
The system has detected that a cooling fan is not operating correctly.
Continued operation is not recommended and may cause unpredictable behavior that could result in random shutdown, data loss or possible system damage. The system will shut down in 15 seconds. To prevent shutdown and continue operation, press the Enter key now.
I followed all steps in this document to fix this error, except the final one which is replacement.
The spare parts need care when purchasing since they must be compatible with my HPCode:This document pertains to HP and Compaq notebook PCs. When starting the computer, the following error appears on the screen: The system has detected that a cooling fan is not operating correctly. Continued operation is not recommended and may cause unpredictable behavior that could result in random shutdown, data loss or possible system damage. The system will shut down in 15 seconds. To prevent shutdown and continue operation, press the Enter key now. System Fan (90b) In addition to this error, the system fan may spin faster and become louder.This error indicates that a problem exists related to the heat removal system. One of two possible events is occurring: .The system fan is not spinning or not spinning properly. .The temperature inside the case is too high and the fan cannot spin fast enough to remove the heat. This error message occurs to help prevent costly damage to the computer. To fix this error, use the following steps: 1. If you notice that the system fan spins and is blowing warm air from the computer,clean the exterior vents to remove dust buildup by blowing air through the vent openings. Do this while the computer is off. Dust can accumulate inside the vent opening and around internal cooling components, preventing the removal of heat.After dust has been removed, try turning on the computer to see if the error goes away.if not, continue to the next step.

Performing a hard reset can reset recorded thermal values in memory and enable you to use the computer again — even if only for a short time to access and save any important files before service. For information on performing a hard reset, see Use Hard Reset to Resolve Hardware and Software Issues . 3. In some cases, updating the BIOS may help prevent this error from occurring. For information on how to update your BIOS, see Updating the BIOS . 4. Have the computer serviced to clean internal components and replace the system fan if necessary. Ensure that the following items are addressed during servicing: .Thoroughly remove dust from all internal cooling components. .Ensure that wires from the system and CPU fans are connected to the motherboard securely.

I was told by HP forum member that my notebook's 'Cooling Fan/CPU fan/heatsink' should be replaced with this HP
Spare part number: 641477-001
Discription: Cooling Fan/CPU fan/heatsink (For use only with computer models equipped with a graphics subsystem with 1024-MB discrete memory.
However, this information written on a sticker on the Cooling Fan/CPU fan/heatsink' sent by a person claiming that he is computer technician.

When I have made comparison between the information on the Cooling Fan sent by that computer technician, and the information on the Cooling Fan in my 'HP Pavilion dv6 Notebook PC-Maintenance and Service Guide)c02842252 below, I found there is no relevance at all between the two cooling fans.
There is no spar part number typed on the fan sent by that person.
Also, When I tried taking apart the first parts of my notebook, such as 'service cover', optical drive, and HDD, I found each of them have an HP spare part number printed on it.
Although I didn't get to the cooling fan, it could have an HP spare part number printed on it.
Since removing the defective cooling fan and replacing it with the new one will be more difficult to change as many parts of the Notebook have to be removed to get to it.
So, My questions are as follows:
Firstly: do think that I can go ahead to install that new fan. I don't want to try to take apart all the parts of my notebook, and when getting to it, and while installing the new cooling fan above, I'll face it isn't compatible or not working well.
Secondly: the new fan sent by that person is only single cooling fan, and there are no other parts, such as thermal material, so why is it said in the final step of To fix this error 'Thoroughly remove dust from all internal cooling components. as long as the fan is only a part?
Finally: I have read in the maintenance guide 'The fan is controlled by a temperature sensor and is designed to turn on automatically when high temperature conditions exist'. So, this is applied for any cooling fan?
