Pavilion G7 1070us cooling fan replacement

I have a Pavilion G7 1070us laptop that requires a cooling fan and attached heat sink unit replaced.  The fan part # is 646578-001.  the heat sink part # is 643256-001.  on the heat sink there is a part # 4gr12hstp80.  I have found the same cooling fan and heat sink as a replacement, but with different part numbers (heat sink part #643258-001, 4gr13hstp80) for sale through a supplier (cost plus shipping charge.)  My question is: has your repair history proven that this cooling  fan will work in the pavilion G7 1070us laptop?  thanks for the reply.

When in doubt, search google images by part number. I have done that and found good photographs of both parts with the respective numbers on HP labels and the parts appear to be identical. You can try it yourself and see if you agree.

Re: Pavilion G7 1070us cooling fan replacement

To clarify my question further: Has your experience working with HP Pavilion G7 1070us laptops allowed you to use different HP part numbers for replacement parts (in my case, i.e. the cooling fan and heat sink assembly) to repair the unit?  I have removed the failed cooling fan and heat sink and googled the part, found it, but the HP part numbers do not match.  Both cooling fan and heat sink assembly parts look identical other than the HP part numbers I can identify on the label.  thanks for the reply.

Re: Pavilion G7 1070us cooling fan replacement

Yes due to different distribution channels and iterations in different machines it is very possible for the same part to be distributed under different part numbers. HP sometimes does not even know this and the big online parts houses figure it out. If it is a reputable parts house and they advertise the part as working for a specific model, you can believe it within normal allowance for error, which is very small. To be sure I have not had experience with this exact combination of parts numbers (that would be a long shot) but can attest that multiple part numbers can refer to the same physical part. This has been true on all laptop manufacturers as long as I have been ordering parts (since about 1997).

Thanks for the reply.  Your experience helps me in making a decision about investing time to use the delivered part for attempted repair.  Check back on jul 21 for results and details on part #s used.

Re: Pavilion G7 1070us cooling fan replacement

part was not a match.  continue to look for a cooling fan and heat sink for this laptop model Paviliion G7-1070us with an intel i3-380m processor with the cooling fan HP part # 646578-001 and the heat sink HP part # 643256-001.  please leave reply with the website.

Here are the specs for your HP Pavilion g7-1070us Notebook Computer. Here is the HP Pavilion g7 Notebook PC - Maintenance and Service Guide for your computer. Based on this information your computer requires HP part numbers;

 

639460-001 - FAN module  and  637189-001 - Heatsink Module - UMA HM55

 

From the HP g7 MSG;

And from the HP Partsurfer for your "HP PAVILION G7-1070US NOTEBOOK / LF156UA";

Both of the above parts are available for purchase at the HP Parts Store.

part numbers matched. part ordered.  will install.  Thanks and Blessings to Kyle.  I will be able to repair the laptop finally.  To date, it has been a month of working on this project that I thought would take an evening.

My bad and sincere apology. The chance of error was not so small after all. I will note that the part lasvegaswireman is referencing is not the same part kyle is referring to.
