DV6-6060sa Do I have discrete graphics memory or UMA graphics memory? + Where is 'System Fan 'B''

Question

Hi There,
I am going to attempt replacing a fan on my Pavilion DV6-6060sa Laptop, I have been looking around on the net and have just now read through the service manual to better understand which component needs replacing.
I am going to be changing system fan 'B', as the error message states at start-up. (I have tried compressed air spray through the air vents but this has not worked.)
In order for me to purchase the correct part number I need to know whether I have Discrete memory or UMA memory.
As stated above I have a Pavilion DV6-6060sa unit, the below snippet is from the service manual.
(12) Fan/heat sink assembly (includes replacement thermal material):
For use only with computer models equipped with ATI Mobility Radeon HD4650
graphics subsystems
518435-001
For use only with computer models equipped with graphics subsystems with discrete
graphics memory
512837-001
For use only with computer models equipped with graphics subsystems with UMA
graphics memory
512830-001
Could you let me know which part number I require, and also send me a link for an original HP replacement part please?
The fan I will be replacing is the fan closes to the power button, looking down at the laptop from a birds eye view it is located on the upper left corner. The two vents (one on the left and one on the top) usud to have air forced out from the fan, which is now not working. I take it this is system fan 'B' and is the heat sink?
Please can you confirm the above information?
Specifically Including a description of which fan system fan 'B' is? (thank you)
I appreciate your help, Simon.

Hi,
90B is the error code, not the location of the fan.
