Hello all and thanks in advance for your suggestions

I know the chirping fan noise issue has been addressed in other posts but ... what I'd like to find
is how to get to the computer cooling fan. Is it something that I can do by myself or should I take the car
to a dealership ( I hate doing this - no warranty left )
If I can get to the blades and clean them off + lubricate the axle - I should be OK ( I guess)
So..how do I get to it ??
