What new cooler for T43p (2668-G1U)?

[lukee]

Hello,
I am not able to decide, what type of new fan I need buy for my T43p lappy.

First: FRU 26R9074, covering ATI graphics core also, not covering north bridge
Second: FRU 26R8197, covering ATI graphics core + covering north bridge chip (I don't know, if this type is correct, because ATI core & NB core are in different level over motherboard)

Could you recommend good type of fan which will be silent & able to cool down components & suitable for T43p 2668-G1U? Thank you!

edit: I forget to say, that it is 14" model.
