Default 7900GT cooling needed?

I have my eVGA 7900GT Manual Overclocked via the Display settings to 558MHz core clock frequency and 872 MHz memory clock frequency. It idles at around 53-54C, and after running 10min or so of RTHDRIBL it's hitting 74-75C. Would it be a good idea to get some kind of after-market cooler? What type is best for a 7900GT? I see people mention Zalman as a good name.

temps are fine, only reason to get another heatsink now would be because you don't like the noise.

last night i had my 7900gt out of the case cuz i had to work on some fans and it was in the way. i decided to pop off the hsf and check out the thermal paste. It looked like at least mid-grade thermal paste (grey/silver, but too pastey white to be high grade) I wiped it off (it was kind of dry and chunky) and put some fresh AS-5 on it.

i'd rec doing that... the factory thermal paste is crusty/crappy.

i'm expecting to see at least a 5*C drop
