Best cooling for $500 or under?

[003]

I am thinking of possibly moving away from air cooling. If I did, I would spend up to $500. What I am worried about though is that all the other types of cooling seem to be very high maintenance compared to air. What I would be looking for in the new cooling would be: Cooler than air, will work on at least my cpu and gpu at a minimum, at least as quiet as quiet air, and as low maintenance as possible, again for a maximum of $500.

What type of cooling should I be looking for? Does anybody have any useful links?
