Re: Best Am3 socket cooler?
one easy and cheap thing you could do, although it'd increase your temps slightly, is get a Zalman fan speed controller (they often come with their coolers, but I've bought them separately too). Run the CPU fan through that, and you can dial its speed way down for quietness, and turn it up higher when you need better performance, like when gaming, and there's enough other noise that the fan won't be noticeable. it's what I've got on my setup, works really well. I don't know what my low speed/high speed temp difference is though.

I'm running a Phenom II X4 940 using a Zalman 9500 cooler. Don't know if it's too tall offhand, but it works. Runs a bit warm though, way warmer than the older dual core I originally bought it for.

cheap, and incredibly cool for the price. 15mm below your height budget.
