Did you try the Via Cooling tweak??? (it is in the tips and tweaks section)
It really does lower your processor temps (as long as your processor is not running at 100%)
I have a Thermalright AX7 (Less than $20) heatsink and not only does it really keep things cool, but by using a nice big 80mm fan on it my computer is very quiet.
I noticed that one of our associates/supporters
http://www.jab-tech.com/ has a great deal on a Thermalright SLK-700 + Fan whch is pretty hard to beat performance/pricewise:

(that should be WAY more than enough for your 1.2 (probably overkill, but then you could probably overclock the hell out of it..Hehe)
Very effective, Very quiet (depending on the fan you put on) and one hell of a lot cheaper than water cooling.
