I am with the above, if you have the space, 212+(on sale all the time, but newegg seems to have the 212 evo for the same price) or 212 EVO. The TX3 is a 92mm fan based cooler and the 212 is a 120mm fan based cooler.
Easy install and should sound better then stock(Plus you can overclock in the future ).
Nope. Its my media center pc. It is inside of a slightly modded SG05 case(With a slightly modded Geminii S cooler and Scythe fan).
Now days it has a Globe fan(Stock SG05 case fan) on it because I found the second hard drive to be too loud for my liking and the power supply has had its fan swapped and the fan grille removed to promote better air flow.
Zalman coolers while not all bad are overpriced for the cooling performance in many cases.
I say this as a user with 3 Zalman coolers. My CNPS10X Flex was on a good sale, but my 9500AT gives only slightly more performance then a Freezer 7 pro that cost half as much.
My cooler of choice for price is the Hyper 212 for sure. Easy install and can face any direction even on AMD sockets.
Does your case have a rear 120mm fan? Most with that will fit a 212+.
This is a picture of a Fractal ATX(it is case width i think you should look at) cause with rear 120mm fan, as you can see, the 212 does fit.
Is the IGP heatsink taller them your memory? Any estimate on size?
If you check this site, it gives you an idea of how wide the case is. They have room behind the tray, so room from the io plate to the fan should give you an idea of the space you would need.
