Thanks guys. I knoiw what you mean, I wish I can get the two combos to check it out and find out. But it looks like I will be satisfied with the Swiftech, since it seems to be ample for cooling the T-bird. Now for another question: By using passive cooling AKA HSF, what would be my realistic OC speed on an average 1.2 GHz T-Bird? Ofcourse, with hopes that I will not be creating a "EZ bake oven in my computer case.
