I paid 63.99 actually for it. And heres how I have it going, I'm going to run an experiment to see which one is better.
Right now I have 2x 80mm case fans on the back blowing air in. Because its average of 67 degrees farenheight in my house and the zalman I have blowing air in the same path. Right now I Idle @ around 30 and load around 37/38. Which isn't bad at all. Within another week I am going to flip flop them both and see how that turns out... But right now I couldnt be happier. Up to you though.
