That fan will work, it won't be better than an average stock HSF that usually comes with the CPU. Didn't you say in another thread that your CPU didn't come with a sink or fan? You won't get mad-cool temps with this if you try overclocking your E6600, but it should be fine for you if you're just looking for a budget solution to finish up your build. These chips run quite cool compared the the old Netburst-class chips.
