Sorry about the belated reply. Abit shipping charge $6 plus Pay Pal $5 totals $11. As you may already know, you don't have to remove the MB. Ya just need narrow nose plyers to unhook the wire from the wire holder. It was so easy: I spent 30 minutes thinking about it, and then when I got my courage up, it just took 10 seconds to actually do it.
The replacement heatsink/fan unit is about 1/2 the height of the original. It appears that positioning the fan closer to the heat source makes for better cooling.
