If you mean this, just cut the heatpipe and add a small fan. Zip ties and coat hangers ftw hehe.
NOOOOOOOOOOOOOOO!!!!!!!!!!!!
Don't cut the heatpipe ever. That heatsink won't cool crap without it. Plus, if you ever need to RMA, you'll need to get another which is pretty much impossible. Bad bad bad bad bad bad bad bad bad suggestion.
Get some good ramsinks, like the Swiftech ones for VGA memory and put them on there. They will do the trick. Besides, the moffsets don't need major cooling anyways as long as you have decent airflow.
