No. Unfortunately you can't. I have a compaq pc, and purchased an aftermarket heatsink that screws in for about $15 including shipping from newegg's open box section. It's possible to remove the mounting bracket, but I was too lazy. I happen to see this item listed; it was the same brand as my original heatsink (AVC), so I ordered it. A few other brands screw in; you'll just have to check. Newegg gets in new open box items about once a week.
