a hack saw works real well,but make sure to place it on a piece of flat wood so as not to distort or warp the flat mounting surface and clean burrs of cut edge with sandpaper or file. dremmel tool also works well with a cutting blade attached WEAR goggles or safety glasses as the blades are thin and can shatter if forced cutting can be slow on thicker parts. i use my mitre saw (expensive unless you know a carpenter with one) and cut slowly. good luck be careful

I use an Exacto Saw, available at hobby shops. It has a very strong blade. Although it isn't made for sawing metal, I have used the same one for years and for some reason it's never gotten dull. It has fine teeth and is thin. It cuts cleaner than anything I've ever tried.

I've never tried to work on a heat sink but I would also suggest a Drummel Moto tool or the Black and Decker Wizzard (cheaper). Drummel has some fiber-glass, reinforced cut-off discs which should do the job. I've used them to cut steel sheetmetal (which actually I don't recommend) but the disks ought to work fine on aluminum.

A B&D Wizzard only costs about $50 and the Dremmel reinforced cut-off discs cost about $7 for 5 discs. The Wizzard comes with cut-off discs but they are not the reinforced type (might be ok for aluminum).

As the other respondant mentioned, wear safety goggles. Also, be careful, the tool can slip (especially if the disc binds) and you wouldn't want your other hand in the way.

yes, a rotary tool with a cutting disk works well. I also have used a jig saw with a blade for cutting thick metal.
