How do people cut these mini-sinks up?

post #1 of 9
Thread Starter 
I've seen images in the past where people have cut these in half or even quarters to make them smaller:

I was wondering if anyone knew how to cut them up / what tool people usually use to do it?

Honestly if they're made of pure copper they'd be relatively soft. A good set of wire or bolt cutters might do it, then clean up the results with sandpaper.

I'm sure others have somehow used a Dremel, but using an abrasive disc on copper really wouldn't be advisable.

I have seen people using a dremel to cut up a larger one into smaller ones. If a powered dremel is not available, just a metal saw (see pic below) can still do the job. Just takes more time.

One word of caution: tiny bits of copper might fly off during cutting. Do make sure you have enough protection (especially eye goggles).

Best option, cheap and effective.

Hacksaw, as pictured above. Being a hand tool, it moves slowly - as slowly as you draw it. Far fewer problems, far less debris, far fewer damaged heatsinks.

You mean to cut these Enzotech MOSFET heatsinks even smaller than they already are?

I took a picture just to make sure you know how small they are.



Did you mean the VGA heatsinks?

Yeah, there's a bunch of real small stuff on my card that gets REALLY hot. Plan to sink them with either 1/2 or 1/4 of those like this guy did:
