It's aluminum, so I don't think that will be very hard:

a fan would work better than a heatsink.

I re-purposed one of the stock SD4 fans for the X motor (the one that was on the back of the case). a simple printed fan mount that friction fits the bottom of the motor, attach the fan, and no more overheating X motor...

this is the fan mount I used: http://www.thingiverse.com/thing:128526

that mnight work and i was able to find a but ton of 30mm fans for about 2 pucks a piece

I say might, because I no longer have the original carriage, so my current setup interferes with the rods by about 1/4", but on the original carriage or other designs, it might not.

Because this is a more powerful motor, it doesn't need to work as hard, so it doesn't get as hot as the original.  Therefore the heatsink and fan can be smaller.  I bough a heatsink/fan intended for chipsets, with a total depth of about 5/8", and it works great.

Do  search for that kysan model on ebay, there must be thousands of them.  You could always pay $15 for one and get it in a couple of days from places like Printrbot, or Amazon.
