I used a CPU heatsink similar to those, execpt it was larger, and "created" (John_Lawson sent me the module, and Pseudonomen sent me the heat sink) a Blu-Ray labby. The only problem is that I didn't have the cash to buy the epoxy, so I used aluminum foil. And even though it's a low current (Non-Adjustable Rkstr @ 86mA), I could probably leave it running for days and days.
