    Just use 2-3mm aluminium u-bar. Stack it in rows. It's very cheap compared to commercial heat sinks and works perfectly.

    if you get aluminum bars which are thick enough you can passive cool them.. meaning that you wont need fans.. other wise try PC fans they are quite cheap and move a lot of air. also work on 12V

    I got some from mantech. Online ordering and next day delivery in joburg. I compared the price with u-bar from builders warehouse and it worked out cheaper, easier and I suspect ore efficient.
