Hi fellas! I am from Toronto. I run a computer store. I have sales of various hardware components. I want to know if it is okay to get heat sink's manufactured from a local manufacturer. I have been thinking about this for quiet some time. There is this manufacturer in Toronto who manufactures precision metal products. It is given on their website that they manufacture heat sinks http://www.bayviewmetals.com/metal-fabrication/precision-sheet-metal/. I want to know what are the things that should be take care of while manufacturing heat sink's for gaming pc's. What kind of fans are the best for such cooling fans. I hope someone can help me with this.
