DIY Heat Sink

    I just found this idea on another forum and thought I post it here.

    Good idea for people who like to do DIY or who are
    short of $.

    Buy some C-channels at Home-Depot .

    Line them up next to each other and drill holes across C channels then slide a metal rod thru holes and bolt together. Two or Three rods should secure it well enough.

    Not a bad idea plus you can cut to any size you want. Also you can connect some airplane wire to the rods and use it to hang your heatsink.

    Metal Rod goes across -->|_||_||_||_||_||_||_|--> and out this end..attach some washers and screws to secure.

    I didn't know what C-Channels were when I read his post so I did a quick search on C-Channels
    and found these. Clear Anodized Finish C-Channels using 6063-T5 Aluminum. This Metal is used by alot
    of heatsinks makers. There is better out there but I haven't look to see if it exists for C-Channels.

    PS: Give Thanks To seaf0ur from another forum.

    I hadn't seen this - I'm cheap and like to use stuff from the hardware store so it definitely get's my interest. Seems like a decent solution especially if you are pairing with active cooling (I like cheap 120MM 12v case fans personally)
