Hi

Now that is great design, how do you screw onboard heatsink to bigger one?

monkey29 · 3rd April 2007, 02:23 PM

Hi luka,

There are two threaded holes in the heat sink, Similarly, there are two holes on the shell(top), Linking them with two screws.

Hi, nice job!
Where did you source the heatsink case?
Thanks!

Thank you!

I found this heatsink in a Beijing factory.
