As you all may know, I've been around this computer forum for a while.
However, I'm also a flashaholic, particularly LED's.
Right now I'm working on a project with an LED, and I need heatsinking for it.
It won't need to be portable, ie. a flashlight, so I think I will use a CPU cooler.
The LED will be star mounted on a MCPBC. That link may or may not be the LED I will end up using, but they will all have a similar aluminum base. Note that the largest star size I will be able to find is probably 21.8mm.
Now I already know that I can just use Arctic Silver Alumina thermal epoxy to mount it, but I'm not sure how think I should be aiming for.
I personally think that a dab of normal thermal compound and using a washing+screws to tighten the star onto a heatsink would be more effective. However, I don't have access to any milling equipment that I could use to drill a screw hole into a heatsink, and that sounds troublesome anyway. So I'm wondering if I could find a mounting bracket that would fit for this...
Also, what would be the most effective thermal compound? I thought I remembered hearing one that beats AS5, but that was a while ago and I honestly am not sure if I actually did read that, or if it was just a dream of sorts.
One more thing, a cheap heatsink. I know there are plenty of cheap ones at around $10 - $15, but I really don't know anything about them and I would like it to be somewhat decent. What voltage/amperage would the fan run on?
EDIT:This sort of heatsink mount might be what I'm looking for...
