I hate the heat...

The heat of the heatsinks that is. I asked about this a while ago, but I didn't get a very clear respone. Well, it was pretty clear, but I'm not sure my question was completly understood. I learned that scratches will reduce the heat transfer of heat from the chips to the heatsinks. I have two heatsinks, and they had glue and crap on them, so I scratched it off with a knife. I scratched the heatsinks pretty badly too. So, will this matter if I use a good amount of thermal compound? By good I mean don't mean huge amount.

Here's the pics:

if thermal compound gets in the cracks it'll be fine

go to wallmart, pick up and 500 and 1000 grit sandpaper... clean them up and then use some thermal compound. You'll be fine

im guessing thermal compound is what you use to hold the heatsinks on to the chips.....where can i get some.

thermal compound is what you use to make thermal contact between 2 surfaces, what you need to attach the heatsink to a surface such as a chip, is thermal adhesive, http://newegg.com

I have found that one of the best ways to cool the n64 board, is just to modify the original heatplate, also the later revisions of the n64 produce less heat, since they consume slightly less power

if you are going to sand the sinks (not that bad an idea), then lay the sandpaper down rough-side-up on something very flat, and rub the heatsink on it. the idea here is that we want to keep the mating surface perfectly flat, if you make it convex or concave you will just make matters worse.

OK, thanks for the info. Now to home depot for some sand paper...

and yeah. get the highest grit you can find even, and maybe steel wool them at the finish. you want to be able to see your reflection in it.

haha. i dont know if it would actually reflect that well... but its gotta be reeeallly smooth. or youre just going backwards (they arent that bad right now... you could probably just use them)
