Lapping heatsink

post #1 of 18
Thread Starter 
I'm gonna take some time to get the rig sorted and leave it for a good few months before even thinking of opening it again. So might as well lap the heatsink.

Thing is though, is there something you can substitute for a plane of glass? I can't seem to find any in the house that are a decent size to work with.

my missus didn't take too kindly to me using the glass from a framed photo of her; but it was a better option than ripping the vanity mirror off the wall!!
I got an 8C drop, though part of that was cause the first time I mounted the HSF I had WAY too much AS5 on. This time round I took the tip of half a grain of rice, spread out right to the edges with a razor blade.

Have fun, definately worth the effort!

It is important to get them smooth and flat. A super high polish is unnecessary, it does not have to shine, the key word here is flat.

Get something perfectly flat like a small plane of glass wrap some sandpaper round it and sand it down.

There's an indepth guide around here somewhere
