Rbreb13 Posted September 14, 2002 Report Share Posted September 14, 2002 These are some of the things I have found over the years. Hope these can help if you need them.

jsgolfman Posted September 16, 2002 Report Share Posted September 16, 2002 Great links, man. I haven't had to do this yet with the MCXC, but you never know when it will come in handy. Quote Link to comment Share on other sites More sharing options...
Bruceleeon Posted September 16, 2002 Report Share Posted September 16, 2002 I have read before that lapping actually has an adverse effect... if you think about this from the point of physics it makes sense...Those little peaks and valleys on the bottom of the heatsink add to the overal surface area of the heatsink... Using thermal goop would fill some of these but it would aslo transfer heat through these.. Lapping in this respect, by decreasing surface area, could actually hinder the cooling properties of your heatsink!! Quote Link to comment Share on other sites More sharing options...

You just don't want a mirror finish, just close to it. I've done a little testing on my own and lapping does improve performance. The main reason for lapping is not for a smooth surface, but for a FLAT surface! Quote Link to comment Share on other sites More sharing options...
jsgolfman Posted September 16, 2002 Report Share Posted September 16, 2002 Flat being a relative term. Flat to the naked eye, that is. No matter how much you sand it, it will still have microscopic valleys to fill. Quote Link to comment Share on other sites More sharing options...
JimBowy Posted August 23, 2003 Report Share Posted August 23, 2003 I just lapped my Volcano 7 not to long ago. But, I didnt go in any circular motion at all. I want back and forth across the entire HS. Do you guys think this is alright? I was very cautious to evenly sand the entire thing. I hate to have to do do it all again.

Should be alright just keep an eye on temps for the first few days. I always throw an engineers square on mine to check it. But not everybody owns a $50 straght edge. :roll: Quote Link to comment Share on other sites More sharing options...
jsgolfman Posted August 23, 2003 Report Share Posted August 23, 2003 I have an old piece of wood that's pretty straight , is that ok? Quote Link to comment Share on other sites More sharing options...
Bruceleeon Posted August 24, 2003 Report Share Posted August 24, 2003 i always compare mine to straight polititcians. Quote Link to comment Share on other sites More sharing options...
