Great job on your rivit tutorial! As far as I can tell from your pics you did an excellent job lapping your CPU.

I was going to purchase those Artic Cooling RC memory heatsinks for my ram but decided against it. Regular paint can act as an insulator and may noticeably affect temps. However, having them anodized can minimize the hit.

But painted heatsinks is better than none at all.

If you haven't seen this before, Tremeloes has a system displayed on MDPC with what appears to be these same heatsinks in white.

Keep up the great work. I'll be looking forward to more.
