Lapping Thermalright SI-128SE!
I've never been pleased with the base on my Thermalright SI-128SE. Its quite convex and bulges off-center to make matters worse. I finally decided to break out the sandpaper and get to work. I've been at it for nearly an hour and it is still not flat. It is much better, but there is still quite a bit to go. I'm on my third sheet of 220 grit.
For some before shots, you can take a look at my heatsink roundup from back in December.
This first shot is after about 15 minutes..
This is after almost an hour. The darker looking copper is the problem area. Its incredible how much material has already come off.

I went through four sheets of 220 grit, one sheet of 320, and below is after a quick 600 grit polish--still rough looking.
Finally, some more 600 grit polishing and then a 1500 grit polish for a mirror finish.
Three hours of my life that I'll never get back it was worth it
They should sort this out in the factory imo.
There are other products being released lately with performance in the same league as the U-120-x, and have better base finishes. TR has some great engineering, but their QC has gone down the crapper.
I'm seriously thinking of trying the new Noctua heatsink out for my next air cooling purchase. It's roughly the same price as the U-120-x, but includes a high quality, quiet fan with it.
I'm very pleased with the Noctua NH-U12P. Its a fantastic heatsink, mudd.
