Do people still lap?

ive been out of the game for awhile, and was wondering if people still lap the HS/WB and CPU? I have a 8320 and kraken X41 and was wondering if it's worth it
 
Depends on how well your processor and heat sink mount. Do a pressure test and decide if it'll be an improvement.
 
Some people still do, but it's quite a bit of work for only a very small gain. I think de-lidding has become the new lapping.
 
Ah, I remember lapping. Getting down to that mirror finish, always felt like quite the accomplishment. Nowadays, most are lapped already.
 
I lapped the heatspreader on my Xeon X5670. Didn't do a great job cause I got bored after a while, but I did at least get down to the copper on the heatspreader. No point delidding my chip since the heatspreader is soldered on. I got like a 1C improvement in temperatures...barely noticeable and well within the margin of error that you see with just varying the application method.

Might give it another go and try and finish what I started in a few weeks when I take everything apart to put in custom cables and tidy it all up. I doubt I'll see much improvement, but why not.

An electric orbital sander with 400 grit wet sandpaper drops the time from a few hours to about 10-15 minutes to get it flat. You just have to rinse off the shavings quite often to keep the paper from getting clogged.

You just hold the orbital sander upside down so the sandpaper is facing towards the ceiling and move the CPU IHS around on it.

Yeah, the very corners get lapped down a bit more than the rest, but it doesn't make one lick of difference.

Then you can polish it with higher grit if you want to, but the grit when using the orbital sander gets finer as it wears down.

I've used this method on multiple CPUs and Heatsinks and have never once had a bad result.

Brilliant! I can't believe I didn't think of that. Just need to see if I have any higher grit paper for my sander.

I lapped my old 8320. Dropped about 5C.
