Lapped my 4600X2

post #1 of 9
Thread Starter 
I once tried lapping my proc, but I only had 2000+ grit sandpaper, so it made it really hard to start out... Just recently I went back in for another shot, and had some pretty sweet results.

I used 220. 320, 400, 600, 1500, 2000, 2500, and some 3000 my dad found for me. My idle temps remained about the same, maybe ~1C off. That was depressing at first...

However, I decided it may just be the fact that the TIM hadn't worn in yet, so I let F@H run for a day or so. I'm sitting at 40C at full load while I'm typing this, and it has been going strong for about 2 days. Case ambient temperature is 31C and outside ambient temp is 27C, it's pretty warm.

I'm really stoked, that's about a ~8C drop in temps at full load for me, it was also great to fix my old lapping attempt

Thanks to all the guides and tips I saw from people in general!!

EDIT

Forgot to include my OC/vcore. I'm running it at 2685 right now to be safe, on a 1.39vcore. 1.35 stock. Hey, it's a Manchester core, it needs more volts than necessary to remain stable because it sucks.

Paper, congrats!

You didn't happen to take any pictures did you? Most of the time you won't notice a difference during idle. Full load is typically the major difference you'll see with a lap job. Did you go all the way up to 3000 grit? Did you use any polish for a nice finishing shine?

Great job

I didn't take pictures, because for now I have no way to get them into my computer... My cord broke somehow a little while back Even my vacation pictures (to the bahamas ) are still on it.

I didn't use polish, as I am too lazy to buy any, and I had also read that it can fill in the tiny holes that still may be leftover, which is the TIM's job, not polish..

I didn't use the 2-3k grit for veyr long, because it looked good as it was. But yes, I did go to 3000 grit. My father used to work in a paper mill, and he has an unreal amount of random supplies in his basement. TONS of sandpaper, screw threading things, clamps galore, gas masks, fire protection suits... I guess it's not weird stuff, lots of people have it, but he has a lot of it... I'm using some lame coolermaster crap, but I have some Arctic Silver 5 (and an 8800GT ) coming in the mail in the next few days. So I will probably reapply the TIM and if I can get a hold of another camera will gladly take some glory shots

Paper, that would be the obvious assumption but after cleaning the base with 90% isopropyl alcohol I doubt any of that residue is left over...but of course everyone has their own opinion

I mean the polish fills int he holes, right? I don't know how to polish it using polishing fluids or whatever, so I may just be blowing steam... lol.

I was under the impression that lapping was also constituted as polishing? I used 91% alc, so I think it definitely removed all of the old school TIM.

Nice results! Everyone says that the Intel IHS' are always in much worse shape than the AMD's, but my 4800, and your 4600 obviously begged to differ

Paper, lapping and polishing are a bit different. Lapping is when two surfaces are rubbed together (ie. sand paper and the base). Lapping is very useful when the surface is convex/concave. Polishing usually creates a smooth shiny/mirror like finish but doesn't actually create a "flat" finish.

Hope that makes sense

When the term 'letting the TIM set in' is used, it does not mean 'run at a hot temperature for a while'

What people say [or what is meant to be said] is that the TIM sets in with repeated highs and lows in temperature so that it expands and contracts filling all the tiny tiny gaps over time, then to a point where no more gaps will be filled - this is when the TIM has 'set'

Just thought that would be useful knowledge
