I lapped my Q6600 - Tell me if it looks right... because it performs right.

600-->1000-->1500-->2000

Got lazy at the end; the scratches aren't exactly straight but w/e. My question is; notice on the edge of the chip it's sloped down. In other lap pictures it looks like they sanded all the way down to that also. Do I need to sand more off?

Most people take about that much off, they usually leave that slopped part untouched, but if it works well I would keep it that way.

Did you lap the cooler too ?


did you lap it with the cpu in the socket ?

The point of lapping is to make the surface of your processor even, not to sand it to a mirror finish. Best way to check if you did it right is to take a straight edge and rest it on the processor. Shine a flashlight on the straight edge in the dark. If light peeks through, its not even and needs more lapping. Make sure the straight edge is upright when you do this. Usually the edges are the biggest culprit

So from this image, I cannot tell if you've done it right.

We can't tell if it looks right. You have to take a razor and put it on IHS. Shine a light through it and if you see any or if it's too concave or convex then try again.

Personally I would have gone 400-800-1000-1200-1500.

I taped some sand paper to my glass table in my living room and ran the chip up and down.

I lapped my heatsink as well but it's a push pin design crap heatsink so I wasn't able to lay it flat, I free-hand lapped that. I didn't care too much as I'm buying a NH-D14 soon.

It dropped my temps from ~85C max to ~75C max(Still running Prime95 from 30 minutes ago), so it's definitely effective.

I only get the 10C drop when I use the dot TIM apply method. When I smear it flat with my finger and a bag I get only about a 3C drop because the heatsink is either not laying flat on it or there's not enough pressure against the chip because it's push pin and not a screw system. When I take the heatsink off after smearing the TIM it's only contacting a rectangle in the middle of the chip. (This is actually why I decided to lap it.)

...and yes I know about the point of lapping, I just like the finish as a bonus.

When I get my Noctua I will smear a thin coat of TIM and mount the heatsink then take it off again to see the contact. If it's still doing that stupid rectangle thing in the center I will know it's the chip and I will re-lap it. (Pretty sure it's not the chip though.)

Edit: Just some schtuff.

I'm no expert on the matter, but that looks fine to me. The majority of heat will be centered on the heat spreader, so those edges aren't really going to matter.

Throw an angled shot with some mirror finish action up!

This is bad!! Do this with your cpu at multi angles and in different spots. There should be no light getting through. Use a brand new razor.

I did this to start out with but it wasn't accurate because my razer was 2 years old and rusty. lachen.gif I think I need to buy one.

Also can anyone tell me why the hell my first two cores are always more than the last 2. From my understanding there are two different objects under this IHS like shown here:

101813d1237343701-cpu-lapping-resized.jpg

And each is independent and has it's own temperature range more or less, and in my case one just runs hotter than the other?

Just be careful when you do it. When I was trying to decide if my cooler needed lapping, I did the razor test and pressed down too hard. Left a nice little cut in the copper.
