post #9571 of 12377
Not sure of the actual measurements, but my 8320 was the same. High edges and slightly concave everywhere besides the where the core is.

I kept lapping till the cpu was a solid copper though. Took it to 2500 grit, and then used some polishing compound to buff it to a perfect mirror.

Dropped my full load temps by 5-7c

Huge enough to be ignored.

Thing is, the CPU and the cooler were mounted off due to those high edges and lumps.

5-7C with what cooler? Or waterblock? Was the cooler or block lapped too? 5-7C is pretty tempting. Most of the lap jobs I've seen in the last 2 years people say around a 2-3C improvement.

this was awhile back, but temp 2 is cpu. Take note of the ambient temp in temp 1, 2c difference. Its a water block, I lapped both the cpu and the water block. I would retest with the new setup, but would need a different cpu to show the results.

That is dependent on each set-up.

On mine for example, pre-lap, I can't go further than 1. 488 Volts as I'm already hitting the 70 degrees core wall.
After lap, I have shoot up to 1.520 Volts on my core without hitting 70 on the cores.

That is due to my CPU being concave. And my cooler being with high edges and slightly elevated center contour.

If you have a flat cooler, and a concave CPU, the issue will be less and the temp savings will be less.

Good temps!!!
post #9576 of 12377
Nice result thumb.gif

So if i come correct its worthy to lap my CPU, 5-7c drop in temps under load is huge if you ask me.

Sadly we cannot remove the IHS since its soldered rolleyes.gif

There's really no need to remove the IHS. Soldered IHS were very closed to being bare-die compared to Intel's IHS piece of snot TIM. biggrin.gif

Also note that the gains seems very negligible if you already have a cool system. So comparing the temps clock to clock and voltage to voltage might not indicate the real headroom gains.

One example is the temp i got at 4.5 GHz 1.38+ Core V.

Before lapping, I was bordering at high 40s but under 50. (Being my fail-safe profile)
After lap, I didn't get lower than 45 at same settings. (Again, being my fail-safe.... doh.gif )

But the real gain was hiding somewhere. biggrin.gif

Maybe one day I'll lap a CPU, been in the back of my mind past 2+ years. Maybe my old x4 955 just for the heck of it. Not sure it's worth it on this 8350 and EK Supremacy block.

Okay, i was curious because like you said Intel has some very cheap applied IHS i seen on the net and there are some vids of it too.

But honestly, i am curious about my temps, i will look at it tomorrow and see how my IHS on the CPU is, if its bad i going to lap it.

Also the CPU block of my h100i looks like it could use a little touch up so if i can get some good sanding paper i will lap it.

One quick way to check if the mating for the CPU and cooler is by pressing while twisting the cooler into the CPU and see if you have some scratches on either of them..

Scratches will indicate those high edges if they are apparent.
