Lapping = No difference

I had a go at lapping today, one core on my Q6600 was always a little hotter than the others.

My dad has a flat plate that I used clamped into a vice.

Spent quite a few hours on it, got it nice and flat and finished it off with 1500 grit.

Result - exactly the same as before, not even a reduction in temps at all

Oh well it was fun all the same.

I knew my cooler was fairly flat, the CPU seemed a little concave.

Anyone else ever lapped and founnd temps the same after?

Is there much difference in temps between the 4 cores?

Nick1881 · 12 Jan 2008 at 18:54

Right now

Core 1 - 44-45
Core 2 - 37-38
Core 3 - 37-38
Core 4 - 39

Actually I think it may have took a chunk off the load temps, before that toasty core 1 was hitting 72, now its at 69

Orthos load temps

Core 1 - 69-70
Core 2 - 68
Core 3 - 68
Core 4 - 69-70

A tweak of my fans and they drop to 60

If your useing AC5 it can take a week or two for it work fully

Point taken, I am comparing fresh AS5 to AS5 that had over a week to settle.

Still my hope was to fix core 1, though under load it isnt far out.

Do your heatsink next

I think thats pretty normal for Quads.

My 2nd core is always ~5 degrees hotter than the other 3

Yeh my first core is always 4-5 degrees hotter than the rest.

homi-sid-al · 12 Jan 2008 at 19:55

strangely my first 3 cores stay the same and the fourth is a degree or 2 cooler at idle.

As said before, I'd have a go at the heatsink, take a little bit off the base of that might make a difference.

Sorry forgot to say I already did the heatsink at the same time, it was already pretty flat just Scythe put a fairly rough finish on it so now its nice and smooth.
