So I lapped my E6300 and Scythe Ninja...

Hi all I had always suffered from high temps with my E6300 and Ninja so decided to lap them both using a kit I had lying around.
In the end my IHS turned out to be convex and the Ninja concave...

Idle temps @3.15ghz used to be 50-60degrees, load was 75!
Since lapping it idles at 35 degrees and load is 52degrees max so well happy it was all worth it

Paste is AS5, i've never seen cure-in temp drops but here's hoping...

Pics:
400-grit took me the longest and got used the most, probs took an hr to get rid of the nickel

Some 800-grit passes gave me this reflection of the chopping board

Hello croc; on 2000-2500 grit by now

Straight enough for me!

The ninja didn't require too much work but it wasn't flat...

after a short while on finer grits we get this, the happy couple:

last one! Proud of my first lap

Now if only teh ladiez knew...

thats a pretty good temp drop

Very good, tempted to do this to mine to see if I can improve on my water temps.

Currently idle at around 28 - 30 and load of 40 - 42, for the sake of a couple of quid for the paper I may do this when I come to sort my kink in the loop out.

Good result.

Thanks guys, GinG it wasn't as 'hard' as I thought really, just take your time and apply even pressure through the middle of the CPU I reckon...
Just maybe get a few more sheets of 400 from an autoshop

As for HSF's you gotta make sure it doesn't jump around...

I got a good 10-15C reduction on mine when I did it - tho IMO I didn't get anything like as good finish as you got

even the watercooling setup saw some benefit tho not as much as air - 2-3C lower idle and 5C lower load.

Think i'll lap on all my setups from now on, after I establish the cpu's are working first ofc

Nice job, i lapped both my cpu and TRUE black a while back and it also gave me a nice drop in temps, my first attempt at 3.8ghz resulted in temps of 80-80-71-71, after lapping and 2 better fans on the cooler i was getting 68-68-62-62.

I'm gonna have to this with my E2160 and Freezer 7 Pro. Maybe also worth getting a TRUE when I do it

Do you guys think that a reasonable proportion of the cooling effect comes form being extra careful with the thermal paste afterwards?

if one was concave and one convex wouldn't they have fitted perfectly.

Sayso only if you engineered parts to fit like a jigsaw, otherwise there will be poor contact all over the shop regardless
