Just finished lapping (30mins) my E2180@1.46v + heatsink (Hyper TX) and got a nice result.

Here are the unlapped idle vs. lapped idle temps



Unlapped Difference #CPU -9C #Core1 -1C #Core2 0C



Lapped Difference #CPU -12C #core1 -4C #Core2 -4C

And the Temps at Load



Unlapped Difference #CPU 24C #Core1 36C #Core2 36C



Lapped Difference #CPU 17C #Core1 29C #Core2 30C

I'm going to get some AS next week which should bring the temps down another couple of C.

(the ref temps for the difference are they system temps)

Thanks.
I don't have a real choice of what Compound to get, it would mean importing it.

I can choose generic white, strange gold (what i am using now) or AS. Just found a place selling it last week, but none in stock till next week

**Update**

I just added some OCZ Freeze and these are the new results (differences between average and system)

Idle Temps



Differences - #CPU -13C #Core1 -15C #Core2 -15C

Load Temps



Differences - #CPU 6C #Core1 14C #Core2 15C

However, i believe the load temps should be calculated from max as after only 3-4mins of stress testing the av. temps were still going up.

So here are the results with max temps (at 100% Load).

Unlapped

#CPU 21C #Core1 36C #Core2 33C

Lapped

#CPU 17C #Core1 29C #Core2 30C

Lapped with OCZ Freeze

#CPU 11C #Core1 25C #Core2 26C

Note - When i put the OCZ freeze on the chip, it was clocked at 3.5GHz (other tests were only 3.15GHz. Because of VDroop the difference between voltages is 0.03v (av Voltage at load) I'm sure the voltage difference account for some of the difference, but the extra 100mhz should make-up that difference.

Anyway. For less than $10 i got a Temp drop (at load) of #CPU-10C #Core1-11C #Core2-7C
Not bad for a couple of hours work and a few bucks :bounce:
 
Nice work! lol, you, me, and a few others are some of the few ppl who still lapp HSF/CPU. Just a bit of info, instead of water for lapping try some shaving cream ( I'm not kidding here), I have found out that shaving cream works better than water (gives it a smoother finish).

lol i didnt bother assembling mine before lapping - i lapped my e520 straight away. ridiculously concave too, a massive cave right in the middle lol... took hours and hours of 240 grit sandpaper, no joke.
