Show us your IHS with a large dollop of lapping

I have been reading a thread or 2 where the members are lapping their IHS (Integrated heat spreader)

Why?

Some of the IHS are concave, they have a distinct ridge, this is creating the need for a large amount of thermal compound or the need to get your fine wet n dry sand papers out and start lapping. This is happening across the Amd range so show us your IHS :p

Lapping Guide (this guide applies to IHS's also, but be very carefull with the Cpu pins)

Lucky me nice flat edges on the X2 IHS no real problems here.

Not the story for my old Amd64 4000, obvious imperfections

I didn't lapp my cpu IHS, I lapped my Scythe Ninja instead since the X2 I got has a good IHS :)

danke

i recently took apart a 10 year old pc, take a look at the ancient chip

 
Serviced/took care of a roomfull of those VERY MIIs yrs ago, some had IBM badges on em, all passively cooled in compaq machines.. god it was so hot in there.
 
Hah all the compaqs gave between 73 and 74FSB, love that sis 5598 (i think)chipset :D a mate paid almost 2000 in 98 for a machine with a PR333 in it from Time PC, had a good laugh i did.

Or keeps one core hotter than the other? :D

Both cores on my cpu are at different temps even though the waterblock is screwed down evenly. Strange thing is the core that fails first is the cooler of the two
 
Om my 165 one core was 10C hotter on average, always bombed out first too, removed and i got equalish temps, avg 5c lower and o'ced 100mhz more on the same vcore.

How can you tell if one core is hotter than the other?

I thought there was only one thermal probe.

Each core must have its own sensor, I know Everest Ultimate displays 3 sensors results I take it 2 are core temps and one is the socket temp sensor.
