you'll see i've taken that into account when i post the rest of the pics ...

here's an example which shows the previous curve of the IHS:

Isn't it better to take off that heatspreader, like in the article that was posted here a while ago?

with more recent CPU you run the risk of destroying the core as it has been glued to the IHS.

no **** :/

I didnt think there would be substantial differences between those CPU's... Guess again :p

Luckely I bought it rather cheap second hand (trayed), and I wasnt really satisfied with the temperatures. (that's why I took the risk). Initially, all went well. I've gently put a cutterknife between the heatspreader and the CPU, went all the way around a couple of times, but the damn thing didn't came off. Then, I tried twisting the heatspreader a bit, it didnt move a bit. Then I started carefully using the knife as a lever (hefboom?), and I heard a small crack. Not healthy, so I tested the cpu as it was right away. Dead offcourse ;) Then I took it off with brute force, and yes, the core came off with the spreader. It almost seems soldered to the heatspreader, there's this tin-like substance all around it, I can't even get the damn thing off the heatspreader using a hammer and a screwdriver as a chisel. I'll have to read the manual for my canon A75 if I have a moment, so I can take some clear pictures :)

Anyway, I'm looking for a cheap/fast northwood "C" cpu now ;)
