Just in case anyone finds this interesting. The last transistor near the die on the 4670k came off along with the lid - seems the original glue took it with it. I'm referring to the one closes to the edge - at the same level as the top part of the die.

The cpu is working perfectly fine at 4.7, with normal stability. I was sure I killed it.. my delid only nettet 7 celcius difference. But this is with a crappy thermalright white paste.
