If they?re soldered, I don?t see the point in delidding, if anything the heatspreader gives a greater area for heat transfer. As for the IHS having some heat capacitance, it makes sense intuitively, especially since it appears (in the videos) to be lined with copper. Mind you I?m just a spectator here, I don?t mod anything.

I have GA-890GPA-UD3H and GA-Z77X-UD5H, both in new condition, and soon I?ll be taking one of my Sabertooths R2.0 out of service, if interested message me.
Using a torch is not needed and dangerous. He should have stopped after 1 min because there was something wrong with the cpu.
The first method I used was the one the german used but it did not work. I stopped after 1 min because the cpu was extremely hot and it wasnt moving at all. Then I decided to try with a simple lighter. After 45-60 seconds it popped up without issue. I did some research and the solder used melts at 140-170 C. The PCB can sustain 220C and more. So there is some " room " to play with, not as dangerous as one might think at first.

Once my phobya liquid arrives I will try it. Liquid metal has really high conductivity, nearly 10 times more than any thermal paste. With only the die to cool down, this might make a huge difference in temperature.
