Disconnecting the CPU IHS
Disconnecting the CPU IHS
I observed a technician disassembling a computer on another channel. At the 54-second mark, he took out the integrated heat spreader, replaced it with something else, and then reassembled it. The reason for this change isn’t clear from the clip, but it might be to test or adjust cooling performance.
The soft solder was taken off to add a finer coat of liquid metal, which raises temperatures but also introduces some risks.
Not sure why they re-use the IHS plate even with liquid metal. The temp difference between solder and LM is negligible as they are both very similar W/mk. The best results are always running naked die as long as the cooling solution can move the BTU quick enough. Here's a i7 930 I literally just de-lidded. The solder was only "scraped" off I haven't even sanded the core yet.
