So before you go like huh wait a minute, didn't Ryzen have a soldered heat spreader on the die that cannot be removed? Yes, you are right, but of course, you can melt the Indium solderm as when it reaches 175 Degrees C, you can delid.

It is, of course, der8auer who performed the procedure and produced a funky video about it. He really wanted to see if there were any benefits to delidding one of AMD’s latest Pinnacle Ridge chips. His curiosity did not kill the cat and the processor survived the procedure.

When you check the video you'll notice a Ryzen 5 2600 being decapitated, the man used a slightly altered Delid-Die-Mate 2, he heated up the heatspreader to roughly 175 degrees Celcius, the Indium melts and whoop, the heatspreader can come off. Let me just reiterate that it is a seriously risky procedure, as you can easily damage the upper layer of the processor die due to the heat.

Once he finished up cleaning the CPU he replaced the Indium solder with his preferred liquid metal material (TIM), and then some testing is in place.

An interesting observation is that the die is similar in size towards the 14nm original Ryzen, compared to the 12nm Zen+ die size that is. Likely AMD wanted to use the same package and made things fit.

Anyway, we've always claimed that soldered CPUs cool the best, and his tests show that is a real thing. He achieved merely a marginal better temperature as the Ryzen 5 2600 (fitted with NZXT Kraken X62 CPU cooler) running at 4.1GHz and 1.35V, ran Cinebench R15 and peaked at 60 degrees – that shy 4 degrees in difference compared to the stock processor that is soldered. So the end result is a proc that runs 4 degrees C colder. 

Good stuff to see tested, and yeah he agrees. It probably isn't worth it delidding Ryzen ;-)
