As is typically the case when der8auer puts processors on the operating table, he coaxed the processor's heat spreader up to a temperature of around 180 degrees, after which he was able to pop the lid off. A temperature range of 170 to 180 degrees is where Indium melts, which is the solder that AMD uses on its processors.
Once he was able to scrape off the Indium solder, he decided to replace it with a high-performance liquid metal thermal interface material. Now with the modifications complete on his Ryzen 5 2600, der8auer affixed a Kraken X62 CPU cooler and jacked the core up to 4.1GHz at 1.35V. For reference, the standard Ryzen 5 2600 has a base clock of 3.4GHz.
Running Cinebench R15, the stock Ryzen 5 2600 measured 64 degrees Celsius at 4.1GHz with the Kraken X62. In delidded form, the processor registered 60 degrees. While 4 degrees is notable, der8auer concedes that your average enthusiast shouldn't risk potentially destroying their processor for a few measly degrees. However, if you’re brave enough to attempt this procedure, it can also be used on both Ryzen 5 and Ryzen 7 2000 series processors.
