We mentioned in our reviews that you should not delid AMD Ryzen processors for the sheer fact that even the heatspreader has sensors and that it is soldered. Next to that AMD did the cooling part rather well so the benefits of a lower temperatures versus the risk of bricking that processor might not be worth it.

Well, that thesis has been confirmed, pro-overclocker der8auer took a Ryzen 7 1700 (well actually multiple of them) and delidded Ryzen 7 to see what was hiding behind the Integrated Heatspreader (IHS).  It took der8auer multiple attemempts to get a succesful delidded processor. To be more precise, it actually it took him three processors hence we can already conclude that the process is very risky.
  

 
In the end he succeeded though, in the photos below (clock thumbnails) you can see a Ryzen 7 1700 CPU delidded. You will notice a solder layer that ties directly to the IHS.  Looking att he processor you can see multiple capacitors, all nicely covered by some sort of silicone protective layer, so AMD certainly went all the way here.

So what weas the end-reult delidding and cooling ? Well, der8auer shows it in a video, but the he achieved a drop of 2 degrees C lower on overall temperatures with a cooler sitting directly on top of the processor die. In short, and what we have been saying. Please do not delid the processor guys, chances are high you'll damage it and the temperature drop certainly doiesn't justify you bricking the processor or loosing warranty.
