I just unboxed my Ryzen 5 1600x and just learned it wasn't delivered with a heatsink. Let me quote the manual : « 2. Use only the heatsink/fan provided. Use of any other heatsink/fan will void the warranty. 3. Never use the processor without the heatsink/fan installed. » So according to 3. I can't use the proc and according to 2. I won't ever be able to use the warranty... (I ofc understand it's a global manual for every procs, however can't AMD void my warranty with this clause?)
2 is a misprint and was corrected by AMD to read that as long as the third party heatsink is rated for at least the TDP of the processor it won't affect the warranty. As for not having a heatsink in it, it was supposed to and you either got a returned processor with a missing heatsink, or somehow it didn't get put in the box in the factory. Best bet is to return the processor for a replacement.
