i had this happen to me the first time i changed a cooler for a ryzen and it freaked me out. never seen it before so it caught me completely off guard. the cpu was actually warm since it had been running for a long time before the swap. i had actually run prime 95 to test temps to see what the new cooler brought to the system. not saying warming it up never works, but it did not for me.
since then, i have been releasing the cpu from the mobo and pulling it off as one and then removing the cpu from the heatsink. i don't trust it to not damage something if it happens again. like said above, then some dental floss or thin fishing line works great for breaking the seal. if i run across one of these to buy, i might actually try it out to see how it goes. but it better be a solid chunk of metal so the chip does not move around at all. if not, then it might not be any better than not having it.
