Going to try this myself, got a serial which is under warranty bought in 2017. Do I just register the serial and contact support and  do what mothered suggested and say they were admitting a loud sound i.e something relating to health and safety.

Good to hear man, can't wait to hear about it. Just start a chat with them, then they will create a case from there. No need to register anywhere.
Regarding the reason/method, you should definetly follow @mothered advice previously in the thread.
