I have the exact issue. Ordered last of November as a Christmas gift. Received on 12-Dec, opened/built on 25-Dec. Small prints started ok, now having clicking/popping with all prints. Primarily larger ones. Tried all suggestions in this thread, still not printing perfectly. Exposing the mainboard to outside air and adding additional fans has helped, but not eliminated layer shift. In fact, I ran a "benchy" last night with a layer shift at the top.

I hope Creality finds a solution to this issue. It is very troubling to buy a new printer and it simply does not work.
