ZWO fan replacement & loose circuit board

ZWO fan issue;
Scary issue when my ZWO294MC Pro camera started getting hot and the fan was not working. Even scarier that the circuit board was loose. There are a few videos on how to replace fans in a ZWO camera. I got the fan from a vendor here in the US. ZWO wanted $30 to ship to me from China. I was about to just order one online that matched the dimensions until I found the US vendor. I live in the US.
