QIDI Q1 Pro electronics air flow can be improved, this mod was created to add 80mm 5V, you can use 24V using parallel power splitter using the stock fan, fan holder.
If you use 5v, much quieter and enough air flow, you can connect the 5V power to this connection from the mainboard:


You need to reallocate the stock 40mm fan to another position, I suggest use this mod https://www.printables.com/model/811634-qidi-q1-pro-internal-fan-mount-with-usb-cable-spac
We suggest, a lot, to print this another mod https://www.printables.com/model/861717-qidi-q1-pro-activated-carbon-box to assure the chamber filter fan do not insert heat on electronics chamber
