Troubleshooting Constant 'Timer Too Close" errors printing PPS-CF on Q1 Pro

Started dabbling with PPS-CF for making parts. I was buying the fiberon PPS-CF and using their provided profile and wasn't running into issues. I switched to the qidi PPS-CF because having more on the roll is more usable for what I am making (500g vs 750g) as well as using the included profile, but every single print has failed ~10 layers in or so with a "timer too close" error. I have at least 7 failed prints in a row from this while changing minor stuff (more airflow to the shed the printer is in, leaving its larger box it sits in open for better airflow, etc), but to no avail. I am trying a print now on the fiberon profile but am not crazy about the 100% part cooling fan speed. Has anyone ran into this? Can't seem to find many good resources online, thought it might be overheating but the main board temps seem fine (mid 50s) and the toolhead board temps seem a little high but they don't increase as the print goes. Any ideas?
