Question Radiator fan stuck on after heads/cam

After i did a heads, cam, fbo setup on my 6th gen camaro ss the fan immedietly kicks on low and then a few seconds later ramps up to full blast even on cold start. AC is off. Ive tried switching the relay, unplugging everything plugging it back in, disconnecting the battery nothing seems to fix it. I know its not tune related because it started doing it even before it was tuned. (I ran the car after I finished the job at idle just to make sure all was well.) I am running a katech 174 thermostat but that was tuned in with hp tuners. Also it does it immediately way before the thermostat even opens. Any suggestions would be greatly appreciated!!!

No CEL. But I figured it out, turns out the condenser pressure sensor wasn't fully connected.

Good to know, I’m sure this will happen to someone else eventually.

Glad that you got it figured out.

I had a feeling there was something external causing the fans to run.
