HELP - 2014 GM Truck Chevy Silverado

Just installed the 87 octane tune on a 2014 Silverado Z71 5.3L.
Install went smooth for the ECM (87 octane) and TCM (firm shift).

After installing, I started the truck and the electric fans went immediately to full speed.

I didn't have time to make any tweaks or try other tunes.

Is there anything I can do to avoid this?

Going to try some more tomorrow.
