There is no speed dependency for fan control. Strictly based on temps vs. fan output %. ECT, EOT, TOT, IAT each have their own table - and highest request wins. What this means is say each input below with respective fan %:
ECT = 60%
EOT = 40%
TOT = 35%
IAT = 0%
Result will be fans driven at 60%.
You can access fan tables with HPT or EFILive.
Don't make mistake in assuming max fan % is only ~90% - so you should raise to 100%. PWM fan controllers have max output at some level <100% (depending on controller). Raising will NOT increase fan output, but can damage fan controller.
BTW- 280 is well within temp limits of synthetic oil, so will present no problems.
