Yep, fans are off at speed. I’ve never run with them disconnected, but it’s obvious when they’re on. I can see it on the fan controller and see the difference on the voltmeter. Plus they only come on at the programmed temperature so if the engine is cooler than that they’re off.
I’ve never had an issue with cooling at speed, the fans never come on if I’m doing more than 25mph for more than a few blocks.
