Unless I missed it, the only time temps got mentioned was with the GMC. Would be nice to know what temp all of them ran.
Was thinking the same thing. And with the Ram running 5500 rpms most of the way up, I have a hard time believing it's temps weren't creeping towards hot.
Heat comes from fuel not rpms. (On any particular engine the higher it revs the more fuel it can burn so it will produce its most heat around the rpm that it makes its most HP) But on this test the Ram used the least amount of fuel. The 5.7 is a smaller engine than the Chevy but if it pumped as much or more air through in that same time, on account of its higher rpm, there would be more cooling being accomplished through the exhaust and less heat going into the cooling system. If the fan was able to run faster on the Ram due to those high rpms it is conceivable that the Ram would run cooler than the Chevy. Obviously the size and efficiency of the cooling system in each truck is what ultimately determines its ability to stay cool.
