I think we're splitting hairs here... and, like anything else, depends on usage. Where I'm at, it's Hot. Then, it gets Hotter. If Ya Have the Airflow, that helps. The entire point of having Cooling Fins on a Radiator, is to Dissipate the Heat.... not disagreement, but when, Ambient Temps, are wacked, sometimes letting the Rad do its Thang, is pretty damn important... now, going back to Airflow. I was metal framing, and hanging board, with a Vietnam Veteran, for some Years. Good Personal Friend. The fan blew off his F-150, trashed the radiator, out by St. Augustine, I was in Middleburg. Over an hour away. I took him a Radiator, plugged it in, NO FAN. yes it was Wintertime in N FL, And Yes, I asked Dennis to roll about 50 ( NO One Told Dennis ****!) Never overheating on the way back. We may have missed a TCD once or so...
