If you mean the sound of the fan, then yes. it happens to everybody. It is supposed to. The fan normally slips. As the cooling demand is increased the fan engages more and more. When you hear it howl, it means the fan is more engaged and pulling more air through the radiator. It's how the clutch system functions. It is noisy for sure. Your choice is to remove the fan and have peace and quiet, or let the fan function properly. ha!
Or you can purchase and install electric fans.
If you are concerned about the temp based on gauge position, I suggest getting a gauge to read the physical temp. Ultragauge and Scangauge are two affordable gauges. If you don't want to do that, get an infrared tool and check the radiator temp. I don't know what you mean by "between 1/2 and 3/4". But if it is in that range I'd say it should be. That is a huge difference in temperature. Your truck will probably run up to 215 degrees. Mine idling on a 110 degree day for 5 minutes resulted in 212. It bounced around a little until 2 miles on the highway before it dropped to around 202 then finally about 196. Numerical readings are from my Ultragauge. As a matter of fact, the reason I purchased Ultragauge a few years ago was so I could read water temp.
One of the biggest complaints about this truck, especially as summer comes around is the temperature relative to the gauge needle position. It is 'normal' for the needle to get that high, unlike most any other vehicle.
