Question no visable leaks but runs higher temps?

I bought my 98 5.2 last june. The temp gauge always held at what would be about 180-190 range, until the intake gasket blew. I have fixed the intake gasket, new heater core, 180 thermostat, flushed the entire system. The water pump is a year old as well as the radiator.
As the weather warms up, I have noticed that the truck wil run somewhere around 200-210 on days that the high is in the 80's. The coolant is never low and there are no visable leaks.
I was looking at the fan and wondered if I needed to try to find a better aftermarket fan? is it possible that I have the mix of water/anifreeze off and that is causing this problem?

I don't think it's the fan, the fan is used when you're idling. But an E-Fan will help free up some HP about 3 HP depends. It could be anything, but yes a poor mixture can cause the engine to run hotter because alcohol is heavier then water so it doesn't carry as much heat so if you have to much alcohol in the mixture then yea, they recommend 50/50 and so do I, however with aluminum radiators I do 30/70 for more protection.

I would take a look at the temp sensor, they are prone to failure. Mine for example use to read like 145 and I went ahead took the old temp probe out and the plastic was melted, when I poped the new one in the temp rear around 200-210 (195 temp stat).

When you took the intake manifold off did you by chance check the thermostat, it might be defective or something.

I replaced the thermostat prior to the intake gasket. Replaced all hoses as well. But, from experince back when I had my Chevelle, I know you can get a bad one right out of the box.
on the mixture, is that 30 water to 70 coolant? Or the other way around?
I just replaced the temp sonsor on my wife's 08 camry but didn't think about our trucks having one. Where is that located?

I do a 30% Distilled water and 70% Conventional green anti-freeze. I would do straight 50/50 mix for cooling efficiency however I use a concentrated amount of anti-freeze for the protection, I have so many metals in my system, cooler heater core, iron block and heads, aluminum radiator, galvanized steel core plugs. I also watch the pH balance, I try to keep my around 11 and I do a periodic voltage check as well to assure their isn't advanced electrolysis occuring.

Anyway's the temperature sensor, the truck has one how else is their a temp gauge on the dash? The temp sensor is located next to the thermostat, some trucks have two one for the gauge the other for the ECM, if you have two then the one closet to the thermostat is the gauge it should be a 1 pin and the other which is a two pin is for the ECM.
