Cooling temp question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I used an IR thermometer to check the engine in difference places why it is running. I had my truck running for about 10 minutes the other day and my radiator barely got upto 100 degrees on the return side and about 80 degrees on the supply side. I measured the point at the manifold temp sensor and got about 130, which is what my gauges read. If its just their idling will by cooling fans ever turn on? Does this sound right to anyone else out there running electric fans with four core radiator?
