DonkeyOatie :
That is a decent usage and a good temperature. That's an overkill system for CS:GO. What FPS do you get? What is your PSU and motherboard?
Intel chips are generally engineered for higher temperatures than AMD at the moment. Anything 60C or less is nothing to worry about at all (unless it is your idle, which needs to be near 30C)
My psu is Corsair CX Series™ CX750 - 750 Watt 80 PLUS
Motherboard is MSI Z170A KRAIT GAMING R6 SIEGE
My average fps is 200-300
