I have the ASUS ROG Maximus IX Hero motherboard. Idle temperature is about 40-45 degrees Celsius. When rendering a video it goes up to around 75-80 degrees, just wondering if that's an alright temp for it to be or should I get more case fans? I only have one 120mm fan in the back and I'm using a Cooler Master TX3 EVO cooler on my cpu and even my cpu is around 39 degrees idle / 77 on full load, not quite as high as my motherboard. What do you guys think?
