I'm currently running a i7-4790k and a MSI GTX 970. I have a Hyper 212X Turbo and have 5 case fans. At idle, my CPU sits around 50C and my GPU is at 59C. Even at idle, my GPU runs at 11% fan speed automatically and when I go to run a game like Rocket League, the CPU hits 62C and the GPU hits around 65C. Can anyone tell me why my PC is running so hot even at idle? It has been making my ambient room temperature drastically increase

In all honesty the 212X Turbo is a much worse cooler than the vanilla Hyper 212X. You will also need to mention you full system's specs. list the like so:
CPU: i7-4790K
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Have you monitored your system's resource usage(via Task Manager if you're on Windows)? Another point can be the orientation of your cooler and it's subsequent mounting to the processor as well as the airflow of your case.
What sort of temps were you sitting at prior to this observation?

How hot is your ambient air, and can you describe what sort of environment you run your PC in? Is this a small room with a closed door, do you have windows open, is this a large open space?
A system like yours shouldn't make all that much heat at idle, if it is truly idle (check task manager to see that your CPU usage isn't high). I'd expect a 4790K and GTX 970 to idle producing somewhere between 35w and 50w of heat, depending on your motherboard and other components, which is less than a single incandescent lighbulb. Generally the relationship is the other way around - high idle temperature is caused by high ambient temperature.
Bear in mind that if you're in a room with no air exchange, practically any source of heat, even human body heat, will eventually make the room uncomfortably hot. The heat has to go somewhere.
That said, 62-65c are actually great load temperatures for the components you have. Many with a 4790K see temperatures in the 80's or above.
