Q: Macbook Pro Retina Extremely Hot when CPU is at Idle

I have a mid 2012 Macbook Retina running the latest OS El Capitan.

CPU: 2.7 GHz Intel Core i7

Memory: 16 GB 1600 MHz DDR3

After 30 seconds of starting my computer up the fan turns on as the temperatures climb to 135 degrees on Idle. The temperature will go even higher if I watch Youtube videos or do anything that requires the CPU to work hard.

On my activity monitor its showing that my CPU idle is around 95-98%. No applications are running in the background as well. I've already tried resetting all the ram and it still does not work

Any other suggestions?
