The core 9xx series procs do run hot. As the above user suggested, if you aren't going to OC, you might as well undervolt the CPU. It will cause no hard (instead will increase the life of the cpu), and decrease ur temp and wattage used. You can play the trial and error game to see how low you can go (as soon the system becomes unstable, you know the limit).
If you are going to OC, you will need an aftermarket cooler, like the hyper 212. Also sience you are using the stock cooler, u are using the sock thermal paste? just replacing it for some AS5 thermal material will drop ur temps by as much 5-10C under load.
Its in the Bios, your CPU voltage will be somewhere between 1.3-1.4v Start lowering the value in small increments until you go as low as you can while being fully stable. With no OC, I bet you can easily drop .15v
