You should first get your load temps. many users idle at 30-35 but still load at 55 so if you idle 48 and load at 55 i would see no issues(with the exception to the fact that you are using a bit more power)
If you want to try those, they will lower idles(i am not sure how much with the low multi on a 6300), but do nothing for loads anyway
Turn them on and set your power settings in windows to portable/laptop.
Both the settings effect the cpus idle temps in a slightly different way
Speedstep drops voltage and clock speed by the multilayer. So in my case i go from load at 3.0(9 multi) to idle at 2.0(6 multi) and a voltage of 1.2 to 1.12. This gives my quad idle temps of 30-35, but the loads are still 48(on a cool day with high fan speed) to ~57 with the boards fan control on.
C1E does not change speed as far as i know(there are users here that can describe it much better), but does do voltage. I did note a cooler idle temp with it.
On some boards with an overclock these option do not work right, so you will need to test stability again(i have had no problems, but one board, the P5W DH, will not allow[grayed out] it when I change the voltage).
