i5 3750k- Not downclocking when idle?

So i've been running this processor for about 3 days now with no problems. However, when running RealTemp I notice that the mhz are constantly fluctuating and rarely fall below around 2400 mhz and is often 3000+mhz.

So basically what I'm asking is if this is normal? Before my chip was idling at around 25-30C but now it is around 40C and even though this does not concern me it still seems odd.

I have tried changing performance settings in BIOS from high performance to balanced as Ive read in a few forum posts but this didnt solve the problem. Also im not OCing and have Turbo boost enabled.

Might as well post my specs:
Mobo: Asus P8z77-V LK
CPU:i5-3750k@3.4 ghz
Heatsink: Corsair H100
Ram: 8 gb of Corsair Vengeance DDR3 1600mhz
Power: 1000W

Thanks for your guys' time and any feedback would be awesome! And if this is a stupid question then Im sorry for wasting it

EDIT: Maybe the thread title is misleading, by downclocking what I really meant to say is something along the lines of down throttling, because as mentioned before im not OCing in the first place

If i under stand you correctly, you see that your cpu clock is "throttling".

etc, sometimes it will be say 4000Mhz(200x20)
sometimes it will be say 4200MHz(220x20)

For turbo-enabled cpus, this throttling is normal.

When my 8350 is turbo-enabled it never falls lower than its base clock (4.0) and will throttle as load increases/decreases.
I'm quite sure the 3570k shouldn't not be downclocking all the way to 2.4 since it's base clock is 3.4.

You sir, are awesome. I had a feeling it could be nothing but wanted to be safe. Appreciate the quick reply and the good news im very happy to hear this is normal. Thank you very very much!

Go into your BIOS and make sure EIST and other power saving features are on.
