I've got a Haswell i7 4770k, and have never overclocked it. The fan I am running is a hyper 212 EVO and a Z87 pro mobo. I just noticed today my temps in game jump between 50-70 randomly. I also am noticing on bootup that sometimes the cpu fan shows as its resetting itself, yet it never stops spinning.
On idle it stays at about 38-41 and never jumps/spikes.
