Running it at full speed if not needed will just cause more power draw, louder noise, reduced fan life, and unnecessary wear on the rest of your system.
My cpu temp is around 50-60 while gaming .. is that ok
I was about to post the same question the OP asked!
I have just got i7 4770 and it came with BIOS settings of CPU fan: Full Power and System fan: Normal.
I also have similar temps. If I set the CPU fan to normal temps at idle are around 40+ which I don't think is normal.
When gaming temps are around 70C.
