    Why is my i5-4590 showing 100% use with prime95 but runs at 128 F and uses 42 watts?

      It's in a Dell. The ms/iteration times are around 39-45 which is slower than my i5-2400 at 21-25 ms/iter. Memory is DDR3-1600, 4 G. Using two different hardware monitors, the only difference I can see is the i5-4590 is running at 42 watts and the i5-2400 is at 83 watts, and 165 F. Speed step off/on, turbo boost off/on, no difference. Dell has replaced the motherboard, no difference. Any ideas?
