I hate to burst your bubble but I don't think your temps are being read correctly. Coretemp and Speedfan were reading 15C to low from what i've heard. People are still having problems with V4.33 I would download Intel Tat and Everest and see what they say. Your temps should be reading.
Idel:
Core 0: 43C
Core 1: 42C
Core 2: 42C
Core 3: 43C
Load:
Core 0: 60C
Core 1: 60C
Core 2: 58C
Core 3: 58C
I'd say those temps are a bit more accurate especially on stock cooling.
