Recently I purchased a cm hyper 212 evo to do a little bit of overclocking on my fx 6300 and after looking at current temperatures I'm more confused than ever.

I've used HWMonitor, AI Suite II's Sensor and HWiNFO64 and they all show different names for things and I don't have a clue. The processor is still at stock speeds at the moment.

After ~30 mins of prime95 to get the cpu up to max temp here's what each program says:
- AI Suite: CPU 32C idle, 43C load
- HWMonitor: ASUSTeK COMPUTER: Temperatures: CPU: 32C idle 43C load
AMD FX-6300: Temperatures: Package: 11C idle 23C load
- HWiNFO64: CPU [#0] AMD FX 6300: CPU 0: 12C idle 28C load
ITE IT8721F: CPU: 30C idle 43C load

Which is the temperature I should go by for my overclocking?
How much of an overclock should I anticipate with the 4+2 power phase of my Asus M5A97 R2.0 motherboard
