Processor at 4600 MHz with Higher Voltage

The processor at 4600 MHz with higher Voltage

Now we up the ante. Understand that 1.30V and higher voltages are the levels where Haswell processors get into serious problems due to the aforementioned heat-spreader versus TIM design applied solution from Intel. We now set apply 1.30 volts / 4600 MHz all cores on the CPU while loading it with 100% stress for wPrime to run on all available CPU threads three times. Below, you can see the IDLE results with the Core i7 clocked @ 4600 GHz with 1.30 volts on the CPU. Again, the results are the IDLE temperatures thus you are on your desktop doing pretty much nothing. 

Not the best i agree, but given the radiator surface area and the fact it's a heat pipe cooler, not bad at all either. Let's advance a bit more.

To advance on overclocking to see where our thermal threshold (the point of no return) is we tweak in four stages where we up the core voltage from 1.30v upwards to a more (unrealistic) 1.40v. At 1.4 volts any heat pipe cooler would fail and yes so does this one. But I'd be comfortable running 1.30 Volts sure.

The cooling capacity of a heat pipe cooler is always way worse than LCS capacity wise. Above the cooler compared to a D15 Silent model from Noctua and a Corsair H115i Platinum.
