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 apply 1.30 Volts / 4600 MHz to 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. 

If you expected more, well the kit is set up based on sheer silence. So while there is a lot of capacity left the cooler will continuously balance in-between silence and cooling capacity, preferring acoustics.

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 1.35 Volts most heatpipe coolers, for example, would fail whereas the EK LCS still pushes acceptable temperatures.

The cooling capacity is a little over-utilized in favor of acoustics. You can see it performs really well but we also know it'll become noisy. Some manufacturers forfeit a bit on cooling performance in favor of silence, for EK that is reversed. However, remember, you can create your own fan profile and find a balanced setting you prefer, cooling capacity wise the kit definitely shows potential.
