Core i7 4790K OC at 4600 MHz 1.3 Volts

Now we up the ante. Understand that 1.3V 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 the Core i7 4790K @ 4600 MHz and apply 1.30 volts 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 at 4790K @ 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. 

The temps normally rise above and beyond 80 Degrees C for many heatpipe based coolers, which is a definitive no-no. As you can see, we have dangerous temperatures for most coolers. This cooler has no issues whatsoever. 

LCS class coolers do better here and then the EK simply ups the ante. The reality is that very few coolers and kits can actually manage a Core i7 4970K @ 1.3+ Volts / 4600+ MHz temperature wise well enough. So these are impressive results, let's up the ante and fire off even higher voltages at the processor:

 
So in four tweaked stages we up the core voltage from 1.30v upwards to 1.45v. Normally I can hardly reach 1.40v with any cooler, however, this cooler setup did allow me to reach 1.45 Volts (which is crazy for this CPU). That means there is a lot of cooling capacity available in this unit.  This one chart here shows really impressive numbers.
