Now we up the ante. Understand that 1.3V and higher Voltages are the levels where Ivy Bridge processors get into serious problems due to the aforementioned heat-spreader versus TIM design applied solution from Intel. We now set the Core i7 3770K @ 4600 MHz and apply 1.30 volts on the CPU while loading it with 100% stress for a full Prime95 run on all available CPU threads.
Core i7 3770K OC At 4600 MHz 1.3 Volts - IDLE
Below, you can see the IDLE results with the Core i7 clocked at 3770K @ 4600 GHz with 1.30 volts on the CPU. Again, the results are the IDLE temperatures thus you are in your desktop doing nothing.
Core i7 3770K OC At 4600 MHz 1.3 Volts - LOAD
Now we'll be testing the temperatures under stress. If we set the overclock at 4600 MHz and configure CPU Voltage at 1.3V, these are the results.
So for the NH-U12S the temps rise above and beyond 80~85 Degrees C, that is a definitive no-no. But as you can see, we have dangerous temperatures for most heat-pipe based coolers.
LCS class coolers do better here, however the NH-U14S might have a fairly hard time keeping up but it's not bad. The reality is that very few coolers and kits can actually manage a Core i7 3770K @ 1.3+ Volts / 4600+ MHz temperature wise, but with two fans I'd be comfortable running this overclock. And remember... this cooling level is at 100% silence.
Noctua NH-U12S and NH-U14S review We test and review the Noctua NH-U12S and NH-U14S CPU coolers. Both coolers have recently been introduced into the channel with kicks performance and versus some really nice airflow OWM controlled fans that are drop-dead silent. Hey, it's Noctua .. so you know it's good, let's check out the review shall we ?
Noctua NH-C14 CPU cooler review In the long line of Noctua CPU coolers they introduced another CPU cooler, tagged with the name NH-C14, the heatpipes bent in a C shape and armed with not one, but two Noctua NF-P14 FLX 140mm fans this product is bound to keep any CPU released to date nicely cooled and chilled.
Noctua NH-D14 review It is called the Noctua NH-D14 premium cooler -- but as I like to call it ... the Big Ben. Noctua had to go back to the drawing board and came up with the NH-D14 premium CPU cooler. It is a six heatpipe dual radiator design to improve both cooling performance and noise levels. Obviously what catches the eyes is that dual radiator uneven design with a 140mm fan sitting smack down in the middle of the cooler.
Noctua NH-U9 and NH-U12 heatpipe coolers A new trend that started over the past two years is heatpipe based cooling. Several advantages directly come to mind as the principle is quite simple. You move heat towards another spot other than the source. That way you can get rid of that heat not directly away from that source, yet effectively can cool it down optimally on location B. This means less resources and effort is needed at the original point of heat. The less resources I'm talking about is a direct active form of heat dissipation e.g. loud fans. More cooling these days equals more noise, and don't we all hate it ?
