Noctua NH-U12S and NH-U14S review -
Core i7 3770K OC at 4600 MHz 1.2 Volts
Overclock Sessions At 4600 MHz 1.2 Volts
We had a peek at a selection of stages in overclocking and their respective temperatures, have a look at the following results please.
- We enforce 4600 MHz onto the processor clock frequency by changing the multiplier
- We give the processor 1.20 Volts and then (next page) later on 1.30 Volts
Core i7 3770K OC At 4600 MHz 1.2 Volts - IDLE
So first up some IDLE results with the Core i7 clocked at 3770K @ 4600 GHz with 1.2 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 1.2 Volts - LOAD
Now we'll be testing the temperatures under stress. If we set the overclock at 4600 MHz and configure CPU Voltage at 1.2V, these will be the results.
As you can see, the temperatures are bumped up higher quickly once you apply a Voltage tweak. Overclocked with 1.2 Volts we see some heatpipe coolers already run into problems. That Core i7 3770K simply is a nasty product when v-tweaked.
My rule of thumb is simple:
- If the processor can stay under or at 75 Degrees for a long period of time, you will be okay
- Good would be under 70 Degrees C
- Excellent cooling can keep it under 65 Degrees C
We notice that the NH-U12S is doing well, but already running a little short. That cooler as such is good enough for normal usage and a small tweak. The NH-U14S however is much more impressive. With two fans 66 Degrees C and 68 Degrees C with the one fan.
Let's go nasty though and fire off 1.3 Volts and a 4600 Mhz clock frequency to see how these heatpipe coolers will panic :)
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 ?
