Now we up the ante. Understand that 1.3+ Volts is the level where Ivy Bridge processors get into problems due to the aforementioned heat-spreader versus TIM design solution applied by Intel.
We now set the Core i7 3770K @ 4600 MHz and apply 1.3 volts to 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
Okay, here are the IDLE results with the Core i7 3770K @ 4600 MHz with 1.3 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 will be the results.
The temps rise above and beyond 90 Degrees C for a handful of coolers, which is a definitive no-no. As you can see we have dangerous temperatures for most coolers. Enthusiast class coolers do better here, with the Noctua NH-D14 however it remains possible. We are quite surprised that this cooler seems to behave so much better compared to the others. The next in line is the Alpenfohn K2, Scythe Grand Kama followed closely by the Coolink Corator DS.
CPU cooler group test review with 3770K In this review we test over a dozen CPU coolers, mainly heatpipe based. We'll test them on a Core i7 3770K. In this group test we'll use Scythe, Noctua, Coolink, Deepcool, Alpenfohn, Gelid and Cooler Master coolers.
Gelid GX-7 CPU cooler review Gelid is a company that made a nice impression a year or two ago introducing themselves by releasing their first aftermarket CPU cooler, the 'Silent Spirit' cooler. After Gelid released that Silent Spirit and then Tranqillo CPU coolers it was time for a new model. Progress is made and anno Q4 2011 it's time to release their third consumer grade CPU cooler. Their latest creation comes in the form of a tower cooler called GX-7 -- aimed at gamers apparently.
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.
Thermalright HR-02 CPU cooler review We test and review the Thermalright HR-02 CPU cooler. Thermalright actually introduces this product as a passive CPU Cooler. The HR-02 is the second revision of the legacy Thermalright HR-01 cooler. We'll test it passively cooled yet we'll also pair it with Thermalright's TY-140 fan, a 1300 RPM fan that is silent, yet high performing. As stated, the results stunned me, this is really really good stuff.
