be quiet! Dark Rock Pro 3 Review


be quiet! Dark Rock Pro 3 Testing:

Testing of the Dark Rock Pro 3 will be accomplished by installing the cooler into the test system case, rather than a test bench. Most systems are built and mounted into a (relatively) sealed chassis, so this method will be used to generate the idle and load results to give a real world view as to the cooling performance one can expect, based on the test system listed below. Of course, your results may vary by several degrees due to case design, case fan placement, and ambient air temperature. The CPU load is generated by Prime 95 version 27.9 for a period of two hours, with a cooldown period of one hour after the computer has returned to an idle state. Real Temp 3.70 is used to log the temperatures with the highest and lowest averages across the four cores of the Core i7 4770K test CPU. Ambient temperatures are kept at 24 °C during the testing to minimize the effect of temperature variations. Each cooler is tested with the manufacturer-supplied thermal compound as delivered.


Testing Setup:


Comparison Coolers:






Idle temperatures with no overclock come in at 28 °C, while it jumps to 67 °C under a load; both of which are fairly good. No thermal concerns here. Now, after we put the overclock in gear, the idle hits 33 °C, which is at the higher end of the tested coolers, and one degree higher than the smaller Dark Rock 3. That surprised me a little. Not really a problem, but I would have expected the Dark Rock Pro 3 to be a degree or so lower than the Dark Rock 3. Regardless, I cranked up the load while overclocked and the Dark Rock Pro 3 comes in at 82 °C, which is three degrees lower than the smaller, single fan Dark Rock 3. This is more in line with what I expected to see. We are still well below any thermal alarm bells going off, and be quiet! keeps the noise down yet again. Even with the cooler fans running at full speed, their sound is drowned out by the regular case fans.
