be quiet! Dark Rock TF Review


be quiet! Dark Rock TF Testing:

Testing of the Dark Rock TF 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.

Comparison Coolers:






As we start the system and let everything stabilize, the idle temperatures with no overclock settle at 27 °C, while the temperatures jump to 68 °C under a load. This is impressive, even if we stop right here. But of course we don't stop just yet. After we put the overclock in motion, the idle hits 31 °C, which is just fine. No surprises here. Now when we crank up the overclock and load CPU, the temperatures come in at 75 °C. Yes, just 75 °C, which is really impressive. One thing to keep in mind is that the Enthoo Primo test case is large and has plenty of airflow. So you can likely expect to add a couple of degrees for a small case. The sound output of the cooler fans was typical with be quiet!. Under a full load, the case fans pretty much drown out the cooler fans. And at idle, even if you stick your head in the case, you can't really hear them.

The Dark Rock TF keeps the temperatures in the neighborhood of some other impressive coolers - air and liquid. If you are building a system in a small case, you now have a thermal solution that will make short work of the heat and fit in a small case. The Dark Rock TF definitely keeps overclocking on the table for low profile applications.
