Be Quiet! Dark Rock TF review -
Core i7 4790K Baseline test
Testing the coolers
Time to test. Today's tested cooler will work absolutely great with any processor from low to high-end (Core i3/Core i5/Core i7 quad-core and even six-core included up-to 130W) at default operating frequencies, of course there's room left for overclocking as well. We have built a new test system policy for cooling benchmarks.
Core i7 4970K Devil's Canyon baseline IDLE Temperatures
Let's have a look at the results for the system in its default non-overclocked state. Below, the IDLE temperatures, thus your processor is doing barely anything to nothing. Just sitting and waiting in your system.
The cooler obviously does not have any issue whatsoever in IDLE with the Core i7 4970K not overclocked.
If you have a look at the chart above you can see the processor LOAD temperatures (in the non-overclocked state). We measure in a 21 Degrees C ambient room temperature. Ambient temperatures do affect the cooling performance, albeit a little bit.
We note down the hottest measured CPU package temperature.
Guru3D's rule of thumb on CPU load vs cooling temps:
- Anything up-to to roughly 50 Degrees C or lower we consider enthusiast class cooling
- Anything in-between 51 to 60 Degrees C we consider performance cooling
- Anything in-between 61 to 70 Degrees C we consider mainstream cooling
- Anything above 71 Degrees C we consider average cooling
Above, we run wPrime 2 times, on the last run we measure the peak temperature which was 61 Degrees in the end of the 2nd run. And yes, that's with a Core i7 4790K.
Today we’re putting the new be quiet! Pure Power 12 M 850W power supply on our test bench. The company is mainly known for its PSUs and Hilbert has recently reviewed the Dark Power 13 1000W. On the same day (24th January), the Pure Power 12M series was officially announced. We reviewed the predecessors, be quiet! Pure Power 11 (in 2018, it earned the “Recommended” award) and Pure Power 11 FM (in February 2022, also “Recommended), and we wonder what has changed in the meantime for the Pure Power 12M. The main difference is the full ATX 3.0 compatibility.
