be quiet! Shadow Rock Slim

Testing

The following system was used to test the cooler:
– Processor: Intel i9 9900K @ 5GHz
– Motherboard: ASRock Z390 Phantom Gaming X
– RAM: GOODRAM IRDM PRO 16GB DDR4-3600MHz
– GPU: MSI GeForce RTX 2070 Super Gaming X Trio
– SSD: Crucial MX500
– HDD: WD 1 TB Blue
– PSU: Seasonic Snow Silent 750W Platinum
– Case: Phanteks Enthoo Luxe White
– Thermal compound: Noctua NT-H2

 

Software used for testing the cooler:

– AIDA64 Extreme Version: 6.32.5600
– Intel Burn Test v2.54
– Prime95 29.1

The cooler was tested with the CPU at the default turbo frequency of 4.9 GHz and overclocked to 5 GHz with a core voltage of 1.261 V.
Also, the included fans have been used at their maximum speed.
The room temperature was approximately 26°C (78°F), with 2°C margin of error.
The idle test consists of the CPU sitting idle at the desktop for 30 minutes, the temperature was measured at the end of the test.

 

The settings of the software used are the following:
Intel Burn Test v2.54 – Stress level: Maximum
Prime95 29.1- small FFT
AIDA64 Extreme Version – FPU Benchmark & Temperature monitoring.
Each test was conducted for 40 minutes.

 

Idle

 

Full Load – IntelBurnTestV2

 

Full Load – AIDA64 CPU, FPU & Cache

 

The noise level was measured at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 2 db.

 

The Shadow Rock Slim will not interfere with the RAM slots on an ATX motherboard. And in terms of the height, the fan will barely reach a standard sized RAM slot height.

 

The PCIe expansion slot clearance is good, with approximately 22mm of space between the heatsink and the graphics card. There is plenty of space to access the upper M.2 SSD socket.

 

Final thoughts

The be quiet! Shadow Rock Slim is an impressive little CPU cooler, it might not be ideal for overclocking, but it offers a good performance. This CPU cooler has two advantages over other models found around the 50 USD or EUR price. First of all, the Shadow Rock Slim has a great clearance for the RAM slots and a good clearance for the PCIe slots. The other advantage of this cooler is the low noise output of the 135mm fan.

The performance of the cooler is good for the dimensions of the heatsink. While it is not recommended for heavy overclocking, and especially not with a i9 CPU. The Shadow Rock Slim will work great with a high TDP CPU at stock settings and frequency. In addition, the cooling performance can be improved by the addition of a second 135mm be quiet! fan for a push pull configuration. However, by adding another fan, the overall price of the CPU cooler is increased.

The build quality of the Shadow Rock Slim is very good, close in fact, with the quality of the Dark Rock TF or the Dark Rock Pro 4. The edges of the cooling fins are smooth and straight, while the baseplate has a mirror like reflection.

The installation process is simple, this is thanks to a revision of the system in recent years. However, this particular mounting system while simple to use, it is still needlessly complex, with too many components used.

In conclusion, the be quiet! Shadow Rock Slim is a good and affordable air CPU cooler that offers a great cooling performance for its size. The clearance is also very good and the design will complement any system. The only inconvenient with this cooler is the complex mounting system which can be intimidating for beginners.
