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 p5 500GB
– HDD: GOODRAM IRDM 1TB SSD
– PSU: Seasonic Snow Silent 750W Platinum
– Case: be quiet! Silent Base 802 White
– Thermal compound: Noctua NT-H2
Software used for testing the cooler:
– AIDA64 Extreme Version: 6.60.5900
– 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 Raijintek DELOS RBW has an average RAM slot clearance, as it will completely cover the first RAM slot and interfere with the second slot, on a standard ATX motherboard. With this cooler, medium to low height RAM modules are recommended to avoid any clearance issues.
The PCIe clearance is good enough, with approximately 34mm of space between the sides of the heatsink and the backplate of the graphics card.
Final thoughts
The Raijintek DELOS RBW is a small form factor CPU cooler that can handle an overclocked i9 9900K. This is thanks to its dual tower heatsink and three 92mm fans.
However, overclocking on such a small CPU cooler is not recommended with high TDP CPUs, as a small heatsink and fans cannot compete with a large air or water CPU cooler. In addition, the DELOS RBW is designed for one purpose, to cool a decently sized CPU while inside a small form factor system.
In terms of performance, with an overclocked i9 9900K, the DELOS RBW reached a maximum temperature of 92°C. This is a respectable result considering the type of heat and power that the CPU can produce. With the CPU running at its factory frequency and settings, the DELOS RBW reached only 71°C.
The build quality of this CPU cooler is good, the heatsink has no imperfections in its structure or all black coating. The fans while basic in their design have a solid frame and the impellers do not wobble.
However, while the Raijintek DELOS RBW is a good CPU cooler in terms of cooling, especially for its size, it has a few issues. First, the packaging is not great in terms of protection as it lacks any internal padding for the sides of the cooler. Second, the mounting system while working and solid, it is needlessly complicated. It has too many components and some of them are too small to be used on a CPU cooler.
In conclusion, the Raijintek DELOS RBW is a capable Small Form Factor CPU cooler that can handle an Intel i9 9900K CPU. However, while the cooler is a good performer, it has one main issue, the outdated mounting system which increases the difficulty of the installation process.
