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: 6.32.5600
– 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.
Final thoughts
The Raijintek EOS 240 RBW can be bought for approximately 70 USD or the equivalent in EUR. This price is the main reason you’ll want to get this CPU cooler, it’s a good price for what is a good performing CPU cooler. It’s not the best CPU cooler out there, however it does perform good enough for a gaming system.
The cooling performance is good; however, the noise output could have been lower. Especially with fans which spin at 1800RPM, other fans within the same RPM range are quieter.
Another shortcoming of this CPU cooler in terms of the noise output is the pump, it is not particularly loud, however, the actual noise it generates is quite irritating as it’s high pitched.
The build quality is good, even though a lot of parts used on this cooler are made from plastic, the biggest offender being the CPU block. The plastic used is solid and should last a long time, however it gives the cooler a cheap feel, which is not the case.
The installation procedure is very easy thanks to a mounting system that has some thought put into it. The system uses the bare minimum of components and is straight forward, a thing which a lot of manufacturers do not offer.
The design of the cooler is good, with plenty of RGB LEDs installed inside the CPU block and the two 120mm fans. The EOS 240 RBW will match any system and configuration, as its design is neutral.
This CPU cooler is best used on a gaming system, it should not be used for extreme overclocking or be compared with expensive high-end CPU coolers. What the EOS 240 RBW offers is a good design with a good performance, albeit the noise of the pump could have been lower.
In conclusion, the Raijintek EOS 240 RBW is a good CPU cooler that performs well. It has plenty of RGB and a design that can match anything you’ll throw at it. The installation is easy thanks to a good mounting system. The only drawback of this CPU cooler is the noise output of the pump.
