Fan test
Now let’s get to the long-awaited hard facts and figures, and let’s start with some light fare first, i.e. the fans. As usual, I put the EOS 120 MM PWM ARGB up against our reference fan Noctua NF-A-12 PWM. Today, however, there is only the slim radiator test, since we also have only one slim radiator in the set.
The delivery rate of the EOS is somewhat higher, but unfortunately so is the noise level.
In a direct comparison of throughput per dBA, however, the EOS has to admit defeat, because the Noctua fan is significantly quieter.
Sound comparison (recording) at 100% speed
As just mentioned, the subjective feeling is a slightly more distinct noise from the motor and the rotor blades, which is of course also due to the higher speed. The reference fan produces slightly less noise and especially motor noise.

Noctua NF-A12 PWM
As a cautionary example of what’s really loud at around 1800rpm, I’d still have a cheap case fan from a PC table labelled on a rather high priced Taiwanese case supplier that could easily have been used to run octocopters through:

Again, the soundstage of the EOS is a bit more concise than that of the Noctua reference fan.

Frequency spectrum in the housing
Next, let’s look at the frequency analyses of all measurements for all fans measured and all speeds tested. The graphs speak for themselves, as you can also see a small lower frequency peak of the engine at full speed quite clearly:
Cooling performance CPU block in comparison
Next, let’s take a look at the cooling performance of the Forkis CPU block. The whole thing was tested in a fully air-conditioned chamber. This has a volume of just over 65 m³ and can be set to a permanent and constant 20° room temperature. Tested with Prime 95 and a Ryzen 7 3800X overclocked to a fixed 4.3GHz (all-core), the result with all three flow rates is astonishing, as even though the Alphacool XPX would be better replaced here on the Ryzen with a more purpose-built XPX Pro, the Forkis beats both the Alphacool waterblock and, more importantly, EKWB’s Magnitude, which was again a bitter disappointment.
Summary and conclusion
Raijintek has really delivered here, that must be conceded first of all without envy. And not only in terms of workmanship, but also and especially with the CPU water block and its performance. Here, well-known and high-priced top dogs are even put in their place very clearly and that too at an astonishing price. I wouldn’t have expected that at first. The used and revised Antila D5 Evo is also excellently processed and leaves hardly anything to be desired.
I am someone who always looks at cheap prices critically, but cheap does not always have to be bad, quite the opposite – for a package price from 360 € you really get a lot for your money. Excellent workmanship, chic design and first-class cooling performance – what more could you want? I am surprised that other manufacturers call such sets quite also over 500€, because Raijintek shows us without a doubt that it also goes with less money.
Other providers are welcome to take a leaf out of their book. I can give a clear buy recommendation here. Today, you don’t buy cheap, you buy twice. On the contrary, here you can even strike with a clear conscience.
