Given the low price of the Juno Pro RBW, which requires the addition of RGB lighting, it is hardly surprising that the cooler has some cost-cutting features.
In contrast to the boxed coolers from AMD and Intel, the cooler is not produced by extrusion, but relies on radially arranged black fins. There are no heatpipes, so the heat is transported purely through the lamellas. A similar design, in which the fan is framed on the side by fins, is probably familiar to many from older Zalman coolers.
A special feature of the production method used here is that the Juno Pro RBW does not have a proper base plate. Instead, the individual slats were connected to the floor and sanded down. The resulting result, compared to more expensive CPU coolers, is quite dainty: The resulting base plate is small, with oblique incidence of light the individual lamellas can still be seen.
The fan sits on the blades and is held in place by a proprietary frame, so it cannot be replaced. The frame also houses the RGB LEDs that provide the lighting.
The fan is connected via the usual 4-pin PWM connector. Despite the RGB lighting, there is no suitable connection; instead, the cooler takes over the control of the LEDs itself and uses the power supply of the fan for this purpose. For this reason it can only be operated at four-pole connections, as otherwise the LEDs do not have access to a constant 12V line.
However, the cooler does not get by completely without control: There is an additional button with which you can optionally deactivate the lighting. The fact that this is not fixed allows theoretically a free positioning, but the other cables and also the blue button are not conducive to the optics.

The Raijintek Juno Pro RBW uses the standard mounting system on AMD sockets, which is also used for the company’s boxed coolers. Accordingly, the mounting system is compatible with all common AMD sockets.
To mount the cooler, place it diagonally on the CPU while hooking the first retaining ring into the retention kit. Contrary to the comfortable lever solution used by AMD, the second retaining ring must be pulled manually over the opposite retaining lug. That costs a lot of power and is not very comfortable. A slightly more comfortable alternative is to loosen the screws of the retention kit on one side and thus bring the hook a little further to the retaining rings. Then you can put them on and tighten the screws again. The same procedure is also recommended for dismantling the cooler.
These retaining rings are also used on Intel sockets. A plastic frame is attached to these, which serves as a link to the Intel socket holes. This frame is again fastened with push pins.
Although the installation allows a stable fastening, the installation concept is not perfectly mature. The installation on the AMD system used by us was to be realized in good conscience only by the described trick, since the metal holding bridge of the cooler to be bent is very rigid, in order to make an acceptable holding force possible. A direct screw connection or a lever mounting, as with AMD’s boxed coolers, would have been a better alternative.
