Raijintek Mya RBW Rainbow Review: Addressable RGB LEDs and Good Cooling

In December 2018, Raijintek added another product to its Round-Up CPU cooler. The new CPU cooler is called MYA RBW and is a normal tower cooler. According to the manufacturer, the MYA RBW is particularly characterised by its high processing quality and heat dissipation. The latter is to be achieved by wave-shaped heat sink fins and optimized air disturbance channels. The cooler is black anodised and the lid is equipped with a digitally addressable RGB element to ensure that the appearance is not neglected. Whether the investment of Price not available * is worthwhile and how the Raijintek MYA RBW generally performs, we will find out in this review.

Packaging & Scope of delivery

The MYA RBW comes in a relatively small cardboard box. This is colorfully printed and contains lots of information and pictures about the cooler and the supplied fans. This information is only available in English.

If you open the upper flap, you will first come across a thin foam element and the installation instructions. This manual is relatively small, but in several languages and with very large and easily recognizable pictures. The heat sink with pre-installed fan or RGB element is hidden directly underneath. Last but not least there is a box with all mounting accessories, some heat conducting paste and two additional fan clamps. Other accessories, such as a long screwdriver for mounting, are unfortunately not included.

Design & Processing

The black anodized aluminum fins and heatpipes make the cooler look very chic. The heat sink consists of a total of 37 aluminium fins and six 6-millimetre copper heat pipes. Compared to other manufacturers, Raijintek does not rely on a nickel-plated base plate but on the Direct Touch process. The heatpipes are ground flat and rest directly on the heatspreader of the CPU. Overall, the heat sink is large, but doesn’t look too massive. In addition, the heat sink is asymmetrically designed to ensure compatibility with higher RAM modules.

The included fan is of the type Raijintek BDM12013S and is completely black including 4-pin PWM cable. It rotates at a maximum of 1400 revolutions per minute and is a slim fan with a thickness of just 13 millimetres. Raijintek would like to improve the RAM compatibility of the MYA RBW by this as well.

In order to realise RGB lighting, the manufacturer has attached a plastic cover to the cooler with four screws. If this element is unscrewed, it is divided into a black plate with the Raijintek logo and a slightly thicker, slightly transparent element. This contains two RGB LED strips which can be connected to the mainboard via a 5V RGB connector.

The finish of the Raijintek MYA RBW is good. After dismantling the fan, you could see at the edge where the anodization had already suffered a bit. The assumption suggests that these quirks were caused by the very tight holding clamps.


A test system on a benchtable is used for the review. This allows us to rule out factors such as heat build-up in the housing. The test system consists of the following components.

Even if the assembly looks very simple on the pictures of the enclosed manual, in reality it turns out to be quite complex or even unnecessarily complicated. But let’s start at the beginning. A universal backplate for all sockets is used to fasten the heat sink. This has foam material and various drillings. First you have to insert four long screws through the holes of the backplate. Here it came directly to the first smaller interruption. The holes in the foam are so small that the long screws can only be pushed through after a few attempts. The mainboard is then placed on the backplate, followed by four insulating washers and four spacer bolts. These have unfortunately a thread and must be tightened with unnecessarily high expenditure and with the help of a screwdriver firmly.

Once this has been done on all four corners, the mounting frame can be placed on the spacer bolts and fastened with four additional screws. Then two spacers are attached to the mounting frame so that the retaining bracket can also be screwed on properly afterwards. This retaining bracket is not permanently mounted on the radiator, but is inserted and simply locked in place with the aid of two retaining lugs. After applying some heat conducting paste, the cooler is placed on the CPU and the retaining bracket is screwed to the retaining frame. Since one of these screws is located directly under the heat sink, a normal screwdriver was much too short to reach the screws. Why the manufacturer does not put a suitable tool here, is a mystery to us.

In the end, the disappointment became even greater. Despite the tight screw connection of all components, the heat sink is still easy to move and twist. Raijintek was to definitely rework the way of assembly. Especially for beginners this is unnecessarily complicated. There are some manufacturers who have solved this much more elegantly.

Where the MYA RBW shouldn’t have any problems would be with memory locks with high heatspreaders. Due to the asymmetrical design and the narrow fan, there should be no compatibility problems at least on motherboards with four memory banks on the right side.


Compared to other coolers from Raijintek, the MYA RBW does without a fan with RGB LEDs and instead equips the lid of the CPU cooler with RGB elements. As mentioned before, this essay is made of two plastic elements. In the lower element Raijintek has attached two LED strips with 8 LEDs each. These can be connected to the mainboard via a 3pin 5V RGB header and addressed digitally.

Volume and cooling capacity

As already shown in the previous chapter, we use as test hardware an AM4 system based on the Ryzen 5 1400 and the MSI B350 PC Mate. The Ryzen runs on standard clock at 1.1 volts.

To heat up the processor, the processor was loaded with Prime95 for 15 minutes. The temperature of the CPU was then read out with the CPUID hardware monitor. This test was performed in two different scenarios and then compared with the values of the AMD Boxed Cooler (Wraith Spire). During the temperature measurements the room had a temperature of 21°C.

Cooler Operating scenario RPM Temperature
AMD Wraith Spire, 3.2 Ghz, 1.1V 50% PWM 1600 rpm 53°C
AMD Wraith Spire, 3.2 Ghz, 1.1V 100% PWM 2600 rpm 47°C
Raijintek MYA RBW, 3.2 Ghz, 1.1V 50% PWM 1000 rpm 42°C
Raijintek MYA RBW, 3.2 Ghz, 1.1V 100% PWM 1500 rpm 39°C
Raijintek MYA RBW, 3.8 Ghz, 1.25V 50% PWM 1000 rpm 68°C
Raijintek MYA RBW, 3.8 Ghz, 1.25V 100% PWM 1500 rpm 61°C

As you can see from the table, a Ryzen 4 1400 that is not overclocked does not present a real challenge for either cooler. With 42°C under Prime95 load and only 1000 rpm the MYA RBW reaches a very good value. In addition, despite the narrow fan, it does its job significantly quieter than the AMD boxed cooler. If you overclock the Ryzen 5 1400 and leave the voltage in the UEFi at “Auto”, it increases from 1.1V to 1.25V under full load. Here, too, the CPU cooler still cuts a good figure at full load with 68°C. The Raijintek MYA RBW does not need to hide its cooling capacity.

Résumé of the Raijintek MYA RBW Review

The Raijintek MYA RBW is a high-performance CPU cooler with chic optics and RGB lighting. In addition to these positive features, there is the high RAM compatibility due to the asymmetrical design, the quiet fan and the good workmanship of the heat sink.

What impressed us less was the mounting system and the fact that no mounting tool was included. The assembly is altogether too complicated, without a screwdriver with a long shaft hardly feasible and in the end doesn’t even look really solid. If you also consider that the cooler costs a full Price not available *, it seems to be a bit high for the total package. The competition offers RGB-capable CPU coolers starting at 30 €. In order to be successful, Raijintek must either reduce the price or improve the assembly and above all enclose a suitable tool.
