Fractal Design Lumen S28 RGB – Cooler that shines with all colours

CPU coolers, Extra tests | | Pavel Sekerka

Today I would like to introduce you to the Lumen S28 RGB liquid all-in-one cooler from Fractal Design. This cooler attracts with its discreet and simple design, which can be easily enlivened with RGB LEDs and uses an atypical build with a pump in the radiator. So the question remains whether this solution is an effective enough alternative against conventional AIO coolers with a pump directly in the block, which of course I intend to test in today’s review.

Results – 39 dBA


Why is there a missing value in the chart for some coolers? Because the cooler could no longer handle the load in the specified mode, or because the fan could not be slowed down to the required level, this is typically the mode with the lowest noise level.

Do you know how a heatpipe works? A DeepCool representative, in a talk at HWCooling Techtour ‘26, looked under the hood. In other words, he explained much of what often remains hidden. This included how they approach development and what they work on internally. That, too, was part of the program, which you can watch. The physical samples, which were also on display, come only at the very end of the whole journey. Read more “Cooling Topics at HWCooling Techtour ‘26 Belonged to DeepCool” »

Analysis, CPU coolers | | Ľubomír Samák

The purpose of a CPU cooler is to transfer enough heat away from the processor so that it can operate within its optimal parameters, for example clock speeds. These are only achieved within the expected range if the processor, in combination with the cooler being used, does not heat up more than is desirable for achieving attractive performance. Yes, everything usually revolves around speed, but that is also associated with factors such as power consumption. Read more “How a CPU Cooler Works. Intended for Secondary Schools” »

Computex 2026: New Hardware Outside the Main Spotlight

Cooling, News | | Michal Pavličko

Computex is not just for the industry giants. Alongside major manufacturers, smaller brands regularly showcase unconventional designs and innovative engineering to capture attention. Some of these concepts prove to be developmental dead ends, while others pioneer features that later integrate into mainstream products. Even if not every innovation succeeds, many certainly deserve recognition. Read more “Computex 2026: New Hardware Outside the Main Spotlight” »
