Coolermaster R4 Series 120mm LED Cooling Fans Blue & Green Unboxing & First Look Linus Tech Tips

The video opens with Linus Tech Tips taking on a rather unusual unboxing request for Cooler Master R4 Series 120mm LED cooling fans, highlighting both a green and a blue LED version. He notes the packaging and the two colors are essentially the same product with color differences, and he walks through what you get in the box including the six-blade sickle-flow design and the three-pin power/RPM monitoring connector. Linus demonstrates a quick power-up by shorting the green and black power pins to run the fan outside a computer, then plugs the green version into a power supply to show it running with a green LED glow and a visible black frame with green LEDs. He then swaps to the blue version, explaining that it shares the same form factor and performance characteristics, and compares the blue and green lighting aesthetics. Throughout, he comments on the build, mentions that the LEDs are housed rather than glued in, and points out the potential to swap LEDs if desired. The segment also includes practical tips, such as how to test the fan outside a system and a note about using them as intake fans for visual impact. In closing, Linus corrects a common label error by distinguishing Cooler Master from Corsair, and he encourages viewers to subscribe and check his other channel. The overall takeaway is that these fans are visually striking, perform roughly as expected at around 2000 RPM, and offer flexible LED customization with a strong emphasis on appearance and practical testing.
