EK Quantum Impulse 120 D-RGB Fan Review

The EK-Quantum Impulse 120 D-RGB is an RGB fan destined for quiet operating systems. It is not a high performance fan, because of the not high rotation speeds that it achieves, trying to balance performance and output noise. A magnetic levitation bearing, increases its reliability. 

According to Wikipedia, EKWB, better known as EK Water Blocks, is a Slovenian company founded in 2003 that manufactures high-end computer water cooling, extreme cooling, and some air-cooling components for CPUs, GPU, RAM, and SSDs. Its target audience is enthusiasts or pro users aiming for the best cooling performance.

My friend Dave sent me a message some weeks ago asking if I would like to test the EK-Quantum Impulse 120 D-RGB (Impulse from now on) fans on my Longwin machine. I accepted the challenge, of course, and after some days, the EK package arrived at the lab. This is an expensive fan, currently going for €29, so it is very close in price to the performance king in the 120mm category, the Phanteks T30-120, which lacks RGB lighting, though. The Impulse fans have the VAPO™ bearing and Magnetic Levitation motor provided by Sunon, so I am anxious to see how they perform. The Phanteks mentioned above fan also uses a MagLev bearing.
