Sometimes it is nice to ignore all responsibilities and catch up on sleep. After a month of immense workload, I found myself completely exhausted and with absolutely no motivation to move. The result of this was basically having a full day of lying in bed. I did feel a bit of guilt about not doing anything that day, but I coped with the thought that it was some needed rest. With that, I spent the entire day either asleep or watching interesting videos on YouTube. As interesting as the videos were, I often found myself falling back asleep as I had proved to be that exhausted. Being able to have my mind just shut off was quite nice in my personal opinion. Perhaps it is from the stark contrast between going all out on your personal work and having your own personal time. I just find it quite nice to have times where you can be at full throttle and other times where you enter a state of becoming a human potato. It is almost like you are toggling your own performance in a way, just like how the Cooler Master Mobius 120 OC can toggle its own performance to multiple levels. It is nice to have the option to adjust performance to fit your own desires. With that said, the previous iterations of the Mobius series were seriously interesting and good. Will this new iteration of the Mobius 120 OC fan provide me with a satisfying experience or will it leave me bored and asleep? Keep reading to find out!
Today’s review unit of the Cooler Master Mobius 120 OC was shipped to us here in Calgary, Alberta, Canada via USPS with Canada Post as a transfer from Brea, California, USA. The white cardboard box was handled quite carelessly, as it arrived in slightly damaged condition with a large dent on the edge of the box. I was slightly concerned about the shipping because of the condition of the box, but everything inside remained intact with no marks.
Taking a look at the boxes, both the Cooler Master Mobius 120 OC share a similar retail design to its predecessors, the Cooler Master 120P ARGB and Mobius 120. The color scheme of the box is a nice purple, pink, and blue, giving it quite a different look compared to its competitors. On the front, the Cooler Master logo is placed on the bottom left with the respective names on the top right. As with most retail boxes, the product is displayed prominently on the front, taking up the rest of the box. A notable difference is how the Mobius 120 OC’s box does have a flip open door that uses Velcro. This door displays the fan when opened. The general design is quite flashy and is a real eye catcher. The back of the box sprouts some specifications for each respective fan as well as some additional features. While I do understand the flashy design, I personally prefer a more simplistic aesthetic as I find it to be clearer, but this is more so personal preference.
Before we continue, here are the specifications for the Cooler Master Mobius 120 OC, as obtained from the manufacturer's website:

Our packs of the Cooler Master Mobius 120 OC arrived as single units. The fans fit nicely inside the boxes alongside the included mounting screws and wires. Surprisingly, there is no manual, which is strange, but it is not the most useful document for a fan. In this case, I would believe it to be useful as a speed control line is not often utilized for most fans. Cooler Master provides minimal packaging, which I personally appreciate, as I enjoy only having the essentials for single fans.
