Introduction

Anyone reading this review and not knowing about Cooler Master may be in the wrong place. The brand is as mainstream as it gets in the PC DIY industry and we here at TechPowerUp have reviewed over 100 Cooler Master products since the website started! These include cases, coolers, PSUs, peripherals, and fans, among other things. I've tested a few Cooler Master fans over the years, including the MasterFan MF120 Halo nearly three years ago—an eternity in the PC space! As it turns out, Cooler Master also thought as much when company representatives reached out to put forth the new Mobius fans for review.


The Cooler Master Mobius 120 comes in a few different options depending on whether you want an RGB version or not, and even with the former there are a few special editions! This review will focus on the Mobius 120 without any LEDs or first-party software/controllers to worry about. It's all about how well the fan does its basic job in pushing air through your case. Cooler Master claims the new Mobius fans use a ring blade design that has been optimized for a variety of use cases including as case fans or as part of air or liquid coolers too. This makes me think the fan is intended to be a hybrid one for both airflow-optimized and static pressure-optimized scenarios. Thanks to Cooler Master for providing review samples to TechPowerUp as we put this fan to the test today, beginning with a look at the product specifications in the table below.

Packaging and Accessories

When Cooler Master informed me about these new fans coming out, I was asked whether I'd be up for testing both the Mobius 120 and the Mobius 120 RGB. I wanted to see how the new fan design worked before committing to both and thus asked them to send along two units of the non-RGB model. Instead, and I am sure this is more to do with how press samples work, I was originally sent a press parcel containing one each of both fans inside a fancier box, without having the retail packaging. The photos above are just so you can see how it looked and to also ask readers whether they'd be interested in a review of the Mobius 120 RGB after all—let me know in the comments section.


Cooler Master then sent over another Mobius 120 in its retail packaging so I could go through the normal unboxing process while also having two samples for testing. The fan product box is flat and tall in profile while employing bold colors that we also see used on the product page itself. The Cooler Master logo shows up in a couple of different places along with a render of the fan and salient features listed on the front. Product specs are tabulated on the back along with marketing features in a few different languages and side flaps on the top help keep the contents in place during transit. Inside is a plain white cardboard inlay that is folded on one side to conceal the fan cable, as well as the only accessories here in the form of a set of four metal self-tapping screws to allow for use of the Mobius 120 as a case fan.
