Super Flower Megacool 140mm Fan Review – The Hurricane!

Epilogue

After the high-performance Megacool 120mm, its larger sibling arrived, offering more airflow but not as high static pressure since the larger diameter sets the limits here. In the table below, you will find the maximum performance values of both Megacool models in all of their speed modes. I use the 140mm model as a reference for the “difference” column in the tables below.

Low-Speed Setting

Mid-Speed Setting

High-Speed Setting

I won’t hide it. This was an exhausting review. Having three different speed modes is a great feature, but in terms of measurements, this means triple the work since I have to repeat all tests for every mode. In any case, having the option to change the fan’s speed through a button on the provided control is a great feature, especially since you can control the speed of all fans at once!

The Megacool 140mm is a performance beast, which requires lots of power, though, so be careful! You must use the provided extension cable that gets the required power from a SATA connector. This is crucial if you plan on daisy-chaining two or more of these fans. Most mainboard PWM headers can deliver up to 1A max. Even the Corsair Commander Pro I use for my fan tests has a top limit of 1A per port or 4.5A total, so if you don’t use the provided cable and try to power two of these fans, you will probably fry the corresponding header’s power circuit. It will only survive if it has OCP protection, which I don’t expect on cheap mainboards and PWM controllers. So remember, use the provided SATA adapter to power the fans instead of using the PWM header’s power output. 

Look at the following table for Amperage information.

Now that I explained why you must use the provided SATA connector let’s proceed to the rest. The build quality and performance are top, although the static pressure is not as high as the claimed one, and the airflow is close enough to the advertised value. The double ball bearing is much more tolerant to high operating temperatures and, thus, preferred for operation in harsh conditions. Still, it is way noisier than a fluid dynamic bearing, and this is shown in the noise-normalized tests, where the Megacool achieved the lowest RPM in almost all tests. Compared to other fans, the lower RPMs didn’t allow optimal performance; hence, the Megacool doesn’t score well in the normalized noise performance tests, mostly in static pressure. Even at a high noise level, 45 dBA, compared to the only other 140mm fan that can reach this noise level, the EKWB EK Loop FTP 140 D-RGB, the static pressure is notably lower, showing that the Megacool is mostly for chassis use if you care about noise output. From 35 dBA and higher, airflow is high enough, while at lower noise levels, airflow performance is mediocre.

All of the above means that the Megacool is mostly for chassis use, where high airflow is the crucial element unless you want a powerful 140mm fan that will cool down equipment in a server room, for example, where noise output is not a problem. Few 140mm fans can deliver close to 170 CFM of airflow while exceeding 5 mmAq static pressure. The remote control functionality is a bonus since you can change the fan speed even if you are in a different room. I tried that, and it worked like a charm! In terms of pure performance, the Megacool is the strongest 140mm fan I have evaluated so far, in both airflow and static pressure at its full speed, but beware that for this kind of performance, you will need earplugs if you plan on being in the same room with the fan.

The fans with the better performance at low noise output levels are the following:
