Super Flower Megacool 120mm Fan Review – The Performance King

Epilogue

I measured 0.75A with the fan operating at its full speed (3382 RPM) and given that these fans can be daisy-chained, I should start with this piece of information first: how many Megacool 120mm can you connect in a daisy chain without damaging the primary connecting cable, given that the PWM header doesn’t have a problem supplying the asking current? The fan uses a cable that consists of 24AWG gauges. These are good to go up to 7A at 30°C at this specific length. Suppose I take into account the resistance losses on the daisy-chain connections. In that case, I can assume that the primary connection cable is good to go with up to 8 fans in the daisy chain, but you should keep in mind that 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. This means you will have difficulty finding a PWM controller to support up to three Megacool fans in a daisy chain since they will need 2.25A at full speed. Even with a pair of Megacool fans at full speed, you will be at 1.5A, which exceeds the capabilities of most PWM headers. This is easily solved, though, if you 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 need a capable PWM controller for the 3-pack of Megacools, let’s proceed to the rest. The build quality and performance are top, although the readings I got weren’t close to the claimed ones, mostly in the low and mid-speed speed presets. 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 for optimal performance; hence, the Megacool doesn’t score so well in the normalized noise performance tests. Even at a high noise level, 45 dBA, compared to the Phanteks T30-120, the static pressure is notably lower, showing that the Megacool is mostly for chassis use if you care about noise output.

The Megacool is ideal for users who don’t care about noise output and need the highest possible airflow and static pressure, emphasizing the first. Not many fans can deliver close to 152 CFM at full speed. The remote control functionality is also high 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 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 Phanteks T30-120 remains on top of the normalized fan speed performance, but with noise out of the equation, the performance crown now belongs to the Super Flower Megacool 120mm fan.
