120mm Fan #80 - Corsair ML120 Pro:
So, here we are with Corsairs latest cooling product, the ML120 Pro. Corsair claim to be a jack of all trades with the ML120, and they're not far off. To start with, these are pricey units, and often cost more than competing products from Noctua and other premium cooling fan manufacturers. The price should stabilize in the coming months as the market self-adjusts.
The key takeaway here is the Magnetic Levitation bearings, or so they claim. I'm not a bearing technician myself so I wouldn't be able to tell you if they make a difference or not. What I can tell you, however, is that they are very quiet at ~1150 RPM using a 5V adapter -considered by me to be the sweet spot for these fans. Build quality is excellent and the fan looks just right. They are fairly heavy at 214 gram per unit. I'm guessing the mag lev system has something to do with it.
Now, I usually
never test fans with hardware that are not provided in the box, but given the hype and the high-profile launch, I couldn't just let them loose at maximum RPM (~2400) and call it a day. I used two home made 5 and 7V molex adapters to reduce the RPM for a more realistic usage scenario. I couldn't register RPM using a 7V adapter but I suspect it to be around the ~1700 RPM mark. With the 5V adapter, ~1150 RPM is attainable which happened to be the sweet spot for the ML120. Corsair Claims 400 to 2400 RPM PWM range which is fine, but I doubt anyone would run any 120mm fan at anything bellow 600-800 RPM as these units are nearly inaudible at 1150 RPM. Still, good to have the option.
In push, ML120 Pro is mostly untouchable by fans with similar performance and noise level. In pull, it just lags behind the NF-P12 with almost identical sound levels when a 5 or 7v reducer is used. In push/pull, it's pretty much tied with the P12 for the top spot. The efficiency is really good.
Overall, this is a pretty decent product. At 25 dollars MSRP, they are fairly expensive, but they are the closest thing to match the legendary NF-P12 in my tests while providing better aesthetics and operational capability.
