ENERMAX Launches the D.F. STORM 3500 RPM, Self-Cleaning Fan

ENERMAX releases D.F. STORM fan, the new flagship 120mm fan which can operate at 3500RPM. The D.F. Storm can generate strong airflow up to 155.08(CFM) and static pressure as high as 11.131(mm-H2O). Furthermore, the high-speed fan includes the latest DFRTM technology for self-cleaning and the patented APS PWM design, which makes this fan an excellent cooling choice for servers, industrial applications or high-performance gaming rigs.

This super high-speed fan employs the Storm-Flow blades specifically designed to be used under extreme conditions. The solid design and the special shape of the fan blades will ensure low-vibration during operation. Unlike other high-RPM fans using two-ball bearing, D.F. STORM utilizes the ultra-silent Twister Bearing technology to deliver silent operation; moreover; its high-quality and heat-resistant components ensure 160,000 hours MTBF, even at high operating temperature.
Exclusive Adjusted Peak Speed (APS) Design to Give 3 Different Speed Ranges
D.F. STORM series is built with the patented APS design which provides 3 different speed ranges to satisfy different cooling needs: Performance Mode (1500~2200RPM), Overclocking Mode (1500~2800RPM) and Turbo Mode (1500~3500RPM). With an APS control switch, users can adjust the speed modes much easier; the LED indicator at the back of the fan can reveal the speed mode. Within the selected RPM range, the fan is controlled by pulse width modulation (PWM). The APS design gives users greater flexibility in choosing the preferred fan speed to cool their rigs.

Innovative Dust Free Rotation (DFRTM) Technology to Remove Dust
The DFRTM technology can help reduce the dust that gradually builds up throughout the time and extend the intervals for fan's cleaning and maintenance; this mechanism also helps prolong the product lifetime.

Availability & More Product Information
D.F. STORM fan will be available to cool your heavy-duty rigs in June.

So 8 months from now

Almost as bad as movie teasers.

This was the most intense trailer for a fan ever.

Their fans are good (I have Twister Pressure) performance wise, but this supposed easy disassembly of the rotor just doesn't work. I nearly destroyed my fan trying to take the rotor out. I've pushed it like shown on the image and it pulled whole PCB with motor out of the frame. And then it started rattling because the fan wasn't centered properly anymore since glue holding it let loose. Same on TWO such fans!

The APS system is cool though, 3 fans in 1, so you don't have to buy different versions of it if you one day have silent setup, but next month you need best cooling regardless of noise. Nice to see they moved the control out of the frame to external controller. Was a bit annoying flipping the integrated switch with a screwdriver and even that only when fan was stopped (depending on position though).

The reverse spin cleaning cycle isn't all that new, we've seen it on some graphic cards before, but still, a nice addition.

what kind of noise does it make?

1500rpm minimum ? Pass.
The 120mm fans I use don't even have a 1500rpm maximum fan speed and are already loud at that speed. These must be targeted at enterprise server usage but marketing seems to think it fits with consumer applications.

did you remove a mini magnet under sticker before try remove blades ?
sounds like no :-/

No one ever said anything about removing the sticker. Why would you anyway, that's how you void your warranty on most products!?


I've done it like this guy and whole motor assembly was torn from the frame.

It's a PWM maximum. Depending on the switch state, it changes the fan speed range, not fixe speed. It can still run silent at idle, but under load it scales to set max speed. But again, if you made a lazy fan curve, it'll take longer to go full set speed. But it's there and available. If no curve is set, then it's linear from 0-100% fan speed, where APS set state defines what's the 100% speed RPM.

lol fella, you posted old fan, and here its completely new, with the magnetic bearing wheel, what wee magnet balance your fan and keep it quiet for a long time, and when u want to remove blades for cleaning, you must take a wee magnet from back side in the middle.

An 120mm fan that's silent at 1500rpm seems highly unlikely. Maybe if you're wearing headphones with a game blasting through or live in a noisy environment, but 1500rpm on a 120mm "industrial grade" is not going to be silent. Which is my entire point: the too high minimum speed, not the flexible maximum speed (that's a plus).

The maximimum rpm is 2200/2800/3500, the minimum rpm is 1500.

It's silent depending on fan curve. You can set it to run at only 20% until given sensor reaches excessive temperatures you usually don't encounter. So you have it in quiet, but allow very high mode for fail safe. That's entirely possible. But when it actually reaches 1500 RPM, yes, unlikely, even if it has the best blades and bearings, it's just the air it has to push that makes the noise at that point.

There is no "magnet" behind a sticker thing. Here, my EXACT same fan:

No removal of the sticker. They always just push it out. In my case, trying to remove rotor from two such fans resulted in whole PCB with motor assembly popping out of the frame.

I had twister pressure fans for a while too, the blades popped on and off without issue, but one developed a tick after a while

Shame as they worked well on a reasonably restricted rad

Now this. This I want. More RPM is always useful for benching :D

don't talk if you don't know or you doing it the wrong way!

i told you before its different technologie, here is link you can look at 0:15 can notice a wee magnet, sure you can pull out blades without removing a magnet but nobody guarantee you don't broke it and later your fan don't work loud/noisy

Enermax never mentions a magnet needed for blade removal. There all snap off.

Also that "magnet" your referring to @ 0:15 is part of the bearing not a locking mechanism for the blades.

At 0.26, why is it vibrating so much?

Well, I know, but I still have to ask how it made it into the final video...

Fans are so cheap (relative to their typical lifetime) I just buy new ones when they start making noises or something.
This looks like useless gimmick.

So what is the minimum rpm of these fans if the manufacturer's specs are wrong ?

The specs are not wrong, it's just that they are only specifying max fan speeds. Minimum RPM is usually the starting voltage. APS set mode is their MAX. I think my Twister pressure could go as low as 600 RPM. Or was it 800 RPM. Not sure, I just know they were super quiet at that point and hardly spinning :D

I have a lot of trouble with dust in my PC room due to pets, so I'd be interested in trying these. The pressure rating looks good on these too. I'm set for a while with Noctua's I put in not long ago, but I'll probably give these a try sometime.

Agreed! It was like the premiere of a AAA game. :wtf: Your comment gave me a good laugh.

I've become a fan junkie in my fan research. I've got stacks of them, always in search of the right amount of airflow versus noise. I've learned A) RPM's don't necessarily equate to noise, and B) Enermax makes among the top fans for cooling and quiet. It's all in the motor and the fan shape/pitch.

The fan he posted in the first video has the exact same magnetic twister bearing as this current one, and the same method of removing the fan blades. so it applies. This bearing is nothing new for Enermax.

No mate, the fans minimum RPM is 1500, the maximum is 3500

that means a pwm range of 1500-3500 rpm +-10% probably

Actually, with their fans, that switch is a speed range for the maximum, depending on PWM needs to fight heat..
