Deepcool UF120

Next goes the UF120 model from Deepcool. We tested the UF140 in an earlier review and now it’s time to check out its 120mm cousin. The boxes of both models are designed in the same way. You can find an installation guide, a list of accessories, and performance graphs of all the fans in the series on the paper insert.

The accessories are four long silicone pins, a user guide, a PATA power adapter, an extension cable, and a cable with two soldered-in resistors for lowering the speed of the fan:

Like the entire Deepcool UF series, the UF120, being a clone of the Alpenföhn Föhn 120 Wing Boost in exterior design and internals, has a beige frame and a blue impeller fastened on four spokes:

 

The impeller and electromotor are 111 and 40 millimeters in diameter, respectively. Three of the fan spokes are 5 millimeters wide; the cable spoke is 8 millimeters wide. The weight of the fan is 172 grams.

The fan frame is not plastic, as usual, but an elastic vibration-absorbing material. Its interior is smooth to reduce noise.

The impeller has 9 blades with three notches on each which are meant for aesthetics only. The speed of the fan is PWM-controlled within a range of 500 to 1500 RPM. The maximum air flow is specified to be 66.3 CFM; the noise level is 17.6 to 27.8 dBA. The static pressure is not specified.

The sticker on the motor is not informative at all. You can only find out the fan’s electric specs on its box or at the manufacturer’s website. The start-up voltage of the Deepcool UF120 is declared to be 7 volts but my sample started up at 5 volts. The power consumption was 1.44 watts in my tests, which is lower than the specified 1.56 watts. The dual ball bearing of this fan is rated for 40,000 hours. That’s not long for this bearing type, I must say. The 3-wire sleeved cable is 420 millimeters long.

Now, here are the test results of the Deepcool UF120 and Alpenföhn Föhn 120 Wing Boost which are both one and the same fan, actually.

Although the Alpenföhn Föhn 120 Wing Boost and Deepcool UF120 seem to be clones, differing only in their exterior design, they do have different test results. The Föhn 120 Wing Boost has a linear correlation between noise and speed whereas the UF120 is not that stable, changing its noise in sudden jumps. I should add that both samples of the Deepcool fan that I tested behaved like that. These results might be due to some differences in the electronics, but I’m almost sure the Alpenföhn and the Deepcool have the same electronics because they have the same start-up voltage and power consumption results. So, these fans are twins externally but behave differently.

Delta FFB1212EH

Delta FFB1212EH is the most powerful fan in this test session. It comes without any packaging and accessories. The manufacturer may have decided such luxuries unnecessary or this model may be just meant for OEMs. The fan is manufactured in Taiwan and costs about $30. Its warranty period is 1 year long.

The Delta FFB1212EH measures 120x120x25 millimeters and this is where its similarity to ordinary fans ends. Just take a look at it:

 

We’ve got a completely original fan here with a large 65mm electromotor, 11 slim blades and 11 spokes which are curved in the direction opposite the blades. This must be meant not only to optimize the air flow but also keep the impeller firmly fixed at high speeds. The impeller is 114 millimeters in diameter.

The fan’s brutal appearance is emphasized by its black frame with two edges on the interior side.

The Delta FFB1212EH is the second heaviest model in this review at 257 grams.

The speed of the fan is as high as 4000 RPM. No wonder that the Delta FFB1212EH is specified to consume almost 21 watts of power. It is connected to a PATA power plug only.

There is a separate cable for monitoring but my controller wouldn’t read any data from the sensor for some reason (it would report 0 RPM all the time). Using adapters, I managed to connect the Delta FFB1212EH to the controller to change its speed. The air flow of this fan is 150.3 CFM and its noise level is 56.4 dBA. Both numbers are the overall highest for this as well as the five previous reviews about fans published on our site.

The voltage and current parameters are indicated on the sticker:

The Delta FFB1212EH consumed less during my tests than specified: no more than 12.3 watts. This is the highest power consumption among all the tested fans, though. The fan cables are both 330 millimeters long.

Let’s see what the Delta FFB1212EH showed in my tests:

Well, there is nothing to comment upon. The Delta FFB1212EH has the highest noise level and delivers the strongest air flow in today’s test session.
