Antec TriColor 120mm

TriColor 120mm fans are installed by Antec into their system cases and are also available as individual products. The fan comes in a transparent plastic blister wrap with a paper insert.

The product’s key features and specifications are listed on that insert in three languages. Included with the fan are a PATA power adapter and four self-tipping screws.

The Antec TriColor is manufactured in China and costs $15. Its warranty period is 1 year.

The frame and the 7-blade impeller are made from transparent plastic. It’s even quite hard to spot this fan against a white background.

 

The impeller and electromotor are 111 and 45 millimeters in diameter, respectively. Three of the fan spokes are 4 millimeters wide; the cable spoke is 7 millimeters wide.

The impeller blades lack any distinguishing features. There are two ribs on the interior surface of the frame. The gap between the frame and the impeller is no larger than 2 millimeters.

The speed of this fan can be regulated by means of a cable with 3-way switch.

You can set the speed at 1200, 1600 or 2000 RPM to get an air flow of 39, 56 or 79 CFM at 25, 28 or 30 dBA of noise, respectively. The start-up voltage, power consumption and bearing type are not listed among the product specs. Of course, I could not learn the type of bearing without taking the fan apart, but I did measure the other two parameters. The start-up voltage of my Antec TriColor 120 was 3.9 volts and its peak power consumption was 3.2 watts in my tests.

The 3-wire cable of this fan is 470 millimeters long.

There are LEDs built into the corners of the fan frame.

The highlighting cannot be turned off but I don’t think that people will buy this TriColor for using it without its highlighting, especially as it is quite beautiful.

Here are the test results for this fan:

The Antec TriColor performs alike to the above-discussed Akasa Viper, except that the bottom level of speed and noise is somewhat higher with this model. The TriColor doesn’t produce any unwanted additional sounds. So, it is just yet another average fan.

Arctic Cooling ARCTIC F12 Pro PWM

The ARCTIC F12 Pro PWM from Arctic Cooling is a copy of the ARCTIC F12 Pro TC covered in my previous review. The key difference is that it supports PWM-based speed regulation as is indicated on its packaging:

Besides that, the ARCTIC F12 Pro PWM has a top speed of 1500 RPM, which makes it eligible for the second part of this large roundup. The bottom speed is 400 RPM. The max air flow is specified to be 57 CFM at a noise level of 0.5 sones. The information on the sticker is the same as that of the ARCTIC F12 Pro TC. According to my measurements, the ARCTIC F12 Pro PWM starts up at 4 volts and consumes no more than 2.6 watts. The recommended price of this product is $9.5.

This model having no design differences from the ARCTIC F12 Pro TC, let’s move on right to its test results.

The ARCTIC F12 Pro PWM surprised me with its subtle, yet audible rattle. It was only at near-maximum speeds that the rattling sound got lost in the noise of the air flow. Perhaps this was a problem of my particular sample of the fan (unfortunately, my second sample had lost one blade of its impeller during transportation) but I don’t like it anyway. The ARCTIC F12 Pro PWM doesn’t show anything exceptional in terms of air flow which might be expected from a frameless fan with a rated speed up to 1500 RPM.
