Coolink SWiF2 1201
The Coolink SWiF2 1201 is a rather new model. It is shipped in a small cardboard box with a cutout in the face side through which you can see a part of the fan. You can read the specs of all SWiF2 series fans from the back of the package, the specs of this particular model being highlighted in yellow.
The fan comes together with soft silicone pins of an acid-green color and with four self-tipping screws. The Coolink SWiF2 1201 is manufactured in China and has a recommended price of $11.9. Its warranty period is 5 years.
The Coolink SWiF2 1201 differs from the other tested fans in having as many as 11 blades. The impeller is an eye-catching yellow-green color. The frame is matte black.
The impeller is 111 millimeters in diameter. Three of the fan spokes are 5 millimeters wide; the cable spoke is 8 millimeters wide. The rotor is 41 millimeters in diameter. For the fan to perform well with so many blades, the Coolink engineers had to make them smaller and denser and increase their angle of attack as you can see in the photo:
The fan’s frame doesn’t differ from the other fans’ and has two ribs on the interior surface. The speed, air flow and noise level of the SWiF2 1201 are specified to be 1200 RPM, 55.4 CFM, and 18.2 dBA, respectively. The manufacturer doesn’t specify the static pressure. The fan weighs 145 grams.
There is a rather informative sticker on the fan’s rotor:
According to this information, which agrees with the product specs, the SWiF2 1201 has a peak power draw of 1.68 watts. My measurements yielded 1.56 watts. The start-up voltage is declared to be 7 volts but both my samples of the Coolink SWiF2 1201 could start up at a low voltage of 3.3 volts. The fluid dynamic bearing of this model is expected to serve for 150,000 hours, which is most impressive for this type of bearing. The 3-wire sleeved cable of the fan is 400 millimeters long.
Considering its specs and original impeller, the Coolink SWiF2 1201 should deliver high performance. Let’s see if it is really so.
The Coolink SWiF2 1201 is subjectively just as good as the Cool Age Silence Fan 120DX2 in terms of noisiness, although it is formally louder according to the numbers. It is quite comfortable up to 1010 RPM and quiet up to 880 RPM. On the other hand, this model cannot produce a strong air flow, being just average in this parameter.
