Scythe Slip Stream 120 mm Slim (SY1212SL12SL, SY1212SL12L)
The Slip Stream Slim series is the third product from Scythe in this review.
Besides the fan proper, the informative packaging contains a PATA power adapter and screws.
These fans are manufactured in China and come at a recommended price of $10.8. The Scythe Slip Stream 120mm Slim has a 2-year warranty. The series includes four models, two of which are going to be covered in this review. The other two will be discussed in our upcoming report.
These fans are different from ordinary 120mm fans even at first glance.
Each Slip Stream 120mm Slim has as many as 15 small blades. Their number and width are determined by the thickness of the fan, which is only 12 millimeters. The impeller is 113 millimeters in diameter. Five of the fan spokes are 3 millimeters wide; the cable spoke is 8 millimeters. The rotor is 39 millimeters in diameter. The fan weighs 98 grams only.
The blades of this fan are narrow and slightly curved. They have a small angle of attack.
With such a slim impeller and blades, the fan cannot create a high static pressure (Scythe doesn’t declare it, though). Their airflow specs are among the lowest, too. It is only 19.4 CFM for the SY1212SL12SL with a rotation speed of 800 RPM and 24.03 CFM for the SY1212SL12L with a rotation speed of 1200 RPM. The good news is that the noise level is low as well. It is specified to be 19.53 and 21.71 dBA, respectively.
The stickers on the fans tell you their model names and electric characteristics.
The peak power consumption is 0.96 watts for the 800RPM model and 2.04 watts for the 1200RPM model. I got similar numbers during my tests: 0.89 and 1.98 watts. The Slip Stream 120mm Slim cannot boast a low start-up voltage. It is 11.4 volts for the junior model and 8.5 volts for the midrange model. These results are among the worst in this review, actually. The sleeve bearing these fans run on is specified to have a service life of 30,000 hours.
Now let’s see what these very slim fans can show in practical tests:
The results are rather mediocre, I must confess. These fans cannot produce a strong air flow as we might have expected considering their slimness. As for noisiness, the junior model is very quiet while the senior one produces a rustling sound, making it uncomfortable even at low speeds.
