Scythe Gentle Typhoon High RPM

We’re already familiar with Scythe’s Gentle Typhoon series. Today, this Japanese firm is represented in our review with three high-speed Gentle Typhoon High RPM models.

Scythe traditionally ships its fans packed into transparent blister wraps with a paper insert inside.

This packaging is more robust than cardboard and also allows examining the fan without taking it out of the box. Technical specs are also listed on the packaging, though.

The fans come with a minimum of accessories: four self-tipping screws and a fixed cable.

According to the packaging, these fans, like the majority of products in this review, are manufactured in China. However, Indonesia is mentioned on the fans’ own stickers. Each of the three models costs $23. The warranty period is 2 years.

The high-speed versions differ from ordinary Gentle Typhoons in having a black frame and a black impeller with additional stiffening ring.

 

There are no visual changes otherwise. The blades are long and curved. The interior of the frame is smooth.

The 7-blade impeller is 109 mm in diameter whereas the motor is 52 mm in diameter. The weight is 216 grams.

The Scythe Gentle Typhoon High RPM series features impressively high speeds. The junior model has a rated speed of 3000 RPM whereas the medium and senior models are as fast as 4250 and 5400 RPM. The specified air flow is 83, 116.5 and 150.1 CFM. Of course, noise is not a priority with such fans but Scythe specifies it at 36.5, 44.0 and 50.5 dBA. The static pressure is not declared, unfortunately. We are curious to know how high it might be at such speeds.

The impeller is reinforced with a ring that goes near the ends of the blades:

The bearing hasn’t changed. It is still a manually-balanced dual ball bearing with a guaranteed service life of 100,000 hours (or over 11 years of continuous operation). The sticker on the motor provides information about the fan model, electrical specs and country of origin.

  

The power consumption is high. The junior model needs 2.64 watts, the medium model needs 6.72 watts and the senior model, as much as 13.7 watts! That’s why the fan is only connected to a PATA power connector. There is a separate cable for speed monitoring. Each cable is 300 mm long.
