Performant, Progressive, QuietPure Wings 3 140mm PWM high-speed are the perfect addition to demanding PCs with extraordinarily high performance and progressive features such as a speed-regulating closed loop motor.
Innovative closed loop motor keeps the rpm no matter the resistance
Optimized fan frame for outstanding performance on radiators
Newly designed fan blades and re-arranged angle for extraordinary air pressure
Pure Wings 3 140mm PWM high-speed can be operated with very low minimum rpm for very quiet operation
Long life rifle bearing gives an operating lifetime of 80,000 hours
Product conception, design and quality control in Germany
INNOVATIVE TECHNOLOGY
Closed loop motor for persistent rpm
Pure Wings 3 140mm PWM high-speed features a closed loop motor. This technology is comparable with the cruise control in cars. When working against resistance, for example a fan grill or radiator, fans spin slower as a result. The closed loop motor technology constantly monitors the current fan speed and increases it to the target rpm, if necessary. As a result, Pure Wings 3 140mm PWM high-speed always operates at the desired speed, no matter the air resistance.
OPTIMIZED TO THE MAX
For unprecedented air pressure in its class
The fan frame outlet is newly designed to minimize air leaks. This benefits especially the radiator performance of Pure Wings 3 140mm PWM high-speed. To reach even higher performance, the fan blades are optimized as well: Their angle is adjusted to achieve even more air pressure, adding up to the extraordinary performance of Pure Wings 3 140mm PWM high-speed.
FOR RADIATORS AND HEATSINKS
Fan blades optimized for high pressure
With a remarkably high air pressure of up to 2.44mm/H2O, Pure Wings 3 140mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The 9 airflow-optimized fan blades provide enough air pressure to make this fan work great even in demanding configurations.
ICONIC DESIGN
Streamlined look makes it an instant timeless classic
Pure Wings 3 140mm PWM high-speed trims all the fat. Every part and single detail contribute to the functionality and uncompromising performance. This has also been considered in the design of the fan. All outlines and angles serve a purpose, making Pure Wings 3 140mm PWM high-speed a timeless classic and elegant addition to every gaming PC.
RIFLE BEARING TECHNOLOGY
Makes Pure Wings 3 a long-lasting companion
Pure Wings 3 140mm PWM high-speed is built to last. With the proven rifle bearing technology, on average, this fan offers a lifespan of 80,000 hours.

Finally sleeping through the night without waking up drenched
I was dealing with night sweats almost every night. Waking up overheated, flipping my pillow over constantly, just uncomfortable and restless. It was starting to mess with my sleep in a real way.
Since switching to this cooling pillowcase (and pairing it with a cooling blanket), it’s been a completely different experience. I’m actually staying cool through the night and not waking up soaked or irritated.
The fabric feels cool to the touch right away and doesn’t trap heat like a regular pillowcase. It’s smooth, comfortable, and still feels good after washing. Not stiff or weird like some “cooling” materials can be.
Is it magic? No. But does it noticeably reduce overheating and help you sleep better? Absolutely.
If you run hot at night or deal with night sweats, this is one of those small upgrades that makes a big difference. I wish I had bought it sooner.

so far so good
I was surprised at this pair of pillow cases only because the material seemed impossible to be cooling - it's that weird polyester blend. So far I have not awoken feeling sweaty around my face and scalp. I don't recall what I originally paid but I think it is great value for money! If you are sensitive to out of the box smell, I washed mine first and it didn't impede on the efficacy of the cooling!

It’s like sleeping on a beach in San Vito lo Capo
Italian voice:
I’m a big meaty fella so I put off a lot of heat ya hear. These pillow cases have changed my life. One moment they’re hot and the next you flip them and you’re blasted with a blast of ice cool what it feels like to chew 5 gum feeling capeesh. I would reccomend these pillow cases to even my grandma. If ya wanta get a rest so good that it feels like ya been sleeping with the fishes get these pillow cases, they’re the real deal. Then stop at Pauline’s joint and grab a slice of pizza say Vinnie sent ya. Anyways I gotta go my wife’s cooking up a mean lasgna and we’re gonna watch the dodgers. Let me know how these treat ya I guarantee they will change your life. Vinnie out

Soft "cooling" case.
Yes it is very cool when you lay on it. It doesn't stay cold though. Within a minute or 2 to whatever your temp is.

Great for hair and skin. Great buy.
These pillow cases are great for my hair and skin. They look good, hold up well in the washer and dryer, and the price is great. They are cooling. Of course I wish they could be more cooling, but honestly I'm not sure that's even possible. Great pillow cases. Already bought more for other heads. Would buy again.
