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.

Who Says Pregnancy Pillows Are Just for Pregnancy?
Size: 57 Inch, Color: Light Grey, Size: 57 Inch, Color: Light Grey
I bought this pregnancy pillow even though I’m not pregnant, and I have zero regrets!
This thing is incredibly comfortable and provides support in all the right places. Whether I’m sleeping, reading, listening to an audiobook, or just relaxing in bed, it helps me get comfortable and stay comfortable.
I love being able to hug one side while supporting my back with the other. It feels like being surrounded by pillows without having to constantly rearrange them throughout the night.
The only downside is that it takes up a decent amount of bed space, but honestly, that’s a sacrifice I’m willing to make. My family may disagree. 😆
If you’re considering this pillow but aren’t pregnant, don’t let the name stop you. Comfort is for everyone!

Pretty, but very practical.
Size: Full, Color: Mint Green
The color was exactly what I expected from the photo. It arrived in an unbelievably small package, but expanded quickly once I opened the bag. I waited the recommended 24 hours to be sure it was done. I am pleased that the length is a perfect fit, and I like that it comes up to the back of my neck when I'm sitting in bed. It is a bit softer than I originally imagined, but not so soft that I feel like I'm sinking through it. It's very pleasantly supportive. The fabric is like a soft ribbed corduroy with piping along the outer seam. It looks nice. Both ends have a pocket that is barely noticeable, but is the perfect size to keep your phone close by. I'm temporarily homebound and spending a lot of time sitting in bed, so I'm very glad I invested in this pillow for comfort and convenience. If you ever have trouble with pillows working their way under the edge of the headboard, and into the dusty space between the headboard and the wall, consider this problem solved.

Measure your bed and space, I did and ordered the perfect fit!
Size: Queen, Color: Navy
Love this wedge pillow. I bought it for our boat stateroom bed. It fits perfectly as beds on a boat are always odd sizes. It is very comfortable allows me to sit up in bed to read. Also keeps our bed pillows from sliding back. Good quality, color and size.

Comfy, Supportive, and Great for Lounging in Bed
This wedge-style headboard pillow has made sitting up in bed much more comfortable. The shape offers full upper-back support, with just the right amount of firmness to keep you propped upright without feeling stiff. It’s especially helpful for reading or watching shows in bed, and it stays in place well against a flat headboard.
The purple color is rich and vibrant in person, and the removable cover is soft to the touch with a smooth finish. We really appreciated that the cover zips off easily and can be machine washed—it held its shape and color after laundering. The pillow also has a nice weight to it, so it doesn’t feel flimsy or slide down easily.
This is a great addition for anyone who likes spending time sitting up in bed, whether for reading, working, or relaxing. It also doubles nicely as a decorative accent when the bed is made. The quality feels solid, and the size works well across the width of a queen bed without overwhelming the space. Id say it is ok for the price. It does retain warmth though

Thick, Supportive, and Cozy for Reading or Nursing
Size: Full, Color: Olive Green
This wedge pillow has been a great fit on my daughter’s bed. It’s super soft and cozy, and at the same time offers great support for sitting up in bed. The pillow is nice and thick, so you don’t sink into it — perfect for reading, studying, or lounging without needing multiple regular pillows.
I tried it out myself and was surprised at how well it also works as support while nursing an infant. It props you up at just the right angle and feels stable without shifting around.
The removable, washable cover is a big plus, and the olive green color is subtle yet stylish. I’m impressed enough that I’ll either be purchasing one for myself soon or adding it to my Christmas list.
