SILENT WINGS PRO 4 - 140mm PWMLEGENDARY SILENCE, EPIC PERFORMANCE AND FEATURES
Silent Wings Pro 4 140mm PWM is the most progressive, performant and versatile fan by be quiet!
- Optimized fan blades for the highest performance on radiators and heat sinks
- Speed switch allows changing maximum PWM speed between medium-speed, high-speed and ultra-high-speed (up to 2400 rpm)
- Small tip clearance and a fan frame with a funnel-shaped air outlet for extremely high air pressure
- Virtually inaudible operation at regular speed
- 6-pole fan motor and fluid-dynamic bearing for less vibration and very smooth operations
- Individual mounting systems for use as a case fan or with a radiator
- 5-year manufacturer warranty
IMPROVED ON ALL LEVELS
Altered blade arrangement for new generation performance
The fan blades are what makes a fan. It is for this reason that the fan blades of Silent Wings Pro 4 140mm PWM have been developed newly from scratch. The new blade arrangement enables a performance second to none for all possible operations. Be it in a case, on radiators or heat sinks.
OPTIMIZED FOR HIGH-END PERFORMANCE
Minimum distance for maximum air pressure
Silent Wings Pro 4 140mm PWM makes for extraordinary air pressure and therefor, significantly increases the system’s performance. The decreased distance between the fan blades and the frame enables an extraordinarily high air pressure. By that, the Silent Wings Pro 4 140mm PWM allows the user to run even the most demanding applications.
SPEED SWITCH
3 speed options for any possible application
The speed switch makes switching between medium, high-speed and ultra-high-speed of maximum RPM levels quick and easy. The Silent Wings Pro 4 140mm PWM alters its application with a simple slide to the right. Medium-speed is suitable for any operation that requires regular cooling performance. High-speed lets the fan spin faster, providing more cooling power. Ultra-high-speed ultimately offers enough rpm to cool even the most demanding hardware in high-end PC builds.
6-POLE FAN MOTOR
The key for virtually inaudible operation when needed
6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 36.8dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed.
3 DIFFERENT MOUNTING OPTIONS
For any purpose
Silent Wings Pro 4 140mm PWM has 3 mounting options in the scope of delivery. The pre-installed radiator corners are specially designed for radiators on which the incomparable performance of this high-end fan completely shines. On the other hand, for chassis use, the anti-vibration mounting is the first choice as they reduce vibrations to a minimum. The plastic mountings round up the scope.
FLUID-DYNAMIC BEARING
For a sustainable operation
The advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours. In addition, it reduces the vibrations significantly and supports the virtually inaudible operation of Silent Wings Pro 4 140mm PWM.
ELEGANT LOOK
Magnificent appearance in all details
The all-black design combined with a high-grade fan sticker makes Silent Wings Pro 4 140mm PWM a highlight in any system. The finely sleeved PWM cable perfectly rounds up the outer appearance of the fan. Not only does the PWM cable look great: its connector can also be plugged in and out with ease, making the fan an eye-catcher and user-friendly alike.

My opinion
Format: Kindle
Let me preface this by saying I really liked the story and the characters however, this book is in desperate need of some sort of editing. It's not misspelled words or formatting, but continuous run on sentences. Redundancies within the sentences. There were a couple of paragraphs that I had to go back and reread 3 or 4 times. Overall, I'd say it was worth the read.

Beautiful
Format: Kindle
I love omegaverses I had looked at this one multiple times thinking it's just another book about cocky rock star guys that let fame get to their heads and there are parts like that so I wasn't 100% off. I started reading the second book and met the fmc Astraea from the first one,after she had a run in with the aphla from the gym.😁 it gave me the push to stop and read book one first and im so glad I did this book was amazing their was so many characters I fell in love with hoping they will find their happily ever after. the guys were great, the plot was 🎯, and the ending had me 😭😭😭. I was wondering how nate could ever redeem himself, and he did. the last scene with him was sad, but I also felt it was beautiful. thank you to the author for making a beautiful omegaverse book that gave me all the feels. now I'm jumping straight into book two.

Knot their Omega
Format: Kindle
It took me a day to really get into the book, there is a lot happening in the beginning of the story. I wish there was more of a time frame because I felt like something’s happened quickly but they were farther away than I thought so that was a little confusing to me. I felt like there was so much happening but also not enough.
As for the story itself I enjoyed it, it was different than other OV I’ve read. Bring the tissues, you will need them. They guys were great, I wish we saw more of Kai and Kenjis relationship. As for Nate…… IYKYK.
I enjoyed this book, my first from this author and look forward to reading about Kamaris story.
Book: ⭐️⭐️⭐️⭐️/5
Spice: 🌶️.5/5

Has Potential, Poorly Executed
Format: Kindle
I really really wanted to enjoy this book and was looking forward to reading it. However there were just one too many convoluted plot points, sentences just did not flow nicely at times, and I was left with a lot of confusion on my end. I think it has the bones of being a great story but seems like it was rushed and I had to push myself to finish the last of the book and was left with an unsatisfying ending. It’s definitely different from other omegaverse novels I’ve read but not for good reasons. I really think it could be great but needs some serious tweaking and editing before I’d read it again.

Secrets, Seduction, and Rockstars!
Format: Kindle
Rockstars, secrets, and off-the-charts chemistry? Sign me up!
Cinder Blaze takes us on a rollercoaster of passion and peril with Knot Their Omega. Blair Vesper, a secret Omega masquerading as an Alpha, strikes a risky deal to tour with Blooming Salvation, a band teetering on the edge of chaos. Enter Icarus Morrigan, the enigmatic manager, and his three complicated and irresistibly sexy rockstars: wild Kenji, icy Kaiser, and fiery Nathaniel.
This book delivers steamy Omegaverse drama, sizzling slow-burn romance, and just the right dash of angst. The tension between Blair and the band crackles like electricity onstage, while the societal stakes add depth to the spicy dynamics.
Short, sharp, and oh-so-sinful Knot Their Omega will have you hooked from the first note!
