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.

Dog loves the toy
Pattern Name: Funny Faces
I like the egg shaped rubber sqeaker toy. Sqeaker does not last long and the dog wants another to squeak. Have to hold her back as she will go through the bunch it I let her! A lot of fun with our dachshund.

Classic for a Reason — Thick, Reliable, and Actually Works
Size: 8.4 Ounce (Pack of 1)
There’s a reason the German formula of NIVEA Creme has a cult following, and after using it consistently, I understand why. The appearance alone tells you this isn’t some watered-down, trendy moisturizer trying to be cute. It’s thick, dense, almost old-school in the best way — that clean white cream in the iconic blue tin feels intentional and substantial.
The scent is subtle, clean, and nostalgic without being overpowering. It smells like “taken care of,” not perfume. If you’re sensitive to heavy fragrance, this strikes a solid balance.
Now let’s talk performance. This is not a lightweight lotion — and that’s the point. It goes on thick, and you can feel the protective barrier immediately. It’s especially excellent for hands, elbows, knees, and dry winter skin. I use it at night on my face and hands, and by morning my skin feels calm, restored, and noticeably smoother. It’s the kind of moisture that actually lasts instead of disappearing in 20 minutes.
Absorbency depends on how much you use. A little goes a long way. If you apply it generously, it will sit on the skin for a bit — but in a way that feels protective, not greasy. If you warm it up in your hands first and apply moderately, it absorbs beautifully and leaves a soft, healthy finish.
For the price, the value is honestly impressive. One tin lasts forever because you need so little. This isn’t a “reapply every hour” product. It’s reliable, consistent, and does exactly what it promises.
If you want something ultra-lightweight, this isn’t that. But if you want serious hydration, skin protection, and a product that’s stood the test of time for a reason — this delivers.

So good
Size: 8.4 Ounce (Pack of 1)
I am a Nivea loyalist. I love this crème for the winter when the air is super dry, it’s so hydrating for dry skin. I love that it’s the German formal, which makes it better. The tin is huge, you get so much for the price, it lasts so long. It’s so rich and thick and goes on so nice. It doesn’t have a strong smell, more like a clean scent. Also, it goes on thick, you don’t need a whole lot,nor it takes forever to rub in. I warm it in my hands first, just a finger tip amount, rub in my hands and then press it into my face, and then it just rubs in, no white cast. Leaves the loveliest glow. It’s not vegan, if you want a vegan formula, try the Nivea Soft, which I use too, in the summer, when I don’t need a thick formula. It doesn’t cause me to break out, again don’t use too much. I love that you can use it for face, hands and body. It literally is just for moisture. Nothing fancy. The tin is recyclable. I take it everywhere. I keep a little tin in my car, my purse, my overnight bag. My face feels soft and supple even hours after using it. It’s just so lovely.

I loved the Nivea cream; it works really well to hydrate my skin and leave it soft—and best of all, it's fragrance-free.
