NO COMPROMISE SILENCE AND PERFORMANCE
Equally quiet and performant operation
Silent Wings 4 120mm PWM is the fan of choice for all possible operations. Be it in a case, on radiators or heat sinks – Features like the silence-optimized fan blades and the funnel shaped fan frame make Silent Wings 4 120mm PWM a fan that makes no compromises between virtually inaudible operation and high performance.
OPTIMIZED FOR HIGH-END PERFORMANCE
Minimum tolerances for maximum air pressure
Silent Wings 4 120mm PWM makes for extraordinary air pressure and, therefore, significant increases in the system’s performance. The decreased distance between the fan blades and the frame makes it possible. By that, the Silent Wings 4 120mm PWM allows the user to run even the most demanding applications.
DIFFERENT MOUNTING OPTIONS
For any purpose
Silent Wings 4 120mm PWM has 2 mounting options in the scope of delivery. The pre-installed anti-vibration mounting reduces noise-generating vibrations to a minimum. For radiators and heat sinks, the plastic mounting is the first choice. Both solutions have in common that they enable virtually inaudible operation at regular speed.
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 18.9dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated
in mid-speed.
FLUID-DYNAMIC BEARING
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 4 120mm PWM.
ELEGANT LOOK
Magnificent appearance from all angles
Be it as a radiator fan or in the case: Silent Wings 4 120mm PWM always makes a good impression. The all-black design combined with the high-grade fan sticker makes the fan shine in any system. This makes
Silent Wings 4 120mm PWM a high performant and an incredibly
good-looking fan.

Super light and breathable, great for golf
Size: Medium, Color: White Golf Flag
I picked up the Obla Mens Golf Polo Shirt Dry Fit Performance and it’s been a great shirt for the course.
The fabric is thin and stretchy, which makes it really comfortable and easy to move in. It breathes well, so you don’t feel overheated even when you’re out there for a while. Honestly, it’s so light it almost feels like you’re not wearing a shirt.
The pattern looks great too, and the fit is on point, not too tight, not too loose.
Pros:
Lightweight and breathable
Stretchy and comfortable
Nice pattern/design
Fits really well
Cons:
None so far
Overall:
Great golf shirt if you want something light and comfortable. Definitely one I’d pick up again

Attractive shirt and a great value
Size: X-Large, Color: Deep Purple Sunflower
Surprised by the quality. It looks more expensive than it was. It's an excellent value and fit perfectly. It's not boxy or sloppy, but looks trim and professional. The fabric is a perfect weight for Spring and Summer, and the colors and pattern are really nice. It laundered like a dream. With no shrinkage.
This is versatile enough to wear on the golf course, or dressed up with a sport jacket over it.
Great buy.

💲Good Value💲
Size: Large, Color: Pink Colored Dots
Purchased three in large, nice cut and fit, attractive colors/patterns, excellent price point, moderate weight material. From a few feet away these shirts look as good as a $100 polo. Under close inspection they are still nice but not designer quality. That’s fine, as the intended purpose is for golf in the Florida heat. Unlikely to shrink or fade as the material is synthetic. Economical and attractive shirts especially if you don’t care about designer labels. Hope this review was useful/helpful. ☮️

Great shirt for a great price
Size: Large, Color: White Golf Clubs
Love this shirt and ordered and received one more already. Also, lots of patterns and colors. Lightweight, perfect fit and collar holds up nicely. Has an SPF 50 to protect you when you’re out in the sun, even though it’s a lightweight shirt. It is breathable and has the quick dry wicking feature. Price is great. Highly recommend.

Nice overall
Size: Large, Color: Red Flower
Great looking shirt even though collar is not especially stable. Seem like it will be durable. The one thing I have noticed about these moisture wicking shirts is they don’t seem to be especially breathable which leads too more moisture. Good fit, great color and cut just right for a guy who is no longer like Big John, “broad at the shoulders and narrow at the hips” with a tail just right for the untucked look.
