The decreased distance between the fan blades and the frame makes it possible. By that, the Silent Wings 4 120mm PWM high-speed allows the user to run even the most demanding applications.
DIFFERENT MOUNTING OPTIONS
For any purpose

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 31.2dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated
in mid-speed.
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 4 120mm PWM high-speed.

Excellent pampers
Size: Size 6, Unit Count: 50
Something I really like is that they absorb very well and help prevent leaks, even overnight. The material is soft on the baby’s skin and so far has not caused any irritation. In addition, the adhesive tabs are strong and allow for an easy adjustment, helping the diaper stay in place even when the baby moves a lot.

Best for a blow out!
Size: Size 5, Unit Count: 58
We loved pampers for months then my baby turned 7 months and started having blow outs bc he was so mobile. Huggies little movers fix that problem! Nice and thick, completely leak proof by the legs and up the back, nice and soft!

Great diapers, just a couple small issues
Size: Size 4, Unit Count: 150
Size 4 have been super reliable for my baby. They fit well, don’t sag, and handle active movement without leaking. The absorbency is great for daytime and short naps. My only minor complaint is that they can be a bit pricey compared to other brands, and occasionally the tabs feel a little stiff. Still, otherwise it’s a dependable diaper that I would definitely recommend

Reliable Fit for Bigger ToddlersI’m
Size: Size 7, Unit Count: 88
These diapers are great quality and hold up really well for active toddlers. My son has always had thicker legs, and these have suited him really well without being too tight or causing irritation. He just turned two and is already in a size 7 (almost an 8), so sizing up has definitely been helpful for comfort and better coverage for US. The absorbency is consistent, and they stay in place—overall a very dependable choice.

What a wonderful treat, loved by our very fussy dog!
Our very fussy Havanese absolutely LOVES these sticks! I had to find a new product after the USA-made chicken wrapped rawhide sticks were no longer available. It is very difficult to find a quality product made in the USA & while these are made in Cambodia, they seem to be made under very strict standards. I was also impressed that this co. claims it has never had a recall of their products. I also relied on the many, many excellent reviews of past customers. Our Teddy gets a stick every morning & then will wait by the pantry to get an additional 1 or 2 or more throughout the day! He usually does not eat the rawhide, just chews it up a bit. He is in love with these!! He also has a sensitive stomach & these have never bothered him one bit. His teeth are also quite clean from using these!
