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.

Puppy loves it. Well built and fun for her to play with.
Size: 15 in, Color: Retriever
My double doodle mix loved this toy. It is well made and she loves the different texture of the rope. Sadly she has already torn the rope apart and so now it’s just the leather part. This would be the perfect toy for non agressive chewers. Wish the rope lasted a little longer. SPOT is my new favorite company to get her chew toys from now. They’re well built and aren’t expensive like all the other dog toys out there.

Destroyed in under 10 minutes
Size: 9 in, Color: Large Bone
I bought 2 of these toys, one for my 9 year old great dane who isn't an aggressive chewer, and one for my 6 month old puppy who is average.
In less than 10 minutes both were destroyed and my dane managed to swallow a good chunk.
I wasn't surprised when they both had small holes on the ends and started pulling the stuffing out. The stuffing and squeakers were confiscated immediately, but I let them keep chewing. By the time I came back from throwing the insides away, both dogs had chewed the toys in half and my dane swallowed a chunk when he saw me coming. The puppy was going to do the same thing, but luckily we're working on his "drop" command so he was excited enough for the bigger payout and dropped it.
They didn't just come apart at the seams, the whole toy ripped in half making it too easy to swallow. Neither of them are aggressive cheers and the toys didn't hold up at all. A stuffed animal toy would have lasted longer (and has any time I've allowed it). 10 minutes of playtime is probably too generous , but I'm trying to be fair. If I hadn't been right there watching them, they both would have been able to swallow the whole thing in minutes. Definitely not safe for any amount of actual chewing.

The perfect teething toy for a puppy of any size - apparently indestructible!
Size: 9 in, Color: Large Bone, Size: 9 in, Color: Large Bone
I ordered this product for an overly excitable, destructive corgi chihuahua mix puppy, who was teething. He was a foster and managed to destroy, almost immediately, every toy I had on-hand for him, and toys I picked up at the local pet store. I was very concerned he'd swallow parts of toys, which can lead to fatal intestinal blockages, not to mention extremely high vet bills which I couldn't cover as a simple foster mom. When it arrived, I crossed my fingers that the "Seam Protection - doubled-stitched seams with heavy duty thread" would actually add "extra durability." And I was NOT disappointed! The bone shape of the toy would probably fit comfortably in the mouth of any dog or puppy, as you can see from photo #4. What's coolest about the shape of this toy is the pup can sink all of his or her teeth into it, providing comfort for the entire mouth and not just a few teeth or only one section of its mouth at a time. I was much more experienced as a kitten foster mom, and had had similar difficulties finding teething toys for kittens. This toy is thin and light weight enough that I imagine it could provide relief for little kitten mouths, also, but I didn't get to find out, as my little foster pup chose this as his #1 favorite toy and brought it with him to his forever home. I wanted to know how long it would take before he'd destroy it, though (picture 5 he'd had this Dura-Fused bone toy for a few hours short of one week, and the last photo - you'll see he'd not even undone a small portion of the seam!) Overall I would highly recommend this product for teething babies of almost any species. As far as I could tell it is indestructible. Almost seven days of constant gnawing and he'd not even taken one stitch out, created any tear or rip, let alone, gotten close to being able to swallow the squeaker (always a fear!). I imagine months later, he's still been unsuccessful at ripping/tearing this toy at all. I'd gladly buy again should I foster any dog or puppy - the company lives up to its moniker, Ethical Products, because they've produced a no-frills and apparently indestructible squeak toy which I'd have no fears of leaving with a teething puppy unsupervised. Highly recommended!

Good tug toy
Size: 15 in, Color: Retriever
I have a doberman that shready everything in 2.5 seconds. This lasted a few days so was impressed for the cost. Would buy again as he really liked it.

My dog’s new favorite
Size: 8 in, Color: Squirrel
didn’t expect much for the price but my dog actually loves this thing. It’s tough enough to hold up to regular chewing and the leather gives it a nice texture that’s different from the usual plush toys. He carries it around like it’s his prize. It’s not indestructible and if your dog is a heavy shredder it probably won’t last forever but for moderate chewers it holds up way better than a lot of toys I’ve tried. Definitely worth grabbing again.
