Coolink - the cool look

Maybe the distributor isn’t angry about the following sentences, as I’m writing them strongly in the past tense. So the truth is that Coolink fans have shown me a pretty confusing picture so far. There were good ones among them, and they were bad, even very bad. Then, as the years passed, the very bad ones were absorbed, and the bad ones became at least mediocre, and the really tempting pieces to buy appeared next to them. Because of this, I was curious to see how the new release would work.

As for the boxes, I noticed that the design had changed. The second thing that caught my eye was the middle of the fans peeking out the windows of the boxes, which was quite different from the usual design. I resisted the temptation and instead of quickly disassembling it, I visited the manufacturer’s site to see what pieces came from this new series. Here is the table!

As you can see, the new venti comes in three versions. Two of these have a fixed speed and the third is adjustable, although this is not what we set, but the PWM control. Air transport data is not outstandingly good, but it is among the better. In contrast, the amount of noise given is quite amazing, I will be wondering what the reality is. I hope I don’t have to despise any of the aerators. 🙂

It's time to break up!

Not only the fan comes out of the boxes. We get four screws for fastening, and what’s a great pleasure, we also get four silicone brackets to avoid any resonance that can occur during screw fastening.

There are 92 millimeters…

The turbine works with eleven blades. The profile of the blades is not unusual, at least when looking at the part not towards the center of the rotor. Here it appears that when connecting to the middle part, we also find an extra edge.

If you already have a fan, turn it on! As I wrote above, the noise data raised a little doubt in me, but after turning it on, I had to realize that there was no basis for that. The fans run in complete silence.

The manufacturer writes about his product: An all-new, innovative fan with eleven blades, a huge step forward in terms of noise efficiency. SWIF2's 120mm fans combine the benefits of exceptionally quiet operation, superior performance, and unique colors. The new hydrodynamic solution guarantees quiet operation and a longer service life, with a 60-month warranty.

… And also in 80 mm versions

Sounds good? Well, all your words are true! Liquid-bearing fans were pioneered by mowers, but as time goes on, the technology is becoming cheaper and cheaper, so it’s perhaps not surprising that Coolink now lives with it as well.

After turning it on, the first thing that appeared was that nothing appeared. The shovel began to spin, the wind coming out of it, but that was it and nothing more. Bearing sound is essentially zero, no vibration at all. I've heard a lot of fans before, and it happened many times that the crackling and knocking of the bearing could be heard from its otherwise quiet spear. Well, that doesn't happen with hydraulic bearings at all. I don’t know if this silence and performance has anything to do with carving the shovel profile, but it’s also irrelevant as the end result is perfect!
