Kaff exhaust fans are dead, thanks to crystal exhaust
Crystal exhaust fans, the type used in the Kaff X5, were a huge selling point for the KEF X5.
With a design that’s as compact and lightweight as possible, they’re more than capable of handling the rigors of the most demanding applications.
And now, thanks in part to a patent filed by a company called Crystalline Engineering, the same fan can now be used to cool even more powerful and more powerful computers.
The company claims that it can produce an exhaust fan that can spin at speeds up to 20,000 RPM and deliver up to a 40W peak output.
The technology has been around for a while, but the Crystallines patent claims that the fan is able to achieve these high speeds because of a new design.
The fan is “capable of producing up to 10 times the power of conventional air cooling systems,” the company explains.
That power is then transferred to the processor by a thermal-pumped, electro-mechanical, high-pressure liquid-air pump.
The pump’s motor is “largely passive, with the rotor only being moved by a small mechanical force,” the patent reads.
“The design of the system makes it very flexible, allowing it to be configured to achieve a wide range of performance characteristics.”
The patent goes on to describe the cooling system as a “highly efficient passive, high performance, and quiet, all-in-one liquid cooling system.”
For a small amount of money, it’s possible to get a fan with high-end features like fans for Intel CPUs and Nvidia graphics cards.
But this design is just about as affordable as you can get.
CrystallINE Engineering’s patent, which was filed in 2016, shows off some impressive hardware and software components.
It also demonstrates the fan’s ability to spin at 30,000rpm, with a peak output of 10W.
That’s a huge improvement over the 20,00rpm fan that KEF originally introduced in the X5 for its flagship desktop.
The patent also shows off a second design, one that can generate a similar peak output with a much lower peak.
The third design, the Crystals X4, also has a similar design to the one shown in the patent, but it has a smaller rotor and uses a liquid-filled air pump instead of the one used in KEF’s new design (though the patent doesn’t give any specifics on how the new design is actually made).
The patent does give a number of details about how the system works.
“In the present invention, the system comprises a motor, a rotor, a pump, a cooling chamber, and a heat exchanger,” the document states.
“Each of the components has a different arrangement of its component parts.”
For example, the motor is connected to the heat exchangers via a coil, which is connected via a small piece of copper tubing.
The tubing also connects the motor to the cooling chamber.
The liquid in the pump and cooling chamber then flows through the heat exchange chamber, which passes it through a thermal pad to a heat-pump, which then passes it to a cooling fan.
“Once the heat-passing unit passes through the thermal-expansion unit, it is pumped out of the cooling chambers through a fan,” the filing states.
That pump and fan are designed to be “small, low-noise, and silent,” and the patent also describes a “low-noisy, high power motor.”
The design uses “a very simple, and simple-to-use design,” the application says, which “removes the need for a complicated and complex pump and pump-and-fan design.”
The system also uses a single cooling device, which means that it “will not need any additional components.”
But that doesn’t mean that it’s as simple as it looks.
The Crystals patent also reveals that there’s a thermal gap between the motor and the cooling device that is “sufficient to dissipate the heat from the fan.”
The gap “is provided by a solid surface,” the paper explains, which provides the heat transfer “in a controlled manner.”
The cooling device is “a small, lightweight, high output liquid-cooling device,” which has a “large, low output thermal-coolant” and “a low, very low, high, and high output thermal pad.”
The heat transfer between the two pads “is sufficient to dissipates the heat of the fan,” and “thus, the thermal pad provides the required heat transfer.”
In other words, the cooling pad is what’s keeping the fan from blowing too much heat into the system, which in turn helps it keep its RPM low.
But there’s one major problem: The patent doesn
