Next Generation CPU Coolers

[bailojustin]

What does everyone think about the next generation of CPU coolers I think will personally take the market. They are Impeller fans, one such as the Sandia Cooler. I personally am very excited. A heat sink that does not gather dust, and spins on a Airlayer that is microscopic for the best heat induction from cpu to heatsink.
Also just the fact that it pulls air in from the top of the cpu directly onto it, then using the force of gravity, swings this air through the curved fins by spinning as amazingly high speeds. The cooling potential for this can be limitless. it would be incredible because of the amount of air that is moved would cool every single thing around it including vrms, and ) dust buildup due to spinning at such a high velocity.

What are your opinions on Impeller Cpu Coolers?

That design has been a work in progress for over three years.

My main skepticism about it is the very high machining precision required to make it work right. If the mating surface between the base plate and rotor is not perfectly flat, they will touch and this will cause vibrations. If the rotor is not perfectly balanced, it will vibrate, cause noise, possibly touch the base plate and create further problems.

The design might not be suitable for handling by the average Joe.

This tech has been around for a few years now (published in 2011, and hasnt been updated since 2014), while it does seem cool in concept, its not viable.
They do not perform as well as normal heatsinks do, struggling with high TDPs, and are dangerous.
Think about it, what happens if that impeller gets off balance? That is a large piece of metal to have spinning at high RPM near sensitive components. Even if it dosent fly off, the vibrations alone could damage the motherboard.
Impeller coolers are also nasty loud. (High pitch)
Plus that level of machining required wont be cheap.

Its been around for a long time, its only a matter of time before someone looks at it and realized what they have to do to make it work. what if they were to transfer the heat over a 5mm gap through induction, Is this possible to do, or if they created a magnetic field that secured the impeller perfectly in place. we have done that before to hold neutrons in empty air using penning traps, mauybe that same idea can be used to position the impeller and keep it perfectly alligned?

It has been around for a while, and its intellectual property. Unless the original inventor makes it work and pushes it to sales, nothing will come of it.
As for something holding it level. The magnet idea is an interesting concept, but then again, would you trust a magnet on your processor?
Adding onto that, what keeps the leveling device level as well? If it gets misaligned then the whole thing goes off balance.
