Heard the tech a while back (2011), might be a good solution for low profile coolers.

And Thermaltake finally release a consumer product.

Thermaltake -

1U
27mm height!! 27(H)*91.5(L)*91.5(W) mm
TDP 70W

Waiting for some reviews

I remember people chatting about this design here years ago. I thought I remember there being one big flaw to these regarding the thermal design. Can't remember what though. How much power does the motor need to spin that, how much heat will the the motor of the heatsink make in itself? I bet the results won't be anything special. Maybe just enough to get by in circumstances requiring ultra LP cooling.

Really looking forward a 90W and 120W.
Will especially be happy if they fit the DAN A4 case.

First benchmark shoud be finally available soon. price is quite interesting. this one is under 50USD if I remember correctly.

I imagine it will not be great compared to larger coolers like the Noctua L9i, but for truly low-profile (1U) scenarios, it has the potential to be best-in-class.

Is it just me, or dos it look like dust will have a greater effect on this than a conventional cooler? Really I just see this as a potential upgrade from a passive cooler, but can't work out for the life of me how it would compete with an active cooler.

Will it turn your finger to spaghetti if you touch it by accident? or the sata cable blah blah. Not that I have touched my CPU fan, just saying.

The theory behind them is that dust has LESS effect on them, because of a lot of fluid dynamics engineering.

This is the video from Sandia National Labratories, the think-tank who originally designed this cooler:

Nope. The blades are curved away from the direction of rotation. It would cause no more damage than sticking your fingers onto the flat blades of a case fan.

I don't know why all the licenced iterations have the secondary heatsink ring around the blade instead of a larger blade, but I'm guessing it has something to do with either requiring less precision during manufacturing or shielding the corners of the blades from someone touching them. (Even though they wouldn't cause harm anyways.)

Oh man. I've been following the Sandia Cooler for a long time, and am really excited about this. Two different companies (Cooler Master and "CoolChip") appeared to licence the design and then did absolutely nothing with it.

If this has the ability to keep a stock i7 relatively cool, it's going into my Dr Zaber Sentry in a heartbeat. I don't doubt it'll be quieter and better performing than the Cryorig C7 that's the 'default' best cooler that can fit in it right now.

Sandia National Labs: designed the air bearing heatsink/fan combo
Coolchip: Demonstrated (and used to gain seed funding) their own unlicensed copy of the Sandia cooler, but otherwise have no relation to SNL. Supposedly their newer design has been changed enough to avoid litigation.
Cooler Master: First to license Coolchip's cooler, but decided not to go into production
ThermalTake: Second to have licensed Coolchip's newer design for production

...interesting. I did not know that - kind of sad to hear that it's not the real deal, but maybe it's at least a proof of concept that this style of cooler can be sucessful?

If you look for a real 1U cooler it is the best deal you can get.

Until they announce a price and there are actual reviews, you know that's just wishful thinking. If this were a revolution in cooling, then a company would have brought it to market A LOT FASTER than four years after the invention was announced.

and in other news, Biostar makes motherboards again.


How long till the caps fail, I'm taking bets!

Will it work in vertical position?
Is the bearing any good?
The coils being in the impeller part instead of the base confuses me... how is the power delivered? That's a three-phase motor which would need at least three leads with a more complex driver than regular brushless two-phase motors.

Looks like this unit is up on Amazon already. I haven't been able to find any reviews yet.

I am quite confused by the Amazon product page of this cooler.

If you look at the Q&A and the user reviews, there's some that date back to 2014 and 2015. Surely this didn't fly under our radar for 2 years.

Maybe they reused an old product's page? Meaning all Q&A, user reviews, and user ratings on that page are obsolete and irrelevant.

There's two products on that page; the reviews and Q&A are for the "budget" model, which is a bog-standard extruded aluminum heatsink+fan. The Engine 27 should really have its own product page, considering how different they are.

The coolchip and coolermaster demos did not have that "motor noise" like in the sandia cooler video.

I hope it doesn't have that motor noise like in that video.
As they say in the video, that the noise is from the motor WITHOUT a cover, which you are unable to hear when there is a cover ON THE motor. :)

Not stock, both CPUs were delid + liquid pro applied. It cooled the i7-6700 at a stable 1563rpm. He also noted that compared to a heatsink with plastic fins of the same diameter, he could hear a distinctly metal-ish sound, but overall the noise level was quiet.

So, not so good result ? if there is a metalic noise, it might be more annoying than a normal fan noise...

Screw it, I'll buy one. I won't have a chance to test bench it for quite a while, but I'll try my best.

So since the coolers been out, any reviews or tests/bench results out yet?

Yeah, there is a japanese one, and google-translate handles it ok. I can try to find it later, or you can go look in the Dan-case a4 thread :)

Is Thermaltake even worth considering nowadays? Bought a number of their cooling solutions back in the original Athlon days for a project where an entire LAN (16 machines) was built from scratch, and every single one failed within six months. I later read that most system builders of the time considered their components 'cheap junk'. Needless to say I've viewed their offerings with a jaundiced eye since that time.
