I'd have to query how that isn't a fan... :(
(Stealing definition)Has blades, has rotation, has air current :) Kind of a fan to me heheQuote:
1.An apparatus with rotating blades that creates a current of air for cooling or ventilation.
I thought it was going to be powered by the heat coming off the cpu die.
From what I remember these heatsinks also selfcleaned/did not get filled with dust thanks to the rotation. It also was not actually attached to the chip so there was no thermal meium to wear out as it traveled microns above the chip surface. Not sure how well these would deal with shock/orientation change when some little dinkus kicks over the workstation but could still be useful if just for the perhial technologies.
Anyone remember this?
I thought it was a prett cool piece of engineering, though I'm not sure it would work with todays 300w+ graphics cards...
I've seen this before - one issue, what about vertical mounting?
Back then, it was very difficult to build or buy a Pentium 4-based PC that was silent or very quiet. Now it's really easy and significantly cheaper. :)
Not related to heatsink / fans etc but found this :
Thermaltake’s Xpressar PC Case Uses Actual Fridge Compressor For Cooling | Gizmodo Australia
PC Case using fridge cooling instead of water or the generic / universal heatsink / fan etc
This technology seems a complete waste to me. Fans are extremely cheap to buy and/or replace and this to me is going to cost considerably more.
There will be fanless PCs in future with reasonable sized heatsinks. For example, if you had 64 cores all running at 500MHz - this would deliver excellent performance yet create little heat. There would be so many idle brains doing little or nothing at all. We just don't need technology to re-invent the fan.
Asetek actually released a refrigerated PC case eight years before Thermaltake did. It was called the Vapochill. The XE II model from 2005 is pictured below.Quote:
A CPU base makes contact with the processor (LGA775, LGA1155, LGA1156 supported), which conveys heat to a side panel via four copper heat pipes. All six panels of the case are made of thick aluminum sheets, some of which are ridged to increase surface area for heat dissipation.
Vapochill rocked - but you can tell the age of the case by the curves and the strange looking slot in the front for a floppy drive ;)
The Zalman one was 100% silent too - actually built one thanks to one of those friends with more money than sense. He saw it at ECTS god knows how long ago and decided he needed it.
