Why do find 'MOST' distressing the rush to type? It is known problem solving technique to introduce 'layman' into the process with views on obtaining unorthodox/fresh problem apprach...
I followed your priceless advice and read through 3 different pieces on thsi technology and last one was quite decisive in forming of my opinion of it.
This site showed working example of such a device ( I skip over the theory here since I could not be asked to retype all of this stuff here...). Its working characteristics proved to be enlightening. Performance of 450w from 80x80mm base size device was achieved at 40C temp difference which translated into CPU temp means 60C operating temp with 20C ambient... <- point #1
Imo this technology is another way keep heat pipes going by finding a way of decreasing diameter of a heat ppe and therefore being able to cram more of them into smaller foot print... <-point #2
Lastly I still find distressing thought of having no cooling periods (bubble time) corresponding in time with heat flux spike and with such high operational temp it means potential CPU burn-out...
Hence I find constantly evaorating classical heat pipe a better solution here.
3mm dia classical heatpipes in large numbers with low temp boiling point liquid should offer better performance.
Nice find anyway
