I’m curious. This thing apparently doesn’t like to have fans on the output side to push hot air out… What if you didn’t have fans mounted on the cooler and ONLY had bottom to top airflow? Or the inverse, for that matter.
I’d be interested in this sort of cooler for more server applications, and it’d make sense to me to set up ducting for that in the case.
Anyone seen these used yet BTW? Are they on sale?
Haven’t watched the video, but aren’t thermosiphons just heat pipes which depend on gravity for circulation?
They aren’t heat pipes. Its more like a cup with a loop attached and some magic buffoonery to make it go in one direction. Its pretty cool actually. I hope these become normal soon.
Reminds me of that all in one AIO water cooler / block pump from cooler master. I was excited about that, then it turned out it sucked.
My guess is that the fan arrangement affects how well it’s able to transfer heat to the cooling liquid. Less heat, less convection, and so on.
And yeah, they’re slightly different. According to the wiki page on thermosiphons the difference is that thermosiphons rely on convection where heat pipes have a wick and circulate through capillary action. My point was that since heat pipes are pretty standard on heatsinks these days I wouldn’t expect this to act too differently than a “normal” heatsink of about the same size and surface area. Still cool though.
Except this IceGiant cools BETTER than a WATER COOLER. Better than a Freezer 50.
No they go on sale in December. The unit Linus reviews was a prototype. The production version is a bit less chonky but equal or better in performance (as claimed by icegiant) as they increased the fin density among other things to make up for the decrease in size.
