Heat-powered CPU cooler - General

[video=youtube;aeeq-gKX01o]https://www.youtube.com/watch?v=aeeq-gKX01o[/video] [url]http://www.instructables.com/id/Portable-Airflow-Companion/[/url] Of course it won't work very well as a cooler unless there's atleast some kind of other airflow

I was going to comment on the extremely low efficiency of TECs. But this is actually pretty cute.

Daw it thinks it can cool a cpu that's so cute.

That music made it funnier than it should've been

still pretty awesome tech. laughed at ice-cream engine.

Is it stupid to ask how the icecream engine works?

[QUOTE=Aide;47884610]Daw it thinks it can cool a cpu that's so cute.[/QUOTE] It almost can, though (but has almost nothing to do with the fan) [editline]5th June 2015[/editline] [QUOTE=Mango;47885012]Is it stupid to ask how the icecream engine works?[/QUOTE] The cooler is warmer than the ice cream, so the heat goes in the opposite direction

[QUOTE=Mango;47885012]Is it stupid to ask how the icecream engine works?[/QUOTE] There's energy potential in any temperature difference, be it between something really hot and a heatsink at room temperature, or something really cold and a heatsink at room temperature. You can notice the propeller spins clockwise on icecream, and counter-clockwise on all the heat sources.

Funny, I was thinking about something like this yesterday but with a Stirling engine.

Obviously not practical in this state, but still a novel idea.

But it should be more effective than the same heatsink with no fan at all, no? If miniaturized, it'd actually be really cool for something like the Raspberry Pi, since the fan would improve cooling without drawing energy away from the board (or needing an external power source). Of course, that depends on how much benefit the fan actually offers. You might scoff at it trying to cool a desktop CPU, but it may well be useful for relatively low-heat (compared to a desktop CPU) cooling.

[QUOTE=Mango;47885012]Is it stupid to ask how the icecream engine works?[/QUOTE] The energy comes from the temperature gradient, not heat.

this could be useful for chipsets on motherboard.

the other side of the peltier will be the opposite temperature so its just be cooling down the cool side of the peltier, no?

wtf was that cheesy dinner ooze cake

Man, that diner sidekick option is a true charm, can't wait to put a fork in it.

I'm still hoping that one day we have way to cool cpu's without wind anymore. Watercooling is nice but I heard too much horror stories so no thanks.

If you want a better way to cool CPUs than wind, water cooling is the future. There are also non-conductive fluids that can be used for water cooling (including distilled water).

It seems very impractical.

[QUOTE=BusterBluth;47902396]Unless your doing something very intensive and unusual I don't really see the need for water cooling. It seems very impractical.[/QUOTE] I didn't say it was something for normal use :v: Just that it's more effective than fan cooling.

[QUOTE=BusterBluth;47902396]Unless your doing something very intensive and unusual I don't really see the need for water cooling.

[editline]8th June 2015[/editline] I've been using one for 2 years and it's been great. I was able to overclock my previous CPU with it and with my new CPU it's been keeping it's operating temp at below 40C even under heavy load.

[QUOTE=Dr. Evilcop;47901835]There are also non-conductive fluids that can be used for water cooling (including distilled water).[/QUOTE] Which become contaminated and conductive as soon as they touch practically anything [editline]8th June 2015[/editline] [QUOTE=StrawberryClock;47904272]There's plenty of "ready-to-use" watercooling kits that don't require you to mess with the tubing or the liquid. [/QUOTE] Unless you use them for space-saving purposes, premade water cooling solutions are pretty much just gimmicks to be honest. There are cheaper "regular" coolers available that cool better than even the more expensive (premade) watercooling solutions, and you don't need to risk a leak potentially ruining the entire system (which has happened to many people in the past) If you want proper watercooling for enthusiast reasons, a custom loop is the only real option. It's also significantly safer most of the time unless you fuck it up yourself

Also, while it's not too much of a stretch to imagine a heavy-duty fan heatsink to be on-par or better than a watercooled heatsink at cooling down the CPU, it seems useful with my current loop that the heat is directly expelled outside instead of being expelled inside the case. From the admittedly limited information I gathered on watercooled heatsinks, I was time and again recommended a premade loop instead of going with a custom made because people warned me that the accident and leak rate with custom made loops was much higher. In any case, my current loop does good enough job that I'd never have though it being sub-par.

[/QUOTE] That is absolutely true, and also part of what I meant with "space-saving purposes", for tiny cases which can't afford any heat to build up, they're perfect. And if you move the system a lot watercooling has another advantage, seeing as a top of the line aircooler is generally very heavy, which in turn can cause a lot of mechanical stress to the motherboard I'm not saying your cooler is necessarily sub-par, it's just that they're generally kind of pointless and risky

But what makes the premade ones inferior is that they use aluminum rads with copper blocks. This causes corrosion. The glycol slows down the corrosion, but they really only have a lifespan of a few years. Also the rads are generally think with a very low fin density. They cool a lot worse than my radiators in my custom loop.
