Cooling ideas

[progbuddy]

I've had a few ideas for cooling:

1. Sound Cooling- I was thinking of this when I was screwing around in class. Would vibrating air transfer heat in a fast manner?

2. Passive Case Cooling- Having a block of metal connected to the case, then have the case connected to a heatsink...

3. Cable Cooling (for smaller PCs)- Have a solid block of copper, with copper cables extending to a radiator outside the case.

Comments?

hmm well you could use the case as a heatsink its self but youd need a big hunk of silver

This little article might help you if you decide to go with the "cable cooling" route:

Not heatpipes. Cables/wire. I'm gonna be a mad scientist today. :hurt: ITS ALIVE!!

The Nzxt Adamas is a case heatsink. ;)

Sound cooling? Talk about being innovative prog! Cool idea! I wonder if it would actually show any signs of improvement? hehe, just be sure you don't accidentally discover the "brown note" or create a giant dog whistle if you try to do this. :p

well wouldnt it be best to use low frequencies so it pushes more air atone time

yea, but it'll vibrate way more, you'll have to fix your sub really hard so it doesn't crash everything. And the sound will have to be loud... lol.

That kind of cooling would be perfect for portable jukebox PCs, if you have al integrated speakers and underclocked computer (less heat) it could be perfect, lol.

I'll post a pic of what I mean by sound cooling. Basically, it would take low frequencies from a subwoofer (vibration dampeners, of course, for the HDDs and opticals) and run them through an external heatsink. How about a combination of all three??? WHOO! :D

Have cables running to a metal part on the case that will transfer heat to a heatsink, then be dissipated by sound.

I have 8 woofers, two 180 watt subwoofers, and 2 tweeters for experimentation. Maybe a higher frequency would work? Probably something inaudible (20-22 KHz)? I'll experiment with this tomorrow.

Just tested two 15 watt PC speakers. They actually do cool the CPU efficiently. But I'm going into more testing w/ different frequencies. Under load the CPU is at 65 C with sound on, and reaching blazing temps without the sound. I think a higher wattage and a pressure clamp should do the trick.

EDIT: Placed pressure clamp on, and temps dropped another 5 C. Under load, the CPU is at 60 C with sound on, 65 off. I think I'm getting somewhere. I think an ultrasonic noise would work well. I'm gonna try 17 and 20 KHz to see if they work.

how are you guys getting speakers to do 18khs

[Nagoshi]

Tweekers should not move any air, when my sound system in my room is very loud there's only air coming from the mid channel, and not the tweaker. Only sound. lol

This may seem like the case, but this is not true in reality. Higher frequencies emitted by speakers make the intervals of wavelengths smaller, thus producing a higher pitched sound. I believe it would carry the heat at a faster rate, and provide silent cooling solutions.

hmm, not sure about it being faster there prog, i actually would have to say a subwoofers going at something like 20hz would be best, rather than pushing very little air really fast its pushing alot of air slowly, like a 120mm fan at 5000rpm vs a 40mm fan at 15000rpm (values estimated of course :)

the passive case cooling thing is legit, ive seen a media center pc with 4 inch long fins sticking out of the sides and all the components were connected to the fins. ill have to scour my popular science collection(NOT an nerd) for the name.

the sound cooling sounds like a bust, but if it worked that would be something to brag about
