An Interesting Passive Cooling Idea

jacko · 23rd April 2012, 04:58 PM

Just saw this on Engadget and I figured I'd post it here for anyone interested in an alternative cooling idea to cool your chips. It may look good on a new style chassis too if it can dissipate the heat effectively.

um..yea silly boy...processor coolers are a great idea...did you see the thread here where one of the guys actually used liquid cooling PC components to cool his class A? VERY WELL DONE...look for it.

I use fanless sinks in my PC as well.

Cheers

This would look interesting with a point to point build. Probably a budget killer though.

yea I agree...thought not budget killer, some sinks are pretty cheap.

Out of curiosity I searched ebay for this sink, the chrome version was $120 at the cheapest. I would need two because I have "symmetry issues"

WoW that gives me an idea!!

I once had this idea of using lots of cooper wire frayed out to form a heatsink.
I got the idea in an art class where we made tree sculptures out of copper wire.
That heat sink isn't very big but the use of copper wire greatly increases the surface area of the radiating area.

A very small and quiet fan pointing downwards to vent the sink might increase its dissipation potential. Plus it makes for a cleaner chassis with the little silent fan blowing off some dust (only if top mounted though).

How are you gonna mount the chip onto the heatsink? You can't drill a hole through those heatpipes

Those fanless coolers are actually designed to use the air flow through the case for cooling, rather than having a fan of its own.

So outside a pc case, efficiency drops dramatically.

To mount a LM3886 onto one of these u need a clamp which can be just two pieces of metal and two screws.

These will look cool if the actual amp is made of a cylindrical transparent Perspex tube with two of these protruding on either side and two toroids mounted axially in the middle in a dual monoblock configuration.
