[citation][nom]pjmelect[/nom]I have often thought that it would be a good idea if the copper area that makes contact with the CPU was gold plated. It wouldn't add much to the cost of the heatsink yet it would dramatically improve heat conduction to the heatsink from the CPU.[/citation]

I'm not really understanding this one... :S
Do you actually mean silver? Or are you referring to the fact that gold tarnishes less easily than both copper and silver?
 
use a peltier to cool the CPU and use water cooling to cool the hot side of the peltier.

or use a peltier to cool the liquid in a water cooling system.
 
I would like to see GPU cooling solutions that utitlize low and wide crossflow fan types. With SLI and Crossfire configurations pretty much stacking cards on top of an axial fan design for cooling it seems to me that there can be much more efficient method of drawing air through the sinks. With the impeller set to draw in air from the rear or possibly the side of the card and a plastic cover similar to a lot of the stock cooling configurations it can easily be channeled out the rear of the case. Easy in, easy out. Sounds good to me!
 
Bag of Ice. Perfect heatsink. Melts and becomes water. Replaceable. Win.

Through out the 70s and into the late 90s cpus were often manufactured with HFG gold electroplated IHS.
 
A system where heat energy can be transferred only in one direction, and this goes to a surface which can be pulled out of a 5.25 inch bay, and then be used as a hot cup holder to keep my coffee warm in the morning, and heat up my cheeseburger with bacon for lunch.

Ya noctua is good but do they make heat syncs? I've used some noctua fans in servers and they work great and are a lot quieter than what they replaced. But the 120mm sitting here isn't keeping the drives in this tower cool. But at least the drives lasted long enough. If you get more than 3 years out of a hard drive that is constantly spinning, it is enough.
 
Liquid Cooling Idea:
I'd like to see 4-6 hollow copper cooling tubes at the contact plate. These hollow copper tubes would then be filled with a liquid cooling solution and attached to the radiator to be circulated.

The extended surface area of the tubes would help with removing additional heat. Additional surface area could be acheived by spiraling these tubes around in a tornado(spiral) shape to keep it from getting too tall. The spiral would get bigger as it progresses away from the cpu contact place.

The radiator would constantly flow the liquid through to ensure proper circulation of the warmed liquids.

Depending on the size of the tubes we wanted to go with, we could have the radiator mounted at the CPU with the ouput of the hot air through the side case fan.

This would be ideal for cases with a clear side that have additional cooling fans whilst still allowing for additional case fans to flow excess air on the chassis.
 
I would love a heatsink designed to looked like a city, with fins shaped like staggered skyscrapers. It would look awesome on a motherboard, and I suppose it would have to be fanless.
 
CPU block that is split with tightening screws pulling both halves down onto the heat pipes. Angled heat pipes which adjust so you can position to the radiator block, which you cut a hole in the back of the case near the exhaust case fan spot, put the block outside the case, and the fan inside. Let people mod the case, or make a list of approved ones where the grill on the inside is cut out so you get better airflow.

I did a simplistic diagram of all but the heatpipes going onto the CPU block: http://screencast.com/t/ZjVhNGM2N
 
I'm thinking rather than solid fins on the heat sink, allow the fluid from the heatpipes to flow through them as well. Kind of like the radiator on your car. This would be rather expensive for the end user but something to look at I think.
 
Well I do have some rather unique ideas with a few that are meant for hard drives. As for cpu cooling quality isn't going to be cheap such as all copper construction with HFG gold electroplate (14k) and thick walled heatpipes. Direct touch only works due to most coolers that employ the standard heatpipe designs do not have proper contact with the heatpipes and the base as well the fins are dreadful. I also prefer very heavy coolers that have proper mounting. If it can wiggle or slide it isn't secure. My chipset coolers are bolted in place rather than cheap plastic push pins. My drives are firmly mounted with great excess of screws used. Hell I used 18 screws on my top drive. 4 to mount the drive into the 5.25 bay adapter. 6 on each side with one that mounts a bracket that acts as a heatsink while mounting a 80mm fan that exhaust out the top. 8 more to mount into the case. Then 2 more to mount the fan. :)

As for coolers that block access to the ram well I got that solved with a handy mod that keeps my ram nice and cool which allows me to use lower volts while being good enough for 24h use.

Total # fans /9
Case open /yes
Lowest recorded temp /22c /device top drive (ide)

As for my intel rig I removed the IHS and replaced the gray crap that they used. e7200 3.6ghz
 
Most great heat sinks are make out of copper, because it conducts heat better than aluminum and similar materials. But ever since I heard that silver is the best heat conductor, I always wondered why nobody had ever made a heat sink out of it. I know it's a precious metal, and much more expensive than even copper, but if you're going to make the best heat sink, you should use the best materials.
 
For a liquid-cooled system, I'd start with the chip and have the whole die immersed inside a non-electrically conductive fluid passed through a small CFC refridgerator.

But then I guess this comp is for commercially viable designs....

+1 for remembering silver is the best conductor.
 
I am designing a CPU to work at 50 Yotta Hertz, which requires no cooling, and will emit a rainbow inside the case, will put many cooling companies out of business sorry Zalman..

Most people already complain about how they don't want to spend more than $60 for a heat sink fan. Not to mention that convection cooling only goes so far until you need to start looking at phase. Basically, diminishing returns.

Take a look at commodity trading and you will also notice that copper is sold by the pound, and silver is sold by the ounce. If a pure copper heat sink is $60, you can expect the pure silver heat sink to be around $5,300 based purely on commodity values. Consider also that the price of that copper was not considering any scrap rates.
