Here's some of my idea. To increase the efficiency of contact between heatpipes and fins, if we could cast the copper pipe and fins together or we form the fins of the heat pipe using superplastic forming. To increase the efficiency of the heatpipes we could make it hollow and fill it with nano metals suspended in cooling fluid. And instead of relying on convection or pumps to circulate the fluid we use magnetic force to drive the metal particles within the fluid. For example, let the heatpipes be round as in the picture, and the fan is at the center. Put small magnets at the tip of the fan and while the fan rotates it will drive the metal particles and the fluid inside will circulate around the circular heatpipes. To increase the effiecency of the cooling fluid we could explore the possibilities of using liquid metal like mercury as the ultimate cooling fluid (great conductivity + convection effect). To increase the efficiency of the fins, we should design the fins so that the surface area of the fins increase approaching their tips. This could be done by gradually thinning the fins as it approach the edge or making honeycomb holes near the edges to increase the surface area. This design is inspired by nature (tree trunks divided into smaller branches and divided into smaller twigs) this gradual increment will increase the efficiency of the heat flow inside the fin and also heat transfer from the fin to the air. I will post some more after I get new ideas. Cheers~

Simply license the Dyson Air Multiplier technology and miniaturize it. Removing the fan from the system would be an enormous move forward in heat sink design.
1. team up with a case manfacture and make a case that will blow cold air directly on the cpu cooler and has a hose with a fan that will pull the hot air outside

Start with a "universal base" or set that can provide clamping to all currently popular motherboard sockets. The hardest part of heatsinks is attaching it to the system board. Create the base and a method for attaching the sink itself to the base (rotating cam like the AMD sinks would be easy to create the pressure needed to put the sink on the base) A picture of the idea is here: http://www.sublifer.com/hsfidea.png

This is my entry for: heatsink design utilizing fans
Well I would have to say in designing a heat sink, let's stick to what works already. The Hyper 212 plus works really well and is cheap, so lets borrow from its design.
* We would use the block of fins with 120mm fans attatched to both sides.
* We would also keep the direct contact heat pipes.
* The direct contact heat pipes would start at the base and run through the fin block to distribute the heat
* A set of tubes made of a material that doesn't pull much heat, plastic would probably work well, would come down through the fin block to the base and connect to the direct contact heat pipes
* This would create a tunnel in which we will run air through to help move the heat
* There would be a 40mm exhaust fan that pulls the air through the heat pipes on top of the fin block
* There would be a 40mm intake fan that would force air through the intake pipes that eventually merge into the heat pipes that sits next to the exhaust fan ontop of the fin block
* The pipes would come out of the top of the fin block and converge into a small funnel that the fan would fit into
I believe creating a small wind tunnel inside of the heat pipes would help move heat away to the fins to be distributed faster.
Also the intake pipes would not have to pass through the fin block and could be arranged outside of it if needed.
Please click on the link to view a diagram I mocked up to better illustrate my description.

I think a heat sink/blower combo would be very interesting. Blowers do not have the "blind spot" that fans have. I remember that Cooler Master's JET4 cpu cooler was a good cooler in its days, but suffered from high noise levels. I would like to see a heat sink (tower type, with heat pipes, it doesn't necessarily have to be a top-down configuration) with a blower mounted on it. The intake of a blower should have a bevel that you can use to attach a tube/duct so it can draw cool air directly from outside the case. The exhaust air could be directed towards the back of the case. I think that mounting the blower so it sends the air stream upwards, towards the top of the case (where you have the PSU of another fan) would not be possible because it would most likely collide with the northbidrge heatsink and/or the VGA card.
The whole idea is to improve the uniformity of airflow through the fins of the heat sink while also providing a separate airflow path for the CPU cooler.
Here's a drawing: www.mapa.go.ro/heatsink_blower.bmp
In my point of view, blowers could also be used to create single slot GPU coolers, with a blower type (tube shaped blower) fan at the end of the VGA card.
Also, a long, slim blower (1 cm diameter) would be nice to have. I would use it to push cool air underneath the motherboard. Also a case that would have a long, rectangular mesh to provide and exit point for the air underneath the mobo would be nice. A lot of manufacturers use the bottom layer to create big copper areas that act like heat sinks. Providing airflow to this side could lead to better VRM termperatures, thus improved stability and life time.
Another ideea: direct touch coolers. I would try to get rid of the aluminum fins between the individual heat pipes. I would try to create heat pipes that have a rectangular cross section in the area where they have to form the heat sink base. The heat pipes could be soldered together using a process similar to re-flow soldering. A U shaped piece of aluminum could be used to wrap the sides and the top side of the heat pipes to provide strength and a suitable point for attaching the retention mechanism. Using rectangular shaped heat pipes would allow to create an improved active surface. Also, if it would be possible to engineer the heat pipes so the side that is in contact with the CPU is twice as thick as the other walls. This would allow better finishing of the heat sink base.
Here's what I mean: http://www.mapa.go.ro/rectangular_heatpipe.bmp
Water cooling: It would be interesting to add peltier elements in the water tank for example. They would be used to lower the temperature of the water below the room temperature. Of course, the peltiers have horrid efficiency and generate a lot of heat on the hot side, but the purpose is to limit the temperature of the cooling fluid to a point above the temperature that could create condensation on the tubes and metal parts (water block for CPU, GPU, etc).
I would also like to see some kind of distribution system: a thick tube, ~20cm long with output ports for coolant distribution for every water block. A similar part would be used to collect the incoming war coolant. Also increasing the water quantity helps because of the natural thermal inertia of water.
To sum it up: i think blower could offer some interesting design possibilities. I like the most the fact that they produce a 90 degrees "bend" in the air flow. They could be used for CPU, GPU and backside of mobos coolers.

Conventional: Low-profile impingement with 140mm silent fan for adjacent board cooling, 8mm heat pipes (as many as will fit), bottom half to two-thirds of fins array copper, top half to third of fins array aluminum, heavily finned aluminum base over copper, all fin edges/fan blade faces heavily irregular to facilitate air flow. I'd experiment with thin fins and/or wider spacing -- often improve performance. Better: Same fan, vapor chamber -- we've seen what this has done for Sapphire's Vapor-X line! Best: Same fan, oscillating/pulsating heat pipe: (scroll down to pp.7-8).

Zalman, make 4-pin PWM fans standard in your next high performance coolers! This is a really simple suggestion, best of all it's extremely easy to implement. You'd think it would be a given now days, but it's not. The CNPS10X Quiet is an unfortunate example of this. It would be a much better option in my opinion if it had a PWM fan instead of the 3-pin fan that's currently used.
What about a water cooling system with a 2x 5.25" slot radiator/pump/reservoir?
Comes pre-assembled, just put it in the slot, secure it, lock the CPU block (all copper) in place (pre-coated with high quality paste), connect power and boot it.
Throw in a few RGB LEDs to color the transparent water reservoir and a USB interface (motherboard connector or supplied type A adapter) with software (and Linux library) to set the color according to what mode the CPU/GPU is in (e.g. aqua blue when GPU is in 2D mode and CPU idle). Make them flash in a certain color pattern depending on weather the CPU or GPU has reached the temperature threshold. Of course you can turn off the LEDs but it will still flash at the temperature threshold.
Most importantly, it pushes the air out of the case through the radiator by default (reversable if necessary). This way it will increase the airflow inside the case over the other components while maintaining a thermal barrier between the inside of the case and the heatsink.
The component layout inside the unit itself (seen from the front) would be radiator in the middle with an 80mm fan behind it, reservoir to the right and the pump located inside the reservoir at the back.
Basic model comes without LEDs and with a single square radiator.
Deluxe model comes with LEDs and dual square radiators.
Lastly, this might me a bit over the top, but maybe build a special case which has air intakes on the sides right behind where the fan will end up, so that the air flowing through the radiator would blend with the slightly cooler room temperature air for better efficiency.
Sorry for the lengthy post, hope you like the idea

if you havce the copper heat pipe make a direct contact with the cpu then havce a heat sink on top with and a fan to absorb cool air and kick the warm air upward cuz heat will rise, then if you add a mini water pipe through the back of the copper plate to cool that, it would be awesome
I would look into dimpling the heatsink fins to improve airflow and cooling.
I'd make more use of squirrel cage fans instead of the regular fans.
I'd look into using variable pitch fans.
I'd look into using heatsinks on both sides of the motherboard.
I'd use the case itself as part of the heatsink.

I have a theoretical design in mind. Its like this:
Sticking to the standard round zalman designs, the heat pipes (made of copper) spiral around the heatsink. An internal fan is to be placed in the middle of the tower cooling so that it can suck the air out. i know its not the conventional design of blowing air on the cpu but my concept is to create a vortex and blast the air outwards. if such a setup is mounted in a manner in which the top end of the cooler faces the left of the case, a side fan can be used to move the air outwards. considering that most people keep their pc's at a max height of 4-5 ft, it is advisable to use the top mounted fans as intake as cold air settles in the bottom in a room where as the same doesn't apply to a pc case as the delta in the temperature/area is very less.
in case you want pictural designs please let me know. i am just happy to help

1) Practical cooling system must transfer heat from components to air
with smallest possible temperature difference (component - air temp).
2) It should also be as quiet as possible.
To keep temperature difference low, lot of air is needed. (1 liter of
water transfers as much heat as 4 cubic meters of air.)
To keep system silent, air must move slowly.
So radiator which transfers heat to air must be very large. Solids do
not really conduct heat very well. So heat pipes or water is needed
to transfer heat from components to large radiator. Large radiator
should be easy to move, so that components can be changed. I have not
seen flexible heat pipes, so water cooling is only possibility.
A PC-case should have side panel replaced with radiator. Gaps
between radiator fins small enough, perhaps 1 mm, so that radiator can
replace case wall. That also maximizes surface area. Case should have
slowly rotating fans everywhere possible. Those fans would push air
into case and then out trough radiator.

First of all wanna start the idea of direct heatpipe technology. Lets begin having a 6-8 heatpipes of full copper materials. lets say same with the model CNPS8000A. But not only just that. lets make this a hybrid. how bout at the installing a direct heatpipe and a water block together? heatpipes connected to the waterblock. have some fins and an ultra quiet 120mm fans that connect direclty to Cpu and will be automatically controlled its pwm by the mobo. and back to the waterblock the coolant will run through a 120x240 radiator with copper fins and is being cooled by 2 x 120mm ultra quiet fans that can be connected on top, at the back or at the 3.5bays in most modern cases today. thats my idea of a hybrid cooler. AIR+WATER COOLED!
