Low flow high efficiency coolers?

[PercocetPenguin]

Hi guys,
I was wondering if anyone knew the specs on heatsinks for removing heat from a cpu, and what the i7 requires in that aspect??
I ask this because this quotes it being able to remove heat at a rate of 100W/cm2, which sounds pretty good considering the i7 has about 2.63cm2 on it and generates 150TDP.
Or are my numbers completely off?
I would just like to know if this is feasible for cooling an i7.

okey reading that post,

i am guessing your looking at the last one.

This product does not eat heat and magically destorys it.

The first picture and second picture show you what this thing does.

At best it looks like a TIM application that would go ontop of a sink.

What this would do is spread the heat off the cpu thoughout the entire tim and not just pass it to the sink.

So thats why the first picture is all green and the second one has a thermal red spot in the middle.

You still need a good sink to put on top of these guys, as i said, there is no magic or science that can destory heat.

Yep.

I'm sorry, I guess I didn't explain the bottom left picture at all.
This is a water block. If you read the description it dissipates 100W/cm2 of heat with a water flow of 750µL/s. The point of this is using MEMS technology to create ridiculously efficient water blocks.
I've worked in the MEMS lab working on this on a different project, I've seen this hooked up with water pumping through it.
I'm just wondering what is an approximate rate of cooling for traditional i7 heat sinks.

varies a lot processor to processor.

and under load and idle are different conditions.

so if it disapates 100W/cm2 at low rediculous flow, where does the heat go?

i dont think water is capable of picking up that much heat with that little flow.

actually... 750µL/s (1mg/1µL/) (4.2J/C*g) (60C) = 189W
So it does seem possible. With that little water flow, I wonder if it'd be possible to power the pump with the heat generated from the northbridge.
By that, I mean the concept northbridge cooler (by Asus? a few years ago) that had a fan that was powered by temperature differences as I recall.

Hmm interesting idea.
Self powered water cooling system.
Technically if you put a peltier between the cpu and the heat sink it could generate electricity, then make that power the pump that pumps this tiny bit of water through the cycle.
I wonder how feasible this is.
