Water cooling beyond.

http://www.techspot.com/news/30348-ibm-demos-internal-cpu-water-cooling.html
Sounds like this might be a way to implement it in laptops too in the future...

 

this=heavy OC-ing in laptops

 

Pretty much what I was hoping for. Pipes the size of humar hair, woof.

 

but would it be as effective as in desktops?

 

Why not design it to use something like R410a?

 

Okay guys, think of it, how much water can fit into those micro channels, the amswer is barely any. I dont see how this could do anything to benefit the processor. It will only cause more problems, cause a leak could be deadly for the system. This has been implemented by IBM and SUN in the past, and to no avail, it did nothing, so dont get your hopes up. IBm is at it again, but I dont think the results will be any different than their last attempt. Water cooling cannot do more than air cooling. All you need is a big heatsink and a good fan.

They probably do not use refrigerants, cause the refrigerants will only work well when their is a huge difference in temperature gradients. And you would need a more powerful pump to move refrigerants than water. Also refrigerants are "hazardous" materials, so they probably will not be used in computer chips.

@K-TRON
This would actually be a huge improvement over both air cooling and current water cooling, because the water is actually in right next to the silicon.

But right now, the best, and by far coolest, way to cool your desktop is to put all the parts in an aquarium and fill it with mineral oil.

 

Only if you have a way to chill the oil

 

Phase Change tops the list but it starts at 400$ used.

 

If you modify a window A/C, you can get phase change for under $100.

 

Well, you guys are quick to dismiss it. But if you look at the pics, it actually might help more than just heat.
I for one say it's doable in the future...

 

I agree, in the future it could make a big difference. Not now, but later on it could. It did say 5-10 years which is plently of time to improve something like this.

 

I thought this was an internal heatpiping system. It is improving on the standard thermal heatsink, or whatever it is called. Water cooling in a laptop doesn't make all the much sense. It would only make the laptop heavier.

 

Talk about energy efficient computer cooling

 

If I lived near someplace where it snowed all the time, I'd just run a water cooling line outside and cool my PC that way.

 

Well, exotic cooling is fine. Me, myself and I hope for future high end GPUs and CPU with TDP of 1 to 5 watts. If not, your next killer laptop may have huge fins sitting in a vat of Fluorinert?

 

will never become mainstream or practical beacuse of 2 factors..

1 the laptop would be very heavy
2 radiator .. u may be able to shrink the pipes get it close to heat sources however that is really just water bock developments does not change the fact u will need a way to dissipate that heat from the liquid... and in a laptop environment a radiator is just not going to work unless laptops shrink by half there current size. heat pipes + fans are still the most efficient..

I remember on gametrailers last year i watched a vid of a new fan like technology that they would use in mobile phones it was basically as thin as a credit card but blew alot of air via some sort of static electric reaction.. that would have big applications in the laptop space in the future..

but atm we have midrange desktop Gpu cores running in laptops like the 8800mGTX so really heat is not whats stopping them.. its a market for it/batterylife.

and most gamers like the dark of a den ^_^ and are not very mobile

u know i was going to build my desktop into a metal case last year monitor and all so i could lug it around with me... i gave up after i failed to find any UPS that provided decent battery life at a good price/size 1hour for a 500wat is like 1000usd !!.... ive seen afue sistems like this watercooled but yer just mobile desktops really...

im ranting sorry

 

Water cooling is just a hint at the future. A liquid heat transfer system may be more efficient at transfering heat to an exhaust fan than a long piece of copper.

I would beg to differ here. While batterylife is a concern overall, it is no longer a top priority.

The laptop market is starting to evolve incredibly fast. Portability is no longer as high of a priority as it use to be. Now acceptable portability on 15.4" can be "as long as I can lug it from my desk to my couch." With the large price drops and increased efficiency in smaller laptops (13.3" and below), they become the new portables, which the 15.4" becoming the new desktops. At 15.4", heat and performance will become a bigger factor than portability.

 

Toshiba was gonna release a water cooling laptop in 2005, but somehow they cancelled the project.

 

Thermal loops are probably superior to water cooling both in terms of delta T and efficiency. The amount of heat needed to evaporate refrigerant is very high. And since gas is less dense than liquid, the refrigerant can effectively pump itself.
