CPU Convective Water Cooling
biso writes "The possibility of cooling a CPU with gravitational convective flow of water is here analyzed and experimented with positive results.
Many liquid cooling systems have been experimented by overclockers to better dissipate the heat from CPUs. The major part of these coolers is characterized by a relatively complex system requiring pumps or other active devices. Sometimes even liquid nitrogen is used. I built a simpler cooler, able to dissipate the same heat flux of a normal heatsink."
Trasformer oil is insulating and would not short-out anything. It could also cool the powersupply at the same time, without the inherint saftey risk water subjects us to.
...powered by water (or even antifreeze) could conceivably do two jobs: provide cooling for the cpu and produce power. It wouldn't have to be all that big either. It might not produce that much power, but probably enough to light a small desk lamp.
So far left, I'm right.
It's kind of ironic istn't it that CMOS PCs will eventually need the same plumbing as the TCMs they were supposed to replace.
Hey I had a 9021-721 MVS/ESA mainframe that used TCM's cooled by a 400psi cooling system. The great thing about the next gen CMOS mainframes was that even though one TCM was now replaced with 3-6 CMOS units, we didn't need a massive chiller system.
Oh well, guess everything will have huge ass chiller pumps now.
While I admire all of those who are willing to actually pipe water into their computers for the sake of keeping them cool, I am still more than a little frightened of this idea. Knowing me, something would end up leaking (probably through fault of my own) and my precious tower would go up in a ball of flame or some such. Rather, I choose to take your regular old air cooling and make it more effective. Through proper cable management, good airflow paths, a set of nice quiet fans, and the ability to control them with respect to how much they are needed, I keep my fan almost as cool as a friend of mine who does have a liquid cooling system, and with very comparable noise levels. If you're willing to do some work and set up a decent air-based system (and be willing to clean out the dust), there's no need to balance a bucket of water precariously on top of one's computer... : |
I know I have. I think eventually we'll see some commercially available sealed systems that use some liquid (probably not water because of its corrosive properties) and convection to move it around.
Something idiot proof and self contained with no mechanical parts, save perhaps a slower turning large fan to exhaust air.
So far existing heat pipes are not much more than a novelty. The wick style ones with alcohol as a fluid (mentioned here awhile back) look promising.
The giant skivved aluminum/copper blocks with the big ass fans aren't going to cut it, not just because of noise, but practicality.
I don't need no instructions to know how to rock!!!!

Without the need to implement that bulky bowl of water.
Yes that would be interesting. Infact, it might work even better especially if his water column was better designed with the larger processor. Larger processor = more heat = less dense water = faster rising water = more water moving to replace the warmer water. But I have nothing to back this up. But hey, Ford was able to cool the Model T with passive water cooling, so it could work. Key word is could. Don't quote me on it. Side Note - Nuclear subs now use convection cooling to end even the *quite* pump noise.
Reserved Word.
...the motherboard manufacturers just don't put the processors on the back side of the motherboards.
Think about it. If the processor and other heat generating chips were on the reverse side you could mount the motherboard in such a way as to press against the large metal backside of your case cabinet. The case cabinet could be designed in such a way as to have indentations that force the processor flat against the case with heat sink gel. In fact the entire case back could be a water-cooled heat sink. This would keep the inside of the case "water-free".
Sure, this would take a radical new case design and motherboard (another industry standard), but that seems to be where we are headed right? I mean processors are getting hotter and Intel and AMD are trying to figure out what to do.
Why not?
BTW, I think it has something to do with the fact that the motherboard components are all wave soldered on one side. This would melt most plastic components on that side. I'm not sure about this.
That was a very informative post, does anyone know if motor oil is conductive, I would think that a quart of 5W20 or another light oil would flow pretty well through a small submersable pump. My favorite transformer oil story was from a local Utility guy who came to our school years ago. He asked us if we ever wanted to shoot the transformers with our pellet guns, and then told us that he used to want to as a kid, but that it would be a bad idea since the oil would leak and the transformer would fail possibly explosivly.
What I found funny was that I don't think a single person had ever thought about shooting a transformer until he mentioned it, and the fact that they could explode might be something that would encourage young boys to shoot one with their pellet gun.
Degaussing scares the bad magnetism out of the monitor and fills it with good karma.
I guess Intel meant the surface of the Sun. This outer layer (photosphere) has a temperature of 6000C aprox. Yeah, it's damn hot but quite below from the 15000000C of the core (where the nuclear reactions take place).
:-)
Molten lava temperature is ~1000C so only 5000C to go
I remember posting in a car forum after doing some research. Oils are very BAD.
.6W/mK (bout halfway down the page) .13W/mK.
Thermal contuctivity for water is
The oil I found was from some company called Slovnaft out of Slovakia (the only one I could find that would provide details). But their oil that is specifically meant for moving heat has a thermal conductivity of
Another thing I might point out is if youve ever got motor oil on your hands youll notice it feels warmer than water of the same temperature. It doesnt carry heat away like water will.
