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."

<offtopic>That reminds me -- a few years ago, I went out of town for a few days, and when I got back my old P200 refused to boot. I yanked out cables and cards in an attempt to get the old beast up and going again, and when I yanked out the sound card, it booted. Well, I put everything back together, and then looked closer at the sound card.

It had a nice, dried puddle of mouse piss on it, so I put it aside and waited for the next opportunity to grab another one.

I thought (after I'd gotten another one) that I should have called Dell tech support and discussed the problem with them:

(them) "Hello, <speil>"

(me) "Yeah, I've got a mouse problem."

(them) "What seems to be the problem?"

(me) "Oh, it sort of pissed on my sound card."

odd

ok, i can see the extra bit of silence from not having a pump would be nice. but ... isnt a bowl of water on top of your computer just asking for trouble? something tells me this guy doesnt have cats.

not that complex...

[AmigaAvenger]

I've built numerous different water cooled systems, and the $20 pump from the aquarium supply place is NOT the most complex piece. A good waterjacket for the cpu is by far the most complex and generally most expensive single piece, and also the one that is most critical for good performance. Still need the waterjacket in this design, so it isn't really saving anything...

too hot

I really think that phase change cooling systems are the future of the PC. Only with phase change cooling systems do you get high quality cooling able to remove the utmost heat away from a CPU and cool it to below freezing.

I saw a presentation by Intel last year in which it pointed out that modern CPU's emit more heat per area than molten lava, and they expect that within a few years they will emit more heat per area than the sun.

With these considerations passive water cooling is only a good first step and bound to be insufficient, even over the short term.

Allow me to suggest...

...using sponges as sound dampening material inside the case. Who knows, it just might save your computer when somebody bumps the frickin' table and dumps that bowl full of water over everything!!

Simpler, Cheaper Method...

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... : |

that picture of a bowel of water on top of an open pc tower case is not something I would necessarily run....

Bowels of water on his PC, this is something I definitely DON'T want to see!
