Watercooling with no pump...........

[JaY_III]

I know we have had people here cool their cpu as a test setup like this before....

the setup was a jam jar filled with water and the metal cap on the cpu....
well to say the lest it didn't work... ok well not once the water got warm.

Now lets say you get a nice large metal heatsink, like that purple thing on the main page a few days ago and have a larger water source surrounding that heatsink? Only leaving the contact piece (to CPU) exposed)

if you don't mind a large water container coming out of your case that should work right? The question is how much water would you need...yes I know that depends on how hot... how many watts does the cpu put out etc., etc...

I think I may go about doing this as I have nothing better to do in my free time. So what does anyone think?

The advantage to this over a jam jar would be(well my plans)
1)heatsink still has contact with CPU
2)more water
3)not a closed water system so HOT water still will evaporate (just have to top it up)

there's no way you can have your cpu cooling with water without a water pump circulating the water. It will just burn the CPU.

Well I kicked the plug on my aquastealth and shut down the pump without knowing it. Its only a celeron 366@550 but it ran fine for 2 hrs before I noticed it.
Sure as hell would not want to do that on a hot cpu.
I always wondered if the water was circulated by convection or something like that.

Actually they make laptop heatsinks that are pretty much watercoolers with no pumps. It looks like a small pipe and can be bent into any needed position. When the liquid next to the heatsink is heated it travels up through the center of the pipe. When it reaches the end it cools and travels around the outside of the inner, cooling more as it goes until it reaches the CPU again and repeats the process. Neat idea... wish I thought of it.

Actually you can cool a CPU by water convection. Place a big radiator at the top of your case, a resivior at the bottom and the CPU in the middle - with a return hose to the resivior of course and viola, convection cooling.

Now, take this with a grain of salt AND DO NOT DO THIS AT HOME. In theory it should work, in reality there are a number of problems.

The only guy who I have seen try this and succeed was at www.benchtest.com. He set a convetion system up and had a fair amount of success. Enough to keep the CPU core from melting at least. This was on an older PII which did not have the wattage requirements of the PIII or AMD chips - so it will probably not work with a current processor.

you should check out his site though. If everybody followed his testing throughness then there would be a lot less BS on the web about cooling....

that last idea seam like it could still work....
i dont hav ea supper hot chip to start with only a Celeron 633..... FSB is @ 105 though.......
But its not like the K7 or anything.

I'll check that page out... and based on what i read i may give it a try still.... like i said, need something to do in my spare time.

I still dont see why some people say it will not work, still got that heatsink that shoudl be able to take care of the heat (for a bit anyways), then all the water to soak the heat up with a large enough supply of water ... it shoudl work fine.... have a rig setup something simular to the one listed abouve my post and the one in the laptop....

well, i dont know, they are just ideas

I really suggest that you go have a look at the benchtest site...... Consider yourself warned....
