Natural Circulation

[ZombieJesus]

-Natural Circulation-

Water moves naturally due to density changes from heat.

To build a pumpless system all you need is:

1) A low flow resistance waterblock.

2) Large diameter tubing for less flow resistance.

3) A Radiator with low flow resistance.

In order for natural circulation to occur the radiator at all times must be positioned above the waterblock(s). Any reservoir should also be above the waterblocks. Reservoirs should also be above the waterblocks.

The lower the flow resistance the better the cooling performace. Use a passive radiator to make the system fanless. Imagine a totally silent, super reliable watercooling solution.

sorry to burst your bubble, but thats woefully ineffective.

You have tried this?

ZombieJesus,
Don't let them get you down...
I like seeing my username in posts also.

How about you build it up, take pictures, and post test results on that type of rig?? Put NORMAL components in it, not some underpowered hardware, so it can be tested in real world settings...

As far as predicting if it will actually work or not, I don't think you'll see any decent temps that way. Best case you won't get any better than a low noise air cooling setup. Worst case, your system will shutdown soon after boot, upon reaching the thermal 'kill zone' for the mobo and processor.

IF such a system worked, or worked even close to well enough, then products that used heat exhangers for cooling would also use it. Vehicles (cars, trucks, etc.) have water pumps to move the antifreeze inside the system so that the engine doesn't sieze (which it will if you run without the pump). The only way to do what you're thinking is with heatpipes, such as the ~$1000 Zalman case... That would make for a silent system (except for drive access sounds) but it's a bit beyond most of us.
