What are these bongs you speak of??

[Creepin_D]

Can any one give me a step by step on how ot make one?? And why are they so much better than "normal" water cooling??

Here is a great article here
You use a piece of PVC and a shower head, pump the water to the shower head-after the cpu(and also with the restrictor removed) and let it "rain" inside the PVC-about 2/3rds of the way down-install a tee, or better a y and installed a fan in it-blowing into the y-so the air flows into the water as it falls down the tube-and you can cool the water below ambient temps. Read the article, and note it is 5 pages long.

Thats cool! no pun intended..

Has anyone tryed using larger sizes of pipeing?

Yeah but 4" fittings are cheap and work just fine. 6" and 8" get expensive. Combining a bucket cooler with a bong cooler gets the results that a larger pipe size would without the expense.

Cool, I ask cause the town I live in is redoing all its underground gas lines so there is a ton for PVC type piping laying around...and this stuff is hugh 8" atleast...and they have the "y" pieces as well....

...or you can just get a length of hose, coil it up, and slit or punch holes in it. It's perform just as well as a shower head and you can potentially punch hundreds of holes into a short length of a hose. just glue that coil of hose where you what it to be or in place of the showerhead.

BTW, 'bong'-styled water cooling can potentially perform just as good or better than a water cooling system with a radiator. This is because:

1. Surface area of water is increased hundredth-fold after leaving the showerhead or some spray mechanism.
2. The water droplets are moving. This means, in another way, air is moving relative to the water droplets. So, you don't really need a larger fan- just spray the water faster and more voluminously. Fans are only needed to blow away the humid air inside the bong and not at the droplets.
3. points 1&2 above is just about the heat rejected by convective means... water evaporating will take alot of latent heat away with it. It'll be just a few percent of the water flow but that's alot of heat removed!
4. Economics: No radiator to buy.

Unfortunately, depending on the beholder (and the builder), home-made bongs can be an eyesore (ie. don't look that cool compared to commercially-sold sets).
