You're going to learn alot more about water cooling systems before all is said and done. I recomend a 50% glycol solution in your water to control algecide and help with the thermal transfer. That... and NEVER use deionized water in a metal closed loop system. It will ionize somehow.

Well mine was a daredevil project which aimed for 100% passive cooling. I modified an old oil filled electric radiator (household heater) to act as my water reservoir and cooler. Despite the glycole in the water after some time the water begun to be completely saturated by copper. When we moved house to house and I had to drain the system, it never came back on.

I've been itching to get a decent radiator and a new waterblock thoug..

I guess I never learn.

Glycol only inhibits the algae growth. You were dealing with Osmosis. Read up on hot water heaters and the zink strip to see how to fix that.

It had a good life LePaul. If thats the card I think it is it had 2 years of hard gaming in a previous life.

S!

Actually Glycol is an anti corrosive also, that's why car coolant should never be without it. But as it seems either I didn't have enough of it or then the electro-chemical reaction was just too strong to be blocked.

I'm curious how much people actually gain from water/liquid cooling? Some of the systems I've seen are pricey, do you really gain some phenomenal cooling?

I imagine if you are big into overclocking things, it might be neat....but I'd be interested to know how a regular system temp compares to liquid.

For regular clock speeds water cooling is all about noise reduction. Passive fanless, and noiseless systems like the Zalman Reserator (or something like that).

I think you're confusing anti-buildup with anti-corrosive. It might have some protective properties, but the water properties is what drives the corrosion, especially with copper. It's simply a matter of ion transfer. If the water sees the metal, it will react with it in an attempt to equalize charge. The only real way to counter it is to completey insulate the metal (glycol is not an insulator) or make the water less likely to grab ions.

Once again, look up "zinc strip" in regards to water heaters.

LePaul, I may still have a used video card laying around at my shop. If you want to use it until you can get something else, you are welcome to it. Better than nothing I think.

LePaul · « **Reply #23 on:** January 08, 2007, 06:44:01 PM »

Shoot me a PM...I have other video cards, just not 3D able.

Wasnt ATI bought out recently?

10-20 C drop in cpu temp or more , case temp drops . no more big heavy cpu heatpipe or hs fan pulling down on the mainboard .

The bigwater 745 is 149.00 . the Bigwater se is 99.00 at frys
http://shop4.outpost.com/search?cat=-51744&pType=pDisplay

Add a VGA cooling block and your still under 150-200 . All you need then is to keep just enough airflow to cool the hard drives and the ram..

A full blown Danger den set up get up about 250-300 ...and doesnt really have any adv over the TT745.

Yes they're part of AMD now.

Standard coolant glycol that I used contains anti-corrosive chemicals:

I bought this one last year for my old puter:

Thermaltake Symphony:

Modded it with a more powerful pump and a fan controller on the cooling tower. I'll be using this as the primary heat exchanger on my new system as well. Makes my puter look like a friggin mini-nuclear reactor.

I started experimenting with watercooling mainly because I wanted an ultrasilent rig. Turns out that most pumps make an audible hum that bothered me so I didnt achieve what I wanted despite building a totally passive radiator.

Currently I'm planning on building a box in the cold cellar of my house and use it through extensions from another room.
