Liquid Cooling Temps!

My athlon system w/ outdoor radiator averaged about 15-20C when idle and under load. That is the temp it is outside most of the time where I live so it couldn't really get colder than that. And the volume of water/size of radiator in my system kept it at that temp so well it didn't change even when running prime95 or other stress software. I even got the same temps on my northbridge when idle, it went up a degree C or two when under load though.

My current P4 machine w/ fully internal liquid cooling idles at around 25-30C depending on how warm my room is. If I leave my window open at night it gets VERY cold and sometimes drops to around 20C. I usually top out at around 30-40C under load. That is also dependant on how hot/cold my room is. Again, My cooling systems have so much water in them and have such large radiators they usually stay fairly close to the current environmental conditions. The chipset in this machine gets about 5C warmer than my CPU when idle and under load logically due to it being a series system so it gets all the warm water off the CPU.

You can see pics of my setups if you go to my sig's link.

Air can and will have an effect on your temps. I have put in many hours on 3 different cooling projects lately. One of the cooling systems that I built has an aquarium pump that has an adjustable water flow and air flow. This means that you can adjust it so that it has no air bubbles to as many as you want. Using different flow rates and different air adjustments there is no doubt that air bubbles to any degree have a negative effect. Something to consider is increasing your resivior and buying a pump from a pet shop. You can get one for $20.00 - $40.00 dollars and the cheapest will be alot better than most of the ones that come with these cooling systems. I also bought a water purifier/cooler that holds up to 4 gallons of water. Its intended of course to be used for home water consumption, but at $59.00 you cant beat that price for a combined resivor and built in water chilling system. I have gotten my system as low as 10C under load. Over a 24 hour period, it doesnt get warmer than 22C. THis is cooling an Intel 3.4 775 CPU.

I don't have a clue, although hot air rises and perhaps it was getting caught in the rez instead of cirulating in the loop?

Anyay, as a reward for my coursework completion I'm going to get that maze 4, and redesign my loop - which, hopefully will eliminate my problems.

That is a unique little experiment. This is my best guess at what happens to the bubbles. In a closed system such as the air conditioning system in a home, if you start adding freon to the system then you can bet there is a leak. They dont use rubber hose though. On these PC's, we use rubber hose or some similar variation. This type of hose is porus, and as heat is added to the equation the hose starts to expand thus becoming more porus. I think that the warm "Or in your case HOT" water forces the air bubbles out through something like evaporation.

Ive only owned one retail cooling system, but after getting the air bubbles out I didnt have anymore to enter back into the system. Now I have built my on system, and air bubbles are not an issue. My question is; Cant you get the air out of your system? Im asking becasue I would think that if air bubbles are a problem then it might mean that you have a air leak that needs some silicon.

lol, I can't get a drop more in. The way the pipes are set up they drain into the rez filling right up to the top when the pump is turned off.

I intend to sort out all these problems by tomorrow night.

That kind of talk could possibly bring WingDing from the depths of the OTHER! Elongated tubes

Thanks for all the replys! May the force be with you all!

That place has some sort of magic grip. I was stuck down there for about 3 solid weeks. I finally managed to escape, but I doubt that I will ever be the same

To save us both time, assume I know EVERYTHING

Ive noticed that you have been up here in the productive section.

I dont know what it is about that OTHER place, but its addictive in some sick way.

To save us both time, assume I know EVERYTHING

Holy crap, thats a shiteload of power. Whats your system? Dont you think 680w is a tad overkill? You could weld steel with that.

Make that 2! I just dont mention the poor little 3.0E as often.

BTW, the 3.4 is in the process of going into an ASUS P5AD2-E premium with a couple of sticks of Crucial Ballistix DDR2 PC2-5300.

I just checked Thermaltakes website. It does have a 3rd 12V rail. Thats 38 AMPS total for the 12V rail

No doubt about the upgrading. Its an expensive hobby for me. More like an obsession! Which card are considering? Did you see the post about the 800XL for $350.00? Im thinking about grabbing one.

To save us both time, assume I know EVERYTHING

You have the advantage! The only reason that I have the extra cash is because im 32 and single. The college girls want to party, and I just want to go home Bottom line is-Im all alone!!!!!!!!!!!!!!!!!!!!!!!!

To save us both time, assume I know EVERYTHING

If that is the case then I am literally SCREWED!

To save us both time, assume I know EVERYTHING

I'm just running an old Corsair Hydrocool, It all depends on the room temp for me, but usually nothing more than 7C over ambient temps.

Average room temp is 28C... average load temp is in the 36-40 range. No case fans at all. Have an old P3 cooler pasted to my video card for cooling that. And that's the loadest fan in the room.

<b>"These are my thoughts, your mileage may vary."

If you want some ideas on a Do-It -Yourself project send me a PM. You wont beleive some of the crazy stuff ive done lately.

Where do you live? What type of climate, cold or hot? You will be surprised at what a fish aquarium pump is capable of pushing. I doubt that you would have to spend more than $35.00 on a pump. Copper tubing is good if you can find some around a junk yard or something of that nature. The hard part about cooling the liquid with some sort of device like your coleman is that the water has to stay in the cooler long enough for it to actually cool. You dont want a really high flow rate to begin with, but chances are that the coleman by itself wouldnt show much improvement. Heres an idea. Most people dont realize this, but a refridgarator is much more effecient when it is full of items. A half full fridge uses more electricty in order to stay cool than a full fridge. Heres my point. Things like Blue ICE packs and even quart, half gallon and gallon jugs filled with water and stuck in the spare parts of your frezzer and fridge will help knock down the electricty bill. If you use these items basically like ice cubes you may find that you can slowly rotate them from your resivior"COLEMAN" to you freezer. Now the freezer is going to lose the effecincy gain because its now working to cool the rotating jugs but it actually just about evens out. This is extreme and not the most practical way to do things, but especially for testing " Extreme OCing" it works very well. If your climate is cooler then you can do something like Folken has done with his system. Look for his name in the forums and click on his sig "MY Precious". He has got some great pics and his setup is as impressive as I have seen.

They probably are, but they are so much cheaper if you buy them straight from a pet store. OF course that means that your probably buying individual parts for your liquid cooling system. I think thats the way to go myself.

To save us both time, assume I know EVERYTHING

If you like the looks of the water blocks then go ahead and buy them. The rest of the setup is really not hard at all. You can get the pump, hoses, and fittings for under $50.00 and if you need a list of parts and where to get them I will be happy to send you one.

To save us both time, assume I know EVERYTHING

Sure, I will put a list together and PM them to you. Then you can check prices in your area. Im sure you will be surprised at how much of a difference in price and performance it will make.
