A while back I completed my computer and ive been running ir fine ever sense. I noticed that when I do overclock, it tends to heat up rather quickly. I overclock to 2.310Ghz (real) at 200 or 220 FSB. And I ve noticed that the cpu's been running hot. around..55C on idle..and can reach beyond 62C under load. I really need to lower my temps to atleast 40c or lower. I was thinking of using watercooling. Ive began desiging a waterblock for the cpu. AndWhat is the most efficant design? isa it a maze or something? or can I have like fins poping up from a milled down peice of copper? I was thinking of making everything myself, excpet the pump. I seen a nice pump at petsmart for $15 that moves 75GPH. The radatior however..I dont know..I was thinking of desiging my own by wrapping copper tubing with AL fins (from the kitchen or use a heatsink). I dont know if my dad can get me one from an oldcar..but that maybe too big.. or maybe not

Now I'm going to be cut and dry here, lowering your temps will not be done with some ghetto pump that's pushing a fraction of what you need and a radiator that has poor heat transfer compared to a heater core/rad that is actually needed. Designing your own waterblock wouldn't be a bad idea, however if you don't even know what designs are efficient then don't even try right now. Look around at what companies are selling, and what the best blocks currently are.

If you seriously want to watercool your system, just browse through the Extreme Cooling section of this forum. Practically ALL your questions are answered there, and then some. Suggestions don't even need to be made right now for what components you need because they've been made countless times. Read and search before you ask, you'll save yourself and everyone else some time.

If all this gets too expensive, there's always a luxurious air cooled heatsink waiting for your processor. For these suggestions, look in the Air Cooling section of this forum.

Another one of these threads....

What kind of tools and equipment do you have access to? My guess is not much since you're only 16...

The design of your waterblock and its effiency depends just as much on the rest of the parts in your system.

That radiator you're talking about will give you ****ty temps regardless if you cool with water unless you use ALOT of copper tubing.

That pump is garbage unless you specifically design a system for low flowrates.

From the sound of it you're planning on using a hand drill and/or dremel to do this. Don't waste your time. You'll end up with alot of grief and aggravation (not to mention one fuggly waterblock) for sub-par cooling. I would suggest you just find a decent air-cooling solution in your price range and call it a day. If by some off chance you DO have acess to a CNC mill or similar equipment you would still need to do alot of research on your own beforehand. I'd say a nice bench drill is about the bare minimum you'd need for any kind of discernable block design.

You want ghetto? http://www.overclockers.com/tips128/

That's probably how yours will turn out from the sound of it, if not worse.

Dude - that is somethin' that makes people from the ghetto say "That's ghetto".

Lemme rephrase - I think the "African queen" project is ghettofabulous.

Im think about water cooling at the moment to hush my rig. The sound of even 5 fans makes my head spin. From what ive seen, and what I see as the best block design is simple:

- Block of copper, fairplay thick, contact with CPU.
-Shroud contain the water flow area has an inlet and an outlet. This way a constant suplly of cool fresh water is always being supplied, without goin round some stupid maze, and doesnt slow the flow rate down.
-goes back to rad, res, pump and away we go again.

I guess to increase the surface area, much like a heatsink you could have small grooved fins inside the shroud, and even on the outside:


see?i even took the liberty of drawing one for you. even painted the backgorund yellow. I see this as an effective block. You would need decent piping for a good flow though - see Digitalworlds Gallery for appropriate pipe size

haha i like how his final temps are higher than his air-cooled setup. nice copper tho'
dave suggests window shopping here: http://www.xoxide.com/watcoolcas1.html

Nerdz, the guys are mostly right on this one, even if they sound a little overly down on your ideas.

Without getting into the whole thing, you need to understand that flow rates for pumps are not the most important specification. "Head" is much more important when determining the basic suitability of pumps for water cooling.

"Head" is the measurement of how high the pump is able to push water in a verticle column. In other words, not how fast, but how strong it works against resistance.

Now 75 GPH isn't all that bad a flow rate, but that measurement will be a "static" measurement of the mximum the pump can do against no resistance at all. You concept of a copper tube radiator has been done, and it can work fine, but if it's going to be passive, then it will need to be about 6 feet in length, and that is going to add a lot of resistance and will require a pump with a good head rating. You could get away with a lot less copper if you add your fins and fans. But again, unless the copper is cheap, it's going to cost you as much as an old heater core and the heater core will work better.

It isn't what your wanting to do that's not well thought out. It's just a few of the angles in how you plan to accomplish it that has some of the guys making alternate suggestions.

And there is a great amount of info in the forums, I will be glad to help with specific questions as will several of the others.

Good luck, yell back right here if you want, I love recorded history, it keeps me on track when alot is going on.

Nev_payne, as for you, it's easy to see that you have been doing some reading.

Nothing wrong with your concepts as long as you can get everything done, and in a balanced effective way.

Dave, I am not so fond of Xoxide, their selection is too limited for my tastes. I prefer to stick with the big guns in this part of the industry, Swiftech, DangerDen, Innovatek, and an up and coming favorite looks to be Zalman, and someone we will be seeing more of soon, Frigus Engineerings' "Intimidator" series of water blocks. Other companies have entered this market on the idea that they could produce components that were effective, reliable, and inexpensive. The problem is that the moment they finally reach effective and reliable, they forget all about inexpensive. I'll be watching these guys, I like the idea of $35 - $40 water blocks that work decent and are well built.

Intimidator Water Block review

Oh, and in the future guys, do us all a favor and start your own topic so your not highjacking someone elses, it's easier on us all

thnx nev_payne for the idea. I was thinking of doing it somewhat like that except carving the copper out and leaving groves all around.

And I have access to a drill press, dremel, uh recporcating saw, hack saw, and the drill press in capable of milling, cept we dont have the vice to hold the pieces in place. but I do have a machine tool shop in my school. I have a couple freinds in there that could do it for me if I give them the plans and copper base.

and heres the pumps at petsmart http://www.petsmart.com/global/produ...=1082145319735

they have a 500GPH model to and a 250

and Ive been thinking about the radatior design a bit. A coil of copper tubing, but at each end there would be fans. They would blow into the inner portion of the coil to cool it off so that I would have cool water coming out. One fan would blow in, and the other would blow out. I do have a couple 80mm fans lying around and I recently found some 120mm and 90mm for like 99cents each. My waterblock design wouldnt be to complicated,but would be good enough for decent cooling.

andI was thinking also for the pump, a windsheild washer pump.

If you are going to build your own stuff and use pumps that arn't the norm, then you really need to watch out for a little thing called "duty cycle" (this mainly applies to the pumps) A windshield washer pump was designed to run at or below a 6% duty cycle, in english that is running for less than 6 min/hour. I don't know about you, but I tend to run my computer for more than 6 min an hour. There are some really cool benefits for doing it all yourself, but you will get burned if you don't do your research!!!! As for a block design, take a look at procooling. There are lots of DIY blocks there, if you can get past all the bashing that goes on there, then you should be able to find something that you can make with the tools you have.

Good luck.....

For the better of your watercooling experience, going with a sub $20 heater core and using your $1 fans on it would be a huge improvement over copper tubing. This will save time, space, and money due to the high surface area a heater core has. The thin tubes in a heatercore transfer a whole lot more than those huge 1/2" or 3/8" tubes you would use. Many awesome heatercores have been recommended in the Extreme Cooling section here, just search for "heatercore".

Recommended by Zenn, if you want a PetSmart pump than you better shop smart and go with a Danner Mag pump found |_h_e_r_e_|. My suggestion would be the 350gph one if you're going to be running a normal sized setup.

For a good pump comparision, read over THIS article. For a review of the Mag 3, click HERE. If my vision serves me correctly, there weren't any windshield washer pumps reviewed...hopefully that tells you something.

Good luck designing the waterblock, it appears that you have a good array of tools necessary to do so. Use them correctly, and remember the quote at the top of your screen .

In that case I would suggest either a design like that Intimidator block that Ic linked to (channel design), a simple maze (both probably not very possible with a drill press), or (and probably your best bet)....a #rotor style waterblock:

Check it out....simple, cheap, effective, and right in your "equipment range" with blueprints already included. What more could you want?

hmm I was thinking of the radiator lately..and I was wondering..if I did do a ghetto radatior and put a pelt on each end to cool off the water would it work? or if I got a radatior and put a pel on it to cool it off, would it cool off the water? OR If I got a pelt or 2 and put them in the water reservoir to cool the water off, then I wouldnt need a radatior. I would have sufficant current to supply them..I just need to make room. I already made the reservoir and it came out pretty good. but as a temp solution I recenlty bought a thermal Take slim volcano 10+ that was all copper..it works pretty good and allows me to OC w/o worrying about temps. I still want to get lower though

How were you planning to cool the pelts?

Going ahead and throwing peltiers all over is the same as throwing just as much heat as cold those pelts produce around. Pelts get hot on one side, cold on the other...so you need to cool the other side, which just puts you back in a continuous circle.

Last time I'll say it...just go with some heatercores, they're low priced and are probably the best radiator solutions out there. Buy 2, 3 or even 5 if you want, just go with a heatercore solution. Large copper tubes will get you no where if you want efficiency.

A big heatsink in the back with a couple cheap-o- 80mm fans

and Ive been calling around places..(still havent found the city dumps number yet lol) to automotive parts and one place said they can get me one for $30.. my dad said he could get me a ac coil. He said its the same thing but I kinda forgot the name of it lol. He said its as big as my case which is 17 by uh..17? but I dont care..just as long as it cools the water anddoes its job.

Lately its been hot and muggy around here. Ive noticed my mobo temps are a bit higher than usual.

Ive still been working on the resivior and there are some leaks. Ive used acrlyic glue. By mixing acrylic and acitone and leaving it covered for 24 hours it gave me nice and goopy stuff that works pretty good and bonds to everything.

Anyway I'll probably do a bit more research on watercooling to.

My dad doesnt aggree on the idea of mixing water and electronics together. He says we have to much time. bah..in our world of high temps, they do mix

What you're talking about is an "heat exchanger" out of the air conditioning loop of an auto...it's made of alminum and it's a worse no no than water and electronics...

Hey um, Nerdz.

You know it wasn't that long ago that all water cooling was DIY with a few notable exceptions like some of the Cray supercomputers. Actually even they were DIY, but at a very professional level. Anyway, what I am saying is that water cooling has advanced far beyond those days.

Now it's up to you. You can take advantage of what people have already learned the hard way, or you can ignore the fact that everyone else already has wheels, and you can go re-invent some yourself. But if your going to go your own route because that's what you want to do, then please understand this. Your probably going to screw something up along the way, or have to try several times before you get to where you want to be. And as long as everyone knows your trying to blaze your own path and your willing to accept some hard knocks along the way, then really no one here will bother you about it.

It's your path, what do we care if it starts in the same place, goes to the same place, and runs right along side the well worn trail that others have already made for us.
