Alright.

My ghetto little project is done and currently leak in a state of leak testing in my garage. I don't have much time at the moment so I'll just post a few pictures and some corresponding words :p: .

First impression of the setup:

A little bit of heat testing with a 1000 Watt heater (ineffective though, the waterblock remained stone cold):

Being help up with a piece of metal, because the piece of wood holding it up got too hot to stay (heater is too vague in heat, waterblock stayed just as cold, will try with a heat gun tomorrow to test it out):

Tell me what 'ya think, I'm off for now but I'll post something a little more comprehensive tomorrow!

Thanks,

very nice custom setup.. but did you make that waterblock or is it a WW?

if you made it can we see internals.

shroud on rad...other than that looks good.

That tubing will likely put a lot of stress ont he CPU socket, so be sure to support it.

Are you planning to run one fan in the front, and one in the back of that rad? Just wondering how you plan on running both of those fans.

Like the guy above me had said def. work on making a shroud, you'll have alot of dead space if you dont. Are you making an external box for all of this, or do you plan on putting it all in the case :)

looking good to me :) but, i do agree that the tubing, because it is reenforcd may be a bit of a pain to bend and angel correctly...thus really putting alot of stress on the CPU socket and motherboard hold down. But, it sure looks good...any idea what the heat dump of that pump is? :toast:

Maxxx, I'm pretty sure it's a custom block he made (He had a thread about it floatin around here a while ago), and it looks to be sorta like a WW

lol at the block on the heater...I could only imagine if that block suddenly started to drip on it.

Always love the ghetto setups :D

1031.nu - interesting sig...used that same pic in one of mine before :P

I made the block. Pretty much the same as the WW. Was too excited putting it together so I didn't get any internal pics. Once it's done leak testing for the first time I'm taking it all apart, so I'll take some pics of that when it's being cleaned out (not running any special liquid in there at the moment, since it's only temporary).

I am planning on making a sound dampened aluminum box for the heatercore/pump/reservoir, and making a different custom reservoir to form fit right onto the pump. I'm shrouding the heatercore, I was thinking about having both fans pulling out, having the heatercore suspended, and having a mesh on the other end of the box with all of the components inside, so the fans pull all of the heat produced in the box through the heatercore and out. (box will have pump/reservoir in it). Anyone see problems with that setup? Also thinking of covering the bottom in foam so that the pump doesn't make too much vibration noise. I'll do a quick sketch of the setup later. The only thing in the case will be the waterblock, and I'll make a bracket on a couple PCI slots so that the tubing isn't pressuring it too much.

Pump is a 36v 3 amp pump running at 12v (can go as low as 6v at least). Not sure what the heat dump is, and its all brass construction. My dad found it in the junk bin at his work and picked it up for me ;).

The internals of the block look more or less like this:

http://img.photobucket.com/albums/v644/Overconfidence/wbb3.jpg

I'll take some pics once its apart, though, and sketch my pump/raddy box.

Currently have a 1500W heat gun about 3/8" away from the waterblock. To get the block hot, we had to leave the pump off, but then after turning the pump on, it became pretty much instantly cool again. Running the heatercore passive and the pump going for an hour or so got temps up to 33 in the reservoir (bottom of block still feels around ambient), but running fans (quite inefficiently, simple running them standing on end pointing towards the heatercore) brings the temps down again. Temps will obviously be different with a direct heat source though, and with properly shrouded fans.

Thanks!

Build/acquire a load simulator (block of resistors + copper plate) and try it with a 100 or so watt load ;)

Resistors will give you the direct heat output your looking for, sorry i cant tell you how exactly to make one but im sure quite a few other people on here can

Bloody_Sorcerer

10-21-2005, 04:53 PM

If you're seriously interested in building one, lmk and I'll help out however I can.

greenman100

10-21-2005, 05:04 PM

same here

it'll be a whole lot cheaper ot run a die than a 1500w heat gun

Overconfidence

10-21-2005, 05:57 PM

Alright. We held a piece of solder at about the same distance and it vapourized, so I can assume that it's running fairly hot (I think 1100F at the source?).

I'm aware that I could run a load simulator, but I don't have the resistors handy (need fairly good ones to run that kind of amperage through it), and my dad borrowed the heat gun from his work and doesn't care about paying the bills :P.

Here's a quick paintsketch of my pump/raddy box (Aluminum frame with aluminum panels on the outside):

Side view:

Top view:

http://img.photobucket.com/albums/v644/Overconfidence/viewtop.jpg

The fans are on the right side, one on top of each other. The heatercore is to the left of that, the pump in the middle, and a projected brass tube as a reservoir. the reservoir will protrude from the top to make filling easy (just a screw-on top will be visible). The rest is pretty much self-explanatory. Tell me what 'ya think! Oh, and on the left side the grey dotted line is where I'm going to put a metal mesh, for the intake (To let air in but to keep the dust out). The fans are 38x120mm tri-bladed rated at 48DBa/110CFM, but can be undervolted to whatever I want.

I'm also going to need a power supply to use for this setup that might be put inside that case (additional modification to the design needed?). Any suggestions? It'll be used to power the fans and the pump (I can do custom rheostats).

greenman100

10-21-2005, 06:00 PM

make sure the fans are such that the rad gets fresh air from outside the case, and you're lookin good

greenman100

10-21-2005, 06:38 PM

ok, but if you draw air across the pump, it will heat up before it gets to teh rad....

Overconfidence

10-21-2005, 07:02 PM

I suppose that's true. Even though after running the pump for an hour left it just as cold, it'll still produce some. Here's a variation on the first one, tell me which one's better (keep in mind that the pump doesn't exactly put off a lotta heat):

Fans draw air the whole way through, and fairly easy to clean out the heatercore. Heatercore has the coldest air.

greenman100

10-21-2005, 07:14 PM

that's better. make sure there is adequate spacing between the pump and HC. also, note that the pump inlet chould be connected directly to the res

ls7corvete

10-21-2005, 09:00 PM

In my design the other end of the mini-case is open (with a screen), so the air can get in.

I've just checking on the internet for the pump that I have... I can't really find anything except for the specs (7.3 GPM @ 10ft of heat @ 32v/3A, and I'm running it at 12v), the price for the motor for one ($150), and the price for the 12v/4A 1.7 GPM model ($180). A similarly spec'd and newer pump by them is about $250. *shrug*

PD pump? Roller style probably. crank that baby up and see what kinda results you get, rofl.

MTBF is a concern but never stopped me.

Carefull with that heatgun stuff you dont wanna warp the base.

Overconfidence

10-21-2005, 09:09 PM

Err, the reservoir is right before the pump.

And the pumps a rubber impeller... But I don't have the power supply to run it up to speed =P.

MTBF?

The base can't get really warped, the base only gets hot if I leave the pump off and let it heat up for half an hour to an hour.

good, I'm just sggesting you keep it that way

Very nice project, i cant wait you to test it with ur CPU, im sure it will work fine with great temps.

But, i think the Heater Core is a little bit small for that monster project :P

Overconfidence

10-22-2005, 09:51 AM

Hmmm. The heatercore is about 8 inches by 7 inches and is 2 inches thick. You don't think it'll be big enough :P? Of course, those fans make it look tiny... maybe you're right. Ah well, I'll have to see how it goes. It's nice though, since it has 5/8" ready fittings already. Pulled it out of an old ford truck for free, can't complain ;).

ever considered your block remained so cold because it was doing just what it was designed to do? dissipate heat???

That's true. Besides, who has a 32v power supply lying around :P?

Hopefully getting around to making a good CAD design of the mini-case so I can buy some supplies and get it together (And need some leftover brass pipe).

Heyyyyyy, mail it to me ;)?

*shrug* How much heat does the beast put off?

Also, do you think that I could use an old computer PSU and put it inside my little box, or are there better options?

That's what I did with my external watercooling box. It runs the fans on top of the heatercore, two other fans pushing air over the pump and one sucking air out, and it'll probably power up some lights when I get everything done.

BTW it's just a 250 watt power supply out of a really old computer, just modded the ATX connector so it runs without a motherboard.

Overconfidence

10-23-2005, 12:53 PM

Cool, cool. I have a 250W PSU lying around, too, I might use that ^_^.

Do you guys think that I should run this stuff in a box that fits underneath my current computer case? I'm thinking of getting the antec p150 and I could build a box to go right under it.

EDIT: 'Nother thing... will I get oxidization inside my components because I'm running a reservoir over a t-line?

I use pure gasoline in my WC setup... no water or anything.

Bloody_Sorcerer

10-23-2005, 03:16 PM

um... why do you run gasoline? Is it the explosive nature? the high volatility? the noxious fumes? The crappy conductivity?

Overconfidence

10-23-2005, 03:44 PM

Whoa, why didn't I think of that before! Duhhhhh.

Still wondering about the two questions in my previous post, and also one more thing:

Will having the heatercore at one end of my setup with the fans at the other end (completely sealed, but it'll be about 1-2 feet away) cut down my performance compared to having the fans right next to it, or having one fan at one end of the mini case and one fan at the other end?

Thanks!

10-23-2005, 04:02 PM

well.. the way i see it.. is if i get a leak im going to be so mad that im bound to kill something... so.. when it leaks and ignites from the sparks... iwill burn to death. therefore i will not have to deal with it.

Overconfidence

10-23-2005, 04:29 PM

Nah, it'll just overheat your system and not explode. Unless there's a leak. Pray for a leak.

... But seriously, some real help would be nice ;).
