Unique radiator available....??

[jtroutma]

Just had a though.....

Is there such a Radiator out there that is about 60-80mm wide and 3x as long with intakes at each end?

I have a long tube running out side my cse from the very top to the bottom from my res. to my pump. I was just thinking that if i could find a thin yet long rad. that could be placed in between the res. and pump and put 3 60mm fans in a row on it, that would probably increase my cooling capacity quite a bit with almost no noise difference (quiet fans). This radiator would be an addition to my Aquacoil (which is already doing a great job) and would help bring down my temps a bit more (maybe even keep them down if adding a Video Block to the mix.

Any ideas?

Thanks

there is a heatercore like that, check heatercore4u.com they have one. (I can't remember where though)

fifth product down, I am too busy to acctaully read your post, and all I saw was long rad, so I made this reply.
And its Candian, so you get like $1.5 to 1 of our dollars or more...

Actually reading your post, here are my thoughs.
Chop the bottom off, and put in two more fittings,
use a y splitter at the top and bottom... it'd rock

Thanks for the links guys

WireX:

Looks like a nice rad but one problem; the water will spend about .5-1second in the rad then go straight to my pump so I will get almost 0% cooling out of it, even if I make it parrallel. My understanding is that the more time the water stays in the rad. the more time it has to "move" the heat to the fins, etc. This is why a heater core with thinner pipes would probably work better for me. BTW this setup will probably NOT affect my whole systems flow rate because of how I have it setup. My res. is a the top of the case and so gravity is mostly feeding the water down to my pump at the bottom of the case. See pic....

I want to add this rad. where the hose goes down the back of the case to just before it enters.

I figure that with gravity mostly feeding the water to the pump and the pump pushing the water to the res. then all I need is a heater core to slowly allow the water to get to the pump and if the pump needs more volume then gravity can assist.
I may be wrong in my thinking so feel free to correct my errors.

Brad:
Found that heater core and it looks great! Two problems: 1) Too long It can handle about 4 60-80mm fans. 2) EXPENSIVE!!!

Thanks for pointing me in the right direction.

Any other suggections?!?!?

Thanks

[maskedgeek]

one i made
its like 2in wide by 8in long(including fittings)

clear ends.....

[maskedgeek]

the whole thing

[jtroutma]

Cool!

How much for it?!?!

[maskedgeek]

hmmmmm not sure, what are you gonna be cooling with it?

[jtroutma]

This would be an addition to my other rad. It will be cooling a 1.4Tbird "C" running @ 1.702Ghz (148FSBx11.5)

My Temps on the core are around 39-40C and would like to try and drop that 2 degrees. The difference between my case temp and my CPU temp is 6-7C. Anything else?

[Brad]

masked, how exactly did you make that? did you cut down a heatercore or something?

[ksw]

okey just a question to see if i hav egot it all right.
1 flow rate trough block is very importatn, the more the better?
2. flow rate through radiator should be slow, to dissapate more?

[maskedgeek]

yes i cut down a heatercore that was enormous and made 2 radiators out of it, thats the nicerlooking one of the 2

if your cooling that tbird with only this rad youll have very high temps but if your using it with another rad im sure you could drop a few degrees!, you can fit 2 60mm fans on here, make a shroud of some sort, i supose i could sell it, pm me

KSW:

That is my theory on the whole cooling thing:

More flowrate to WaterBlock the better (up till a certain point where more won't do you any beter. OR you blow up your waterblock

Lower flowrate through your radiator the better (again up till a certain point)

Reasoning behind my theories:

Heat transferes through ossmosis; bot sides want to come to an equalibrium. When a hot object is placed next to a constant cold object, the heat is transfered by ossmosis to the colder object in order to reach equilibrium. The hotter the first object, the faster the transfer INITALLY! After the first few moments, the heat transfer rate will drop logrithmically till it finds equalibrium with the second object OR the enviroment (most likly a combination of both)

In a nut shell; Place a chunk of hot metal in a freezer. The object will cool rapidly at first, then will start to cool slower as the metal begins to get closer to the freezers internal temperature until finally the metal reaches the freezers internal temperature. The greater difference in temperature between the mediums, the higher INITAL heat transfer between the mediums.

My therory capitalizes on both sides of this equation:

Higher flow rate through the block (should) capitalize on the instant cooling benefit from a cooler medium (the water) making contact with a warmner medium (the waterblock). Once the heat is "collected" in the water, it is immediately moved away from the medium you want to cool (the waterblock)
NOTE: Flowrate and surface area BOTH play a vital role in this section; an optimal balance between flowrate and surface area needs to be meet to capitalize on optimal cooling efficence HOWEVER in most cases, more is better.

The slower flowrate throught the radiator is the exact opposite. Since the difference in temperature between the water comming out of the waterblock and the environment (air), the lower the heat transfer between the two (because the two mediums are not that far apart from equilibrium; thus slower ossmosis) SO with this in mind, the longer the water is in the radiator being "cooled" by the active airflow going through the radiator, the closer the water temperature gets to the ambient air temperature being passed through the radiator. (This also explains why you can't get below ambient temperature without another method of cooling, such as phase exchange or pelts). Now, the closer the water temp gets to ambient, the greater the difference between the waterblock temp and the water temp, therefor when the water finally gets back to the block, the greater the difference between the two temps, the more effecient ossmosis affect you will recieve when the water "moves" the heat away.

UHHHHHHGGGGGG! (that was a LOT of typing

OK........ now that I am done saying MY theory about "cooling" does anyone have something against my logic?
Comments? Suggections? Death Threats.....................

[Cyco-Dude]

osmosis is the movement of water thru a semi-permiable membrane from an area of high concentration to an area of low concentration.
i dont remember the term you shouldve used either...

[Brad]

buy any heatsink. run a 20cfm, 35cfm, 50cfm fan on it.

which will perform best?

buy any waterblock, run a 200gph, 350gph, 500gph pump on it.

which will perform best?

[jtroutma]

Brad:

Have to give you points for making my argument simple

However what I was trying to get at was more from a scientific point of view when optimizing the entire setup. Granted trying to make ALL the points in a cooling system optimized to near 100% effeciency is almost impossible, doesnt hurt to attempt to try

Cyco-Dude:
Proably right. It was the best way to say what I was trying to get across.

But seriously guys! Is my theory wrong in a way that I am not aware of? I just remember all these physics and mathematical equations and graphs from high school and college classes that I took a while back and I pretty much remember about the fact that the greater thermal difference between two mediums, the "faster" transference will occur, slowing progressively till equilibrium is reached.

IF that statement is correct and it is possible to control all aspects of our cooling systems, would this not be the way to go?

<- Always seeking a better way to do things and striving for higher knowledge

[Brad]

well, thats just my standard explanation to this argument

[ksw]

yeah brad, but IF you push 250, 350 or 500 gph trough an radiaotr, wich would cool best? my guess is the 250gph, that has the msot time to cool of. but thats a guess.

[jtroutma]

Exactly my point KSW!



Would not a slower flow rate throught the rad. work better than a faster flow rate?

Then we come up to the catch 22.....

How do you keep a high flowrate into the waterblock yet keep the flowrate slow in the radiator?

I think my setup kida allows for both to happen, just by how it is configured (Res. at the top feeding water to the pump at the bottom)

[CptnDipshit]

what if you put another heater core outside your case behind the pre-existing one. If you ran it in parelell (sp) it should cut the flow rate in 1/2 (if it was the same size), and the flow rate of the water block would remain unchanged.

[Cyco-Dude]

"How do you keep a high flowrate into the waterblock yet keep the flowrate slow in the radiator?"

by using multiple parrallel channels in the rad (which is what the BI rads and heater cores do).

[CptnDipshit]

I realize that, This would just increase the effect

[MeltMan]

You want to slow down water in a radiator and speed it up in a waterblock? Use ohm's law. Run 3 radiators in parallel and the flow through each will be 1/3 of normal meeting at the end to be the same as before. Plus, if you run 3 in parallel, your resistance is diminished thus helping flow.

[Cyco-Dude]

Cptn, i was replying to jtroutma lol (he asked the question )
