what do you guys think about this design?

BadPenguin · 02-22-2004, 12:19 AM

*First off, sorry if this is in the wrong thread*

I amd designing my first water cooling system, and I have come up with the attached plan. (pic below) or click here . Will it work? what are your guys thoughts? The pump station is goign to be built out of an old case and contains a 250watt power supply (to power fans). Will 2 radiators like that be efficent, or should I stick with one? also, will a mag 3 pump be able to support this system (350 gph)? any positive/negative comments are greatly appreciated. Please make your suggestions. Remember, im on a low budget, so dont suggest something too expensive

That will work. You'll get a bit more flow and performance if you run the rads in parallel. Better yet, eliminate a wye fitting by having the rads dump into the res.

so do you suggest that from the pump, I "Y" off into both radiators, then I "Y" back into a single 1/2 tubbing and go to the computer? ... and sorry im kinda new... whats a wye fitting?

What i get from your 2 pictures is one design sends warmer water through the pump to be cooled by the radiators, then it moes to the computer, and then your other design is to cool the water from the computer, dump it in the resivor and then pump the cooler water straight into the computer. I have a question abou that seccond deisng.. wouldnt it give more time for the water to heat up if it went to a resavor first?

Also, should I insilate the piping inside the pump station? would that cause any difference?

"Y" = wye. Same thing, but wye is more common among the folks selling 'em. And wye is more search engine friendly.

First pic, with pump-wye-rad-wye-comp-res-pump, is the easiest variation on your original. It will increase your flow, and requires only buying the two wyes.

Second pic, with pump-comp-wye-rads-res-pump, will give slightly better flow. Every fitting impedes flow, eliminating the second wye by use of dual inlets on the res will give a bit of improvement. If you're making your own reservoir, this arrangement is great.

Your water temperature will always be above the ambient air temperature, so insulating the hoses will just hold heat in. Bare hose = good (as I always tell the ladytypes).

The order of your parts makes almost no difference. Rads and the beginning, rads at the end, rarely more than a 0.2 C difference.

what do you think about my final design?

I'd flip the rad/fan assemblies over, and have the fans pull air through them. That way the rad-fans and case fan would give you some good push/pull action.

How much space do you plan between rads and their fans? Two or three inches and a shroud is recomended.

The power-supply: What's its air flow? If it the standard ATX style, flip it over so that it sucks cold air through a blow hole and exhausts to the outside. Or, reverse the fans inside it so that it blows more air into the case (more air for the rads).

Minor details and another photo-chop: a taller reservoir allow you to bleed the air from the system faster/easier. Same with having the radiator positioned so that the outlets are at the tops.

Another thought on the PSU. It appears that you plan to use the case rotated 180° so that you have access to the removable side panel. Will you have the PSU power cord coming off the front? Or modify its mounting?

actually, im goign to mount the radiators on the front of hte case, What I did was remove the front pannel, and im going to cut any space I need for the radiators out of hte front. look at these pictures I took for reffrence:

I must add my .02 on that one. You have not accounted for the flow into the radiators. 1 single 120mm cannot provide enough air to properly feed 2 120mm fans blowing at full speed. There do not seem to be other holes in the case that could feed the rad air. Equal air into the case = Equal air out

didnt think about that.. thanks for pointing that out. Would opening a hole in the top and mounting a 120mm fan in it account for the needed extra air? also, I think I am going with a startoff of a 1 radiator system, and then build up. But i am curious, does it matter where it is, or just as long as 2 120mm blow in?

winewood · 02-22-2004, 09:15 PM

My house is drafty. The air temperature on the floor is lower than that of only 1 foot higher off it. Therfore, any inlet should be as low to the floor as possible. Consider though where your pump and res are placed. Don't impede the airflow into your case by placing the parts to close to either fan. The outlet rad may not matter as much as the inlet. Other opinions may be valuable here.

Meethoss · 02-23-2004, 08:49 AM

You should have the fans sucking air INTO the case through the rads for better cooling, that way you can have only that one fan sucking air out of the case. Better still, add another fan at the top of the case and you've got the two you require and don't have to worry about the warmer air above the case being sucked in.

Also, I'd pump from the res to the pump to the rads and then to the blocks. There's lots of discussion about this but this should mean that the coolest water goes on to the blocks. In the end it's your decision. Work out what is best and have a reason for doing it, rather than doing it cos somebody says so.

SlaterSpeed · 02-23-2004, 12:09 PM

I would have it

Outside of case > 2x120mmfans > rad > Inside of case > 2x120mmfans > Outside of case

A top mounted 120mm would be fine. I find fans blowing through the rad are better and of course you want them sucking cold air from outside the case
