Large resivoir for increased cooling

[RichPLS]

Yes, but rad grill is probably copper and lead...

Thanks for your input.

I'm building my system in a couple of months, when you know what gets
release. Right now, I'm searching the forums for answers. Because I know their out there. I heard good things about the swiftech MCRES
reservoir. I was only concerned about the size. But in reading different threads, a lot of overclockers use T-lines. Which make the swiftech large by comparison. Anyway, it's fun doing the research.

I was thinking of building a custom water resivoir for a water cooled system in the the range of almost a gallon. Has anyone done this or know if it would increase cooling efficency?

I have considered an infinite reservoir setup. Get rid of the pump and radiator and just plumb into the house water main.

Funny, i had a similar idea after finishing the water pipes in our house... must be the mapp gas. :lol:

Although now that i know how to weld copper tubing, my next watercooled computer is going to have "in-case" plumbing... 😀

Hello Clue69Less,

Nice idea until you loose water pressure to your house or apartment for what ever reason or the area you live in is under drought conditions.

or in my case, city water bill is fixed rate at $49 month... :twisted: :idea: :lol:

And on the coastline of the Gulf Coast... drought effecting water supply to the point of shortage possible, albeit unlikely... 😛

No problem. In the first place, I have never had that happen anyplace I've lived. But it would be trivial to fashion a failsafe flow meter or pressure transducer that would shut down the computer if water flow/pressure was lost.

From a purely theoretical physics point of view, a resevoir is something that the thermodynamic properties do not change very much when, for example water, is taken from or added to it.

This means that a large resevoir is better since you want the resevoir to be essentially room temperature no matter what amount of hot water you dump into it or cold water you take out of it.

The radiator would be needed to minimize the effect of dumping the heat into your resevoir.


P.S.
Hot water goes in the top, Cold water comes from the bottom....

For equilibrium, as people say it does nothing. However if like me you only use the comp for a couple of hours and then switch off then a large res can have an impact.

A 100W proc would take about 1.4 hours to heat a gallon of water from 20deg C to 60 deg C. Obviously the more water you have the longer it takes. Eg, 5 gallons would take 7 hours to get to 60deg.

However, once it got there you would be pretty screwed. Also, because heat transfer depends on the temp difference, less and less heat would get transferred from the water block to the hotter water.

Getting an alu res is a nice feature, but if you want performance then another rad will make much of a difference!

It is interesting that you mention a five gallon reservoir. Right now i am actually planning on building a seven gallon reservoir that will sit on the floor next to my computer. When it is finished it will weigh about 115 lbs. with 60 lbs of that coming from the aluminum reservoir. Since i only run my computer for a couple hours a day i am pretty sure i won't have any problem with this overheating. In fact it is probably way overkill but then whats the fun of building your own water cooling if it isn't overkill.

Overall dimensions will be 34 inches long, 5 inches tall, and 12 inches wide.

I wonder how many hours it will take to heat this beast up.

LOL Neo good job at resurrecting a 2 year old thread.

hahaha 😉

 

[rubix_1011]

Just make your own if you aren't satisfied with store-bought res's. Seems to work well for me.

Edit: Yeah, Kudos for drudging this one back up. 😉

Edit for explanation

I didn't even notice that this was a two year old thread. This is the first thing i have ever really done on a forum.

This is the picture of the first water cooler i ever built it held over a gallon of water but didn't have enough surface area to dissipate all the heat so i had to add the fan.

No worries. I was just yanking your chain about the age of the thread.

But if you really want to go big I know a guy who built on using a plastic 55 gallon drum that he got from work. It is fully sealed ( not permanently though) and located in his basement. His cpu it usually about 5C lower than the amient air temps in his computer room. but he has to keep an eye out for condensation too top things off.
