How do I make a simple Reservoir?

[Kibler]

I would like to make a simple Reservoir for my pump. Doesnt have to be anything fancy or look real slick....

I have heard people talk of underground electric boxes or something? Anyone have a picture of one or ever used one?

I assume you have to drill holes for the pump power cable and the intake/output tubing in something like that? What exactly is used for a sealant?

Thanks,

Kibler

well

practically anything will work for a reservoir. the only thing a reservoir is, is somewhere to hold water. i mean, you could use a tupperware container if you wanted to for just a bare-bones-doesn't look-pretty-but-works-fine reservoir in theory.

sure, drill the holes, use rubber gaskets or silicone sealant to seal the gaps... i know alot of guys use PVC plastic boxes. can be found pretty easily at your local hardware store...

does that help?

That's an electrical underground box, of the 4x4x4 variety ($7 at Home Depot). I originally had that, then looked at Danner Supreme Mag drive's measurements, returned the 4x4x4 box for the bigger 6x6x6 kind, $13 at Home Depot. At the moment, it's lonely, I ditched it for an old aquarium my parents used to use to seperate sick fish from the bigger tanks, haven't had fish for a few years so I managed to snag the aquarium without question.

Morale of my story, plan, plan, plan ahead.

rad. thats exactly what i was talking about when i said PVC box... didn't realize they called it an electrical box. hmmm... learn somethin new every day i guess...

I used a 4" piece of PVC drain pipe with an end cap glued on one end and a threaded cap on the other end (for filling with water). My pump sits inside the res and the unit is very quiet. The material is easy to drill and glues fast with plumbers PVC cement.

[Kibler]

Ve6jhc yes that is a good idea as well...

I tried placing my radiator between the pump and the water block intake (so water flows through pump, then radiator, then cpu, then back to pump) instead of my old setup that had the radiator after the cpu.

It seems to perform a lot worse actually.

Is this normal? I was thinking you would want to have the water as cold as possible when it goes into the water block and that the coldest the water will get is when its spit out of the radiator....

I had a simlar situation, I went down to my local Autozone and picked up another oil cooler for about 23 bucks, I'm not worried about space, and it stays at ambient.

[train22]

what does the electric PVC or box, whatever you call it, do better than a tubaware? Why is it better to have the water inside that box and why does it need electricity? (Power)

Well from what I understand, the purpose of the radiator is to remove heat from the water. If you pump the water through it after it has gone through the CPU Block, there is alot more :mad: HEAT, and is more easily removed than if you had the water pumped right from the pump to the radiator.

Just my :rolleyes: 2 Cents, *shrugs*

I have had pretty good luck with the CPU first.

Sorry for double post, quoted wrong person, doh ;)

Unless you are using extreme cooling, the water will get no cooler than ambient temp. The radiators purpose is to prevent heat removed from the cpu heating the reservoir. Whether the radiator is placed before or after the cpu doesn't matter as long as the temp of the resevoirs water doesn't go above ambient. Blowing a fan across the radiator might be necessary to accomplish this.

not entirely true. most of us have a submergable pump that sits in our reservoir. the pump will keep that water warmer then ambient by several degrees all by itself. pumping from the reservoir to the radiator and then into the CPU is a better idea so as to remove whatever residual heat from the water was accumulated in the pumping process.

that whole last sentance is grammatically screwed but i'm too busy to work it out. you get what i mean. :)

[r0ckstarbob]

er... i mean "US" as in "...us overclockers". personally i'm aircooled but have alot of experience with watercooled systems.
:D :D :D :D

[Kibler]

Ok so I am still getting horrible temps! I switched the radiator so it is now directly after the cpu in water flow terms...

It will idle at around 31 C when left for hours. But the second you do anything the temps jump way up over 50 C!

I used to have this exact same setup but with a little Rio 180 pump. Now I have a 275gph pump instead, only difference int he setup. How can this make temps higher?! Is the water moving too fast?! Huh?!?!?

Well I am not a pro at this by any means, but I would rather have the 'lil bit of heat the pump produces go through the CPU, than to have all that heat sit on the pump. I can only imagine what that kind of heat:mad: can do to decrease the life of your pump.

No pump, No puter :(

[dimmreaper]

I use the tank on the back of my toilet, and everytime I flush I get nice cool water in the system. The only hard part was pumping that water to the next room and back, I had to use a 2500GPH diphram pump . . . . .

I actually used a 2 quart plastic jar, with holes drilled in the lid for power and the water lines.

gee whiz, i never thought about that. you're probably right... i'm sure 7 or 8 degrees above ambient would probably prove catastrophic to a water pump...

...... riiiiiiiiiight



kibler you had it right the first time.

cpu ===> pump/res ===> radiator ===> cpu

you're going to have to give us alot more information if you would like help in troubleshooting your system down for heat. at this stage it's likely that theres more then your watercooling setup thats askew

[Kibler]

I have an Abit KT7 (the original!) with a tbird 1200 on it.

I have a Maze2 block, the Danger Den cube radiator, and a 275 or so gph pump (it was from the local hardware store, its locked inside my reservoir right now so I cant really look at it).

I have a two Panaflow 120mm on either end of the block. One is the L1 (a low speed quiet model) and the other is a higher speed model, not sure which one.

Now I used to have this setup with everything the same but with a Rio 180 pump, it did quite well.

I then went nuts and made a bong tower cooler with the more powerful pump, again it worked well if not better but I wanted something more portable.

So now I am back with the setup I describe above. It can get down to 30 C or so but the second you use the cpu it jumps up and goes above 50 C and then locks. Normally I would try to reseat the waterblock and check the thermal paste (I use artic silver II) but when I switched from the Bong Cooler to this setup I never removed the waterblock so I know that cant be the problem.

I have now tried it with the radiator on either side of the cpu with no noticable change.

hmmm...

*wheels clickin, wheels clickin****

well, check this post out. heres a guy who was having similar problems.

gimme a little bit and i'll get back to you. until then, peruse the post and see if there are any similarites. you never know. there might be a solution in there for you.

check it

http://forums.overclockers.ws/vb/showthread.php?s=&threadid=34178

and i'd check that waterblock mounting just for good measure. these systems are tweaky that way. try to cut any corners at all and it'll nab ya. never know. might have just barely jostled it loose or somethin. can't hurt to check.

[CrazyDave]

First thing, is there anyway that you can check the pump even tho it is locked inside?.

Even though you haven't detached the waterblock, it can't hurt to double check it... although waterflow definately sounds like the problem here.
