Need help from the Watergods...

Mikey Boo · 07-30-2002, 02:29 PM

okay here is what i have to deal with: 2xbp6 with 2x366z and the chipset and a msi649d with 2x1.0 and chipset. everything is goin to be rackmounted due to space and i wood like to have one coolin setup for all the comps and further addonz. im just not sure on what pump(s) and rad(s) i should by due to the size of the system. what i have for a so called plan is to have the out put of the cold water, to be separted 3/more times to the comps and then return the same way back to the reservoir(i figure about 3liters should do it) just a thought should i maybe consider 2 rads? one b4 the cold water goes to the comps and one after the comps goin to the reservoir? any help wood be great. once i get the first set of my blocks, im goin to take picts and post them.

Well first of all in given setup you would want to run everything in parallel. I would say multiple radiators would deffiniatly be a good idea here as well as probably 2 large pumps in parallel (like Little Giants, or Maxi Jets). I think this article http://www.overclockers.com/tips915/ should give you some good ideas.

thanx decodeddiesel

it looks like ur the only guy with input here??? well i got a cheap/crappy rack ( $35 loonies ) and ill have a case by the weekend. so then i can figure out where im goin to put everything.

Just a flyer, but I think that putting 2 rads in parallel after the comps would be the most efficient. Keep the resevoir as cool as possible. That's probably going to be your biggest heatsink.

Here are some tips:

Rads always go in parallel. Blocks always go in parallel. Pumps ALWAYS go in series unless they are volumetric (yours won't be).

Follow those rules and you will do good. If you want a good powerful as hell pump, look here: http://forums.procooling.com/vbb/sho...&threadid=3884

Good luck. Sounds like a few BIXs in parallel or a very large truck radiator (think Ford F350) might do it for you with that many machinas. Put it after the blocks and before the res. It'll do you best.

Good God, I can't imagine *two* Little Giants in any setup. Besides, I bet you can buy a single pump that will perform better for less money. I have the Little Giant catalogue at home, so I'll take a gander and see what I can find. Also, if noise is an issue, than watch out, these things are nowhere near silent. Finally, I'd be tempted to run the blocks in series... you may hurt your flowrate, but your fluid velocity in each block will still likely be higher.

Sound like a job for The Quiet One pump by Rainbow

You NEVER want to run blocks in series. You get: -> cold -> warm -> warmer -> melted chip -> radiator.

In parallel they will all have cold water hitting them. Your flow might be hampered, but your chips will love you for it.

airspirit · 08-01-2002, 03:26 PM

Try a NPU500. They pump obscene amounts of water, with a 5/8" inlet and 1/2" outlet. They run silent, as well (inline). They can also be submerged if that is your thing, and they come with a rubber housing in case it smashes against anything during installation.

These are constant use pumps. I've had really good luck with mine. Plus unlike most pump figures which are blown out of proportions, the figures they show are understated.

bigben2k · 08-01-2002, 03:42 PM

Nice pump, but I wouldn't spend over $100 US for any pump.

As for the blocks in series, that's just fine: the flow of water is too fast to allow the last waterblock to overheat and cause damage. It is however, awfully restrictive, to the overall flow.

In parallel, you get a lot less flow to each block, but you get more overall flow.

It's a balance thing, where you have to figure out which block needs more flow.

Please let me know what single pump would perform (ie produce more PRESSURE) than 2 little giants? If you look at the pressure curve of the little giants compaired to other pumps you will see it is very favorable. If these were to be coupled with 5/8" tubbing or better yet 3/4" tubbing, it would easially be able to deliver the kind of coolant pressure/flow he would be looking for in a large multi-computer/multi-CPU rig as well as provide a lot of scalability for any future additions to the setup. Also, I have found little giants, when properly bleed or air and the vibrations isolated are very quiet, and as a whole these pumps are extraordinarially reliable.

airspirit · 08-01-2002, 04:43 PM

I agree. Over $100 for a pump is obscene. I picked mine up for $80 at an aquarium store. The way I figure is that you'll pay a little more but you'll get an extremely good pump that is tested for years of continuous service. I think what sold me, though, besides the obscenely high flow rate, was just how rugged it is. You'd be hard pressed to damage this pump. Plus, it is sealed EXTREMELY well ... it is not going to leak unless you shoot it with an elephant gun.
