A few Q's about W/C

[Mindless-Moron]

hello again, i've got a few question about watercooling, recently i've been leaving my pc running 24/7 its been off 2 or 3 times in hte past 7 weeks, i was wondering would it still be safe to watercool with my pc running so long, what with the water getting warmer, for referance i was planning on using a pa120.3 with 3 7v panaflo L1A's and a fishtank for a res (its fairly large) and an AQX pump, this should all keep the water nice and cool, the pump shouldnt fail, should it?

Ok the next bit is setting it up using a fistank, which i will probabbly have to build a sort of wooden base around for safety, should i submerge the pump in it to make it quieter (it would also require less utbing since its in the res so jsut leave the "in" section of hte pump open) what about powering the pump, how would i reach a molex that far? also how much tubing will i need (in feet) its in a stacker, cooling cpu vga and chipset go to the rad out the back of the case to the res (sitting within a few inches of the right hand side of the case)

btw the reason im using a fishtank is because i found one sitting in the shed doing nothing (aside from spawning mould) and im too tight to fork out £20 for a tiny little res, and big res better temps, yes?

should i actually bother going and spending money on a dremel to cut into the bottom of my stacker, when i already have the tools and most of hte material to make a nice wooden radbox? as for powering it, surely i could get a small enermax microatx psu, swap the fan for a 7v panaflo stick it on the back of a radbox, short the green wire, and hey presto, if im too lazy to start it manually i could also buy one of those one click turn everything on with your computer multitaps/surge suppressors.

oh yea and in which order should the loop go?

from res > pump > cpu > chipset > gpu > rad > res ?

or

res > pump > rad > cpu > chipset > gpu > res?

Too many questions at once

Water cooling is great for 24/7, even with peltiers for the more adventurous amoung us

The PA120.3 will handle just about anything within reason, Marci has the lot on test on XS with a 2 x peltier water cooled setup, and I think it sits near 33 degrees C.

I don't think that the AQ50z takes to well to being under water... (other pumps can, but they will dissipate ALL their heat into the water).

Make a box, if you don't like it - burn it. That's up to you

Folks say the order of loop isn't that important these days. But I think blasting the CPU with the pump (1st one) would make sense.

i run my pump to my rad, then the rad to the cpu. Im using pelts in this build (kinda worried) , is there really a need to submerge if your building a box?

With peltiers I think that it's a good thing to worry. If you don't worry you are probably more likely to blow stuff up!

Take precautions, and always atleast double or triple check everything, and you should be okay

I would say pump to rad then to cpu that way your going to get the coolest possible water to the cpu just after its been cooled by the rad

 

[stocky]

Maybe, but after a few seconds doesn't all the water mix and become about the same temperature anyway...

I'm just going to loop my peltier rig by convenience. Which ever leads to the shorter, tidier tube setup I think

yeah, I saw that somewhere too actually quite a while ago - they tested water at different parts of the loop and found it was more or less consistent.

 

[Phil Stanbridge]

It really doesnt make a jot of difference which way you route your tubing these days. The pumps are so powerful that the flow rate counter acts any issues that you would have had in the past, especially so with the AQZ 50Z and the DD5, incidentally the AQZ 50Z is still the pump of choice for many. I would say route the tubing for convenience. Some loops are complicated, make it as easy as possible.

 

[Master_G]

The simplest tubing route is often the shortest as well, which is a good thing.

ok more questions, additives, what ones sohuld i put in it, the only onei can remember is watter wetter, but i belive it supposadly smelt like stale urine. and i intend to get some uv dye, i can't foresee that being too much of a problem. but hte most important question is, being the lazy sod that i am, and not being bothered to cut holes in my stacker just yet, would the swiftech radbox assembly support the weight of a pa120.3 with 3 fans on it?

Additives are up to you mate - I stick to a small amount of anti-freeze.

Be careful of other additives as some are poisonous.

The rad box could hold the weight - but connections like that are only as good as their weakest link (screws, case etc...) not good if the balance is not right - I would suggest mounting the rad verticle with the top 1/3 being connected to teh rad box - any different is asking for a world of hurt I feel.............. could be wrong though as I have never tried. Don't forget RAD will be full of water too.

PS: as a side not and off topic - this was post no 1971 for me coincidentally the year I was born.

 

[Mindless-Moron]

is that it just antifreeze? oh and i intend to use distilled or whatever it is water cos i can get that for free and it does give some peice of mind.

LOL no mate a 5:1 mix with distilled water - 5 parts water to 1 part antifreeze.

Added note.... NONE of the 12vdc pumps available here are submersible. You'll kill the pump should u try. 50Z, D4, D5, DDC, Mac, CSP750 - all run inline only.

5:1 sounds a bit of a heavy mix... that's 20% by volume... remember the more you add to water the bigger the potential hit on performance. 5% zerex by volume is enough for anticorrosive purposes, and as that's a heck of a lot less than antifreeze it should result in a higher thermalcapacity of the coolant.

 

[Mindless-Moron]

cool shoudl ahve some money to buy some more parts soon, i doubt im gonna use hte fishtank for lack of space on desk or floor. was thinking of either the dd double bay res, or the thermotube, but it is rather expensive is it worht it?

also how much tubing would i require (only doing hte cpu for now but will expand) its a stacker, so roughly the same size as lian li pc75.

gona get the pa120.3 but since fans cost like £12 each i thought use a couple of hte 120's i ahve sitting about then buy 3 panaflo m1a or l1a's whichever the quieterone is.

 

[stocky]

Well, as I got the dB readings sorted for the fan experiment you can compare them and see which one will be more quiet! :B

I personally like the tube reservoirs, but I think it just comes down to personal preference.

I have a Stacker, but have used quite a few foot of Tygon, more than I anticipated. For just the CPU you'll use a lot less, but it does really depend on how far apart your components are - as that makes all the difference.

the best order is pump> Res> Rad > split the flow! (y splitters) then cpu/gpu/chipset all get the same temp of water. join the flow and back to pump. A pump creates a small amount of heat so its best to have this before the rad.

 

[boardy]

Why if the pump creates heat would you put the res after it? Res at the end of the loop I always put then the water is cooled by the rad after going thru the pump.

pump creates heat, also water is warm from waterblocks so then send it through the res which will help get rid of some heat(bigger the res the better) then the rad - which gets rid of the rest of the heat.

 

[Mindless-Moron]

stocky how much tubing did you use, im only plannign on doing the cpu for now but i will eventually add a gpu block and maybe a chipset block.

got a link to the fan experiment.
