sorry but I can't make up my mind.

the question: 1xRX360 or 2xRS360 ??

u see.. I am currently running cpu and gfx on the same loop.. with a double and a single in series.. but summer in greece can get really hot as you can imagine.

at the moment at load... gfx temps go to 60.. but.. unfortunatelly it also brings my cpu temp up to 60... and within 30minutes... I crash to desktop.
I don't wanna sacrifice my oc just because it is summer... so I decided to add some extra rads.

Now my budget is 100pounds.. so my thoughts were these:
1.i keep the double+single to cpu, from there into the RX .. then to gfx and back to res.
or.
2. pump--RS--cpu--RS--gfx--res

or.....i place the rx after the gfx.. to cool the water before it goes to the res.. and then from the res.. recool it with the double+single before it hits the cpu...

Am I getting confusing?
 
You might be better off running 2 loops, one for the gpu & cpu, also if you need to remove any parts you wont need to drain the whole system.
 
yeah I know.. but I destroyed my second pump by accident... so I dont have the option really.

I have been busting my head over the last week... and my budget being tight.. these are really my only options.

1xRX or 2xRS

I just cant make up my mind.
something tells me that quality over quantity is better...
but again.. with the 2 RS it gives me the option of more possible uses in the future.
i.e. second rig.. 3rd loop etc..
again with 100pound I can just stretch to get an RX480
but will it do the trick?
that is.. drop my load temps atleast 10 degrees?
it's the gfx that is killing me
 
What are the rads you have at the moment? The double and the single?

It would probably be easier for you in the long run to get 2 RS's, like you say, more possibilities in the future. But if the 2 rads you already have are pretty good, you may get better results using those with 1 RX. Make sure you get some decent fans on them too :)
 
the double is a crossover from xspc which they dont make anymore. thickness wise, it sits between the RX and the RS.
the single is a black ice.

for the fans I am decided on the xigmatek.. 1500rpm 60cfm I think.. but I use a rheobus so normally I set them to around 800-1000rpm.
I am more concerned with the noise than the extreme performance.

mm.. 480... mm...
 
How are you mounting these? If there's space and they're all getting fresh airflow, two low quality radiators are likely to outperform one high quality one, within reason. If you're stacking them (:p), the thick one is almost certainly the better choice.

What's your pump? If it has a low pressure head, fewer radiators may well perform better than many. If it's a laing ddc you can probably string however many you like in series with no real problems.

Photo of the case where these are going to be fitted please?
 
hey.. tnx for joining my thread :)

pump is that laing monster s ono flow probs here..
mounting would be external.. since I am using a cube for case..

I'll custom make a skeleton shroud that will be mounted to the side of my cooling unit.

it's all about how to setup my loop.

pump--triple-cpu--double--gfx--triple--res-pump

or.. pump-quad-cpu-double-gfx-res

really cant make up my mind..

here are some pics..







 
Nice work on the radiator box there. It would be a reasonable amount of effort, but you could consider removing the psu and mounting a 240 radiator on the side instead. The 120 might be moved to the back, hard to tell if you can fit that or not. Perhaps move the 120 to somewhere in the lian li if not? This would particularly suit getting a single 240, as temps would go down without needing another box.

Obviously the box needs to be powered, how about running the fan controller and pump off a single 12V line wired to a socket on the back of your box, and wiring a molex to a matching socket on the back of your lian li. 6.3mm headphone jack would be my choice, but I don't know offhand their current rating. Whatever method, running a 12V/0V line from the main box would give you more space in the rad box, at the cost of one more cable which you could wrap around the tubes anyway.

I'm really fond of matx systems but sadly don't have one at present. My next computer, probably many years in the future, will almost certainly be matx with radiator box attached. Fair few things to get done before I can try assembling a new computer though :(

Anyway,

Normal rule of thumb is reservoir before pump, then minimise tubing length. The entire loop tends to sit at the same temperature once it reaches equilibrium, and it reaches equilibrium quite fast. Loop order matters little enough (under a degree at normal flow rates I believe) that it's generally advised to do it based on convenience.

Longer tubes going to cpu and gfx tend to be helpful for moving/changing components for example. I tend to connect the gpu directly to the cpu with a very short tube, but more fool me for doing so. As a consequence, my loop (will be) pump/res - 240 radiator - cpu -gpu - 120 radiator - pump/res but I've not worked out which direction to send water in yet. I'm inclined to have the cpu early on because I foolishly believe this means the cpu gets higher pressure water and I'm using a restrictive block, but I've nothing to back this up beyond it's nice to think so.
 
no no .. you are absolutely right.

from pump directly to the cpu block.. i.e the more restrictive
but i prefer to pass it from rad first.. afterall the block is far more restrictive than the rad.. consequently being the chocking point.

besides.. I was reading some automotive articles on drugster engine setups.. lol
and it is preffered the water pump to be adjacent to the radiator.
as a matter of a fact you can buy rads with attached waterpumps for drugsters...
a bit extreme I know but the theory behind is the same.. i.e. max flow and cooling.

nice thoughts on carrying power from the lian li..
but I am going to run crossfire soon.. (mobo is a dfi jr p45) with a corsair750w
so I would like to keep the psu strictly for the pc, and run pump/s lights fans from a second one.

and it is possible to fit a double slim rad in it.. but not mine.. cause it's crossover so it makes it longer.

have a look at http://www.million-dollar-pc.com/ it has been done allready.

but we are off topic

I CAN'T MAKE UP MY MIND
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

2xtriple RS
1x triple RX + a blue temp lcd + rakors
1x quad RX
:S ?????????????? :S
 
By adjacent, do you mean res -> pump -> radiators -> blocks to res? If it makes a difference, you're encouraging heat dissipation rather than heat pickup, which is probably the right way to go about things. Sure, worth the peace of mind.

I don't think you've understood me. I suggest moving the 120 out of the radbox and into the lian li, where it will fit no matter how long your gfx cards are. I agree a 240 wouldn't.
Now get a new 240 radiator and fit it into the space now available in your radbox, removing the psu to achieve this.

The corsair won't struggle. The pump is 30W (I think), so at the absolute most your box will be drawing about 45-50W. This is negligible, the psu just wont care. It also means your pump will turn on when your computer does automatically, which can't be bad. So this is the solution I vote for.

If what you really want to do is make a new enclosure, then I'm quite partial to the idea of a triple on front and back of a box, square from above but only just tall enough to fit the radiators. I'd like to stand my monitor on one of these.
 
no no.. I got you alright.. it is a good idea for a more efficient box.. but no.. i prefer an independent cooling unit.. with a separate on/off ans psu.

as about fitting the single rad in the lian li.. y not fit a double since it fits..
trust me I have thought of most possible scenarios.

at the end of the day.. I much prefer to make a new stand.. with 2 triple on view..
wooden sassy with plexy envelope and discreet lighting..

to be more precise.. I was considering to make the lian li an AMD HTPC...
and transfer what's inside onto an antec skeleton... with the custom stand I mentioned before.

unfortunately I am good making things.. but not drawing them.
I need a skeleton theme stand.. something that will blend and bond with it..
and I was considering a Mclaren paint theme.
that pearlish silver with bright orange and black.
which is the most difficult paint out there...

anyways.. will see... time and money will show..
right now I am working on an akasa server box.. and a coolermaster stacker(version1) case.
hopefully in a month or two they will be complete
 
So your outside temp is what 32°C? and you are gettin 60°C under load by just having a graphics card and cpu in a single loop?

Initially I'd say get rid of that Black ice and just add a 240RX and you should be fine.

But if you are going to build a new radbox anyway, get a 480 and get rid of everything else. And make sure you build the new radbox with expansion space for another 480 :)

What cpu and gfx are you running that they crash at 60°C? That shouldn't be happening anyway. CPU and gfx should both be able to handle 75-80°C without crashing your system.
 
I've always thought that one (best possable) rad per loop is best option.
Multiple rad = significant flow rate drop.

The drop can be reduced by only using RX or PA rads but generally quality IS better that quanity. Martin's liquid lab flow estimator will help you with various options and compairing multi rad loops.

pump--triple-cpu--double--gfx--triple--res-pump

I don't beleive this is a good idea - if you have the room for three rads have a duel loop with a single rad in each.
 
double loop mean 2 pumps..
unfortunately i destroyed my 2nd one..

now in relation to rad.. thermochill released its 120.4 for 75pounds.. with normal fan spacing but still on g3/8 threads.

the only problem is the weight (3kgs) which is another 25pounds postage.

the Rx480 costs only 10pounds to post.. but 85 to buy.
which makes me wonder.. is the RX so light? how can that be?

and by an interview with the XSPC owner which now is co-owner of thermochill stated that PA's matt paint performs better than the gloss which is thicker and the one being used by XSPC

so putting all these factors in.. i bet the PA is a crown performer ...
3kgs of copper and I think 1.5 litres of water.. :D

Perhaps we're hitting a language barrier here. Do you not directly contradict yourself in these two posts? Your 120 will fit, as it is not behind the gfx cards, so I would put it in the case rather than throw it out. You can't fit your double because it doesn't fit?


Thermochill are better than xspc, perhaps not by much but they are better. Have you considered feser? Similar design themes to thermochill, standard G1/4" threads. Their website plays music at you but actually offers 3D models of their radiators, the latter is amazing enough that I'm happy to be using feser.

Building a new rad box from scratch will be fun and probably the best answer here. One quad with space for a second seems likely to be all you could ever need. It doesn't quite fit your current theme, but have you thought of making an enclosure for just one quad and associated fans? Have it freestanding, probably upright, with barbs on the outside to connect tubing to? Then at a later data have a second, would look quite nice sitting on a desk
 
no no.. i got you ok the first time... and no I am not contradicting myself...

let me explain...
1.My double rad doesn't fit cause it is a crossover.. i.e. in from one side.. out from the other side.top/bottom if you like.. which makes it longer than the normal double ones.

2.fitting the single inside.. at the side where there are no video cards.. makes it kinda impossible.. cause:
a.you can't put it vertical.. (threads on top side) cause it hits on the 5.25 slots cage
unless if i cut it.. but I am currently using it for hard drives.
b.putting sideways... its gonna force me to put it on a push configuration.. which it wont work at all with the current fan. this rad has very dense fins.

3. as about feser... I find them to be a bit overpriced...

I emailed the shop I am planning on buying.. regarding the postage difference between the 2 quads.. and depending their answear I will act accordingly.

I think I am leaning towards a quad.. and yes it will go externally for now.
and having it on a nice stand sitting ontop of my desk, with some led fans... sounds quite nice to be honest...
..never thought about it before... good one mate!!!


--------------

this morning I managed to make a nice "X-mass basket" lets say..

which includes..:

1x Magicool extreme III
1x temp LCD
2x 3/8 rakors
1x UV dye
1x water anticorrosion
3x 1200rpm 14db fans

all for 95pounds.. :D
its either that..

or the quad.. and just the quad!!! :|

------------

tomorrow I will place the order.. I just hope I make the right one...

ps - feel free to tell me what you think.
