Single Pump -> Two rads, will it work as well as i think?

[Spawne32]

Im designing a water cooling setup around my cooler master elite case the plan was to use 2 radiators and one pump for a CPU/GPU system on 3/8th's tubing. I made a quick drawing of the plan, just wanted to get some feedback as to what you think, and what kinda parts you think i should use for optimal cooling with out going too overboard in cost. I dont want to be spedning 5-600 dollars on cooling parts alone lol

wheres master epion *waits for smoke to appear*

Do you care about looks? because if you don't just throw a 120.2 somewhere and be done with it...

Yes i care about looks and i dont want alot of the stuff to be on the outside of the case, plus there isnt really anywhere inside the case to fit somthing that size.

[serialk11r]

Oh okay:D yay, i'm not the only one who's stubborn with looks:D I think that that would be totally okay, but a lot of people will tell you no... But I hope you know 2 120.1s costs quite a bit more than a 120.2.

[nn_step]

seems logical though the Rad that leads to the GPU is gonna be a little bit less effective though...

[flclisgreat]

for cheap and probably better than what your thinking why not just get good air cooling?

damn you nn, you keep posting right when i do

well ive had air cooling for some time and i really wanna do the water cooling this time dispite the price difference. Im still gona have at least 2 120mm fans in the case, low speed noctua fans probably, and a kama bay if i can fit it.

yes but better then going straight from the CPU to the GPU dont you think? I figured while im back there why not have the tubes run to a rad mounted to the 120mm exhaust fan, amirite?

Well the 2 rads i was planning on using were these...
Swiftech MCR Quiet Power Series radiators - 120mm Black $24.50

so not that too bad in price..

ya I got one of those. But they have welded on 3/8 barbs, so be prepared to do some modding or get adapters.

[flclisgreat]

well 3/6 tubing is gona hurt the performance and so is the one pump/2 rads. unless its a powerfull pump

is there a pump that you would recommend?

yes but im using 3/8's tubing :p

[Spawne32]

wheres epion when you need him :p

My goodness the crap people keep spewing!!

3/8" is fine. Route the tubing however is the easiest. It won't make a difference.

A DDC is fine. If you don't mind a little extra noise get a DDC+. It cost the same and has better flow, which might give you more peace of mind...though I doubt you'll see a difference in performance.

As for waterblock...a Fuzion or Apogee GT are safe bets.

Thanks! excellent info, im gona write this stuff down.

@Graystar

1. i never said how much it would hurt performance did i?
2. 3/8 will hurt performance, i would bet money on it(if i had any)less water flow=less heat taken away
3. routing it any other way than pump>rad>blank>blank, will hurt performance. the pump does output heat(however little it may be) if you run pump>block it will add the pump heat straight to whatever your trying to cool which defeats the purpose does it not?

[Graystar]

1. i never said how much it would hurt performance did i?
No you did not. However, it would be reasonable to presume that you believe the performance hit to be a noticeable amount.


2. 3/8 will hurt performance, i would bet money on it(if i had any)less water flow=less heat taken away
Well, if you bet money on it you would lose. The same amount of heat is always taken away regardless of the flow rate. Flow rate does influence at what temperature the transfer occurs. In the case of typical PC water-cooling setups, a flow rate of 0.75 GPM will usually bring you within a few tenths of a degree of your best potential cooling. Systems with 3/8” tubing have flow rates this high.

If you have a flow rate of 1 GPM for a 100-watt heat load, the temperature of the water varies by only 0.37 C. That is why the order doesn’t matter. The 0.07 C change in water temperature that an 18 watt pump makes isn’t going to affect CPU temperature in a noticeable way.

Yup, 0.75GPM going through a block will keep it within like 0.5C of any more flow. A DDC+ in a high restriction loop (multiple blocks, multiple rads) will get around that much I think. 3/8" tubing will cause enough restriction to, in a normal loop, raise temperatures by 0.1C:D

why not try it with just 1 120.2 rad like a thermochill and if the temps are unacceptable then chop another one in?

what is the hardware? A c2d not massively overvolted and a mid range(ish) gfx card will be fine on a 120.1 (I've done it with a 6800ultra and pentium D 8 series which were 2 of the hottest components money could buy! temps were high but workable and it stfu'd nicely)

If you're going to say something like an 8800gtx and a quad core then frankly you need to rethink your plans.

[serialk11r]

Try a PA160? No that would be too expensive I guess. Well why don't you say f*** that to the front drive bays and stick a 120.2 in?
