Two Radiator for the system

[M@deira]

Hi

I am thinking of mounting my new computer using two radiators, 2 x 120mm + 3 x 120mm connected in series, will be that I would have a better performance than just a radiator 3 x 120mm?

The model radiators are 2 x 120mm (MCR220 - QP) and the 3 x 120mm (MCR320 - QP)

Ps: Sorry for the bad ingles ..:(

ok what with all them rads are going to cool, hardware spec's. what will be the computer area temputure(room)

Here is the specification

GA-X38 DQ6 / Quad Q6600 G0 / 8800GT 512Mb / PSU 600W Sevemteam / 2gb Crucial Ballistix PC8000 / the temperature here in Brazil mainly at the time the temperature is 25 to 28 ° c.:eek:

If you have a Thermochill PA120.3, one is enough for all this.

It is that the cost of the two radiators will be cheaper that only a radiator PA120.3 of Thermochill.

And on the performance, I will be a better cooling radiators with the two mentioned above?

nice to hear another brazilian ;)
You should think about space issues too. With one PA120.3 you could have the same performance with less space and if you use just 3 fans you may consider less noise too.
Living in Brazil you should worry about shipping costs too, one PA is cheaper than 2 MCR to ship. Considering the costs of shipping and more fans needed for the other setup you will be even with a PA120.3.

Lesson 1:

Watercoolant, can never go below ambient temps.

So that means, the coolest you can run your coolant is room temp. So if 1 radiator can bring your coolant to that point, then adding another radiator, to another radiator wont do very much until you exceede the stress point, or load on that 1 radiator.

Lesson 2:
You calculate how much heat your system is going to be putting out. Whatever blocks your running is a source of heat. You add each component up with its respected heat number and get a final number.

Example:
Q6600 ~ 190-200W of heat overclocked @ 1.42+ Vcore
HD3870 ~ 105W <--- is that right??? someone said it was 105, and not one corrected him, so i assumed it was correct.
NorthBridge ~ 15-20W

Now Add 5W for your pump. Just being a bit generous.

The total i get is ~330W MAX.

Now you look up what can cool ~330W with fair ease. Oh i think the PA120.3 has a range of 500-600W.

So your using a 500-600W radiator to cool a 330W heat source...
Adding more radiators then would mean.... No your temps wont get much better. Maybe at most 1-3C each radiator you added on, but at the cost of the increased restriction, which isnt worth it.


I hope this makes sense... i tried to make it as easy as possible, and i skipped a bit of stuff, but i hope you get the general idea.

Hello Leo.

Então cara estava vendo a questão do custo, para mim fica mais barato os doi radiadores da Swiftech, sobre o espaço, comprei um gabinete Enlight de 7 baias, sendo assim espaço nao teria problemas... a questão é mesmo o desempenho na refrigeração.. sera q somente um PA120.3 da Themochill seria melhor.. que duvida,... =(

(Hello Leo.

Then face was seeing the issue of the cost to me is cheaper hurts the radiator of Swiftech, on the area, bought an office Enlight, 7 bays, and thus do not have space problems ... The question is the same performance in cooling .. Q will be only a PA120.3 of Themochill would be better .. That doubt, ... )

I understand, I think q in the best overview is even get a PA120.3 Thermochill, because as the ability it is very superior to the other 500 ~ 600W this great even more, only thing is that the cost would be a little higher for me but value is not all that matters is efficiently. :up:

well then get a MCR320.

The MCR320 has a range of somewhere near 400-450W with low/medium speed fans. Its a tad below the PA120.3.

Your not exceeding the 450W heat output so a MCR320 should do its job. However the PA120.3 will give you slightly better temps. Like 1-2C

Thank you for help, I am grateful for the explanation. The users really like to help the XS:yepp:

Hi, M@deira. You have space for 4x120 radiator?
Well I’ve DIY 4x120 radiator in progress. External dimension 138x524x60mm (WxHxT), yes is BIG:eek:
Core dimension 136x42x480mm with 2 row 18x2.3mm tubes, fin density 16 FPI.
I have material to make two radiators if you have interest in DIY radiator PM me.:)

Very nice... The core on that looks bigger then a TC.

Looks great, Lucas!:clap:

If you want I may test the performance of your RAD against the PA120.3

M@adeira: We cannot forget that the Rad graphs measure the Delta of 10º for the water and not for CPU. So, you can spect deltas over 20º for your Q6600 if you overclock it. I'm running my Q6600 and 8800GTS (700MHz core) with one PA120.3 and I'm getting a little less than 20º delta for the cores.

[Pudi]

I want one now :D

[septim]

dang 60cm or core, if you put side panels for rigidity, it be around 70cm or 3inch thick.....

[Xilikon]

70cm = 27.6 inches...

you mean 60-70mm ;)

PA120.3 + PA120.1 :D

Good idea, I send PM after finish it.:up:

Hi septim, core thickness is 42mm(1.65 inches) and 60mm(2.36i nches) with fans support.:rolleyes:

Very good this project, I have real interest, had an MP for you with my MSN to talk.

Thank's

[leo_bsb]

great news, Brazilians making something to the WC scene ;)

[micmic]

If you add a second radiator please post the difference in temps. There will certainly be an improvement, but I would like to know how much. I have a spare radiator that I'll install if the difference is substantial.

Off to listen to some Marisa Monte now :D

Heh, Brazil is tropical paradise and very hot country, very good for water cooling and big radiators.:D

[Pudi]

What about mass production lucas ?

[Boogerlad]

hey lucas, maybe you could make it single pass so then it isn't so restrictive.

[lucas-10]

May be, but need more time for tests and market research.;)

[lucas-10]

hey lucas, maybe you could make it single pass so then it isn't so restrictive.

I can do that but (I think) the gain in flow rate is about 5% for most commons WC rigs and loss about 20% in efficiency (with same flow rate and fan speeds)
Corrects me if is wrong comments.:)
