Two Radiators - Page 2

post #11 of 24
Thread Starter 
Many thanks for all of the replies, guys. One more question...would there really be any benefit to using two of these? I have yet to really experiment yet and I'm unsure of how much back pressure they create, but would there be a temp drop?

Also, would I be better off having T's and Y's in my line so that each block gets its own line?

Thanks in advance.

I suggested you just use 1 single 360 GTS before,what all are you going to put in this loop?...
Don't put any more fittings in your lines then you absolutely have to have...Each one you add restricts the flow....Plus if you started running individual lines to everything you would have to figure out a way to balance the flow going to each one...In other words some would get a lot of water and some would hardly get any....It would be a pain in the neck to do...

EDIT: I meant to say 240 GTS Rad

Yes, adding a 'T' to isolate your GPU from CPU will have lower temps......for one of the items, but not both.

i.e.-> Liquid in your system will only be cooled to whatever temp is currently possible with your setup, but by removing the 'daisy-chain' you are allowing both components to get *ambient temp water, rather than having it be heated by one component and then passed to the other.

I have a 'dual loop' system now, and am happy to say that I dropped my GPU temps 3-4c @ idle and gobbs more @ load.
*I cannot give a "real" number to the actual load temp drop, as I upgraded my whole WC system, when the 'T' was added. Before w/ both inline my gpu idled 4-5c above my CPU. Now they idle at the same temp.

Umm, nope. 'Closed systems' will always equalize pressure throughout the entire loop. If you add another pump, you do not double your flow rate at that particular point, but you might negate some of the loss put into your loop from your blocks and such.
*Look at exhaust systems for cars and race cars. True Dual exhaust systems come from the motor, straight back, to a 'CAT', from there, typically there is whats called an 'pressure equalizer'. This is no more than a pipe that connects the two lines together. Since the exhaust comes from seperate outputs on the engine, it is combined again later on before it exists the car, to equalize the back pressure in both of the exhaust lines.

Now, do to different compnents in each of the loops, you might have a small difference in the pressure between the two lines, but the flow rate should still be close to the same. You dont have to do any crazy science to balance the lines though....they do it themselves.

Oh yea, I kept looking at the 350, which is what I have..not the 355..

That was just a simple way of saying it...You have to take into account the restriction of each individual block which does restrict the flow...Plus he's talking about ram coolers and other things which would probably have diff sized tubing....For a new guy it's a real pain in the neck....

I really hope you aren't seriously considering watercooling your RAM and Chipset. The only items that should be cooled are the CPU and GPU(s).

You're looking at an eccentric and pointless amount of coolant/tubing/heat/potential leaks/waterblocks/ and overspending of money.

The most you should get is one CPU block, GPU block(s), pump, 1 radiator, and a res.

IMO.

RAM coolers...? Eeeeewwwww
Grossly ineffective if you ask me, unless you run 2.5+ er sumthing and cant use a fan. lol

I guess they look nice, but 'tha bling factor' doesnt out-weight the mess and restriction.

Exactly... I was trying to get him to just cool CPU and GPU and forget all the other pointless things that air cooling would do just fine on....

Here are some better prices on the pumps. The flow rate of the one you found will be more than sufficient.

Multiple radiators are not necessary. Go for 1 360mm radiator. The temperature of the water will not change significantly throughout the loop.

Cooling the NB with water is a worthwhile thing now. This is because in order to get the Core 2 to its maximum potential, you need more than 1.85V in the NB.
