Multiple Radiators?

post #1 of 8
Thread Starter 
New to watercooling, so if this is a lame-tard question, excuse my ignorance )

But wouldnt it be effective to use multiple radiators? For example pump -> 240mm radiator -> cpu -> 120mm radiator -> chipset -> gpu -> res -> pump ? Or would having the second radiator restrict flow too much to be worth it?

I was just thinking that the water will be hottest off the cpu, so why not cool it again before I pump it into my chipset/gpu?

A lot would depend on what pump you have...I wouldn't bother with WC'ing the NB, just get a good air one like this...Swiftech MCX159-CU Extreme Duty All-Copper Heatsink w/ 40mm Fan


If you have a good 240 rad it should be fine for CPU and GPU...If you are running SLI you might want to get a single 360....These are decent Rad's and not real expensive...Or just go with a heater-core if your on a budget...Danger Den :: Radiators :: Black Ice Series :: GTS Stealth Radiator :: Stealth GTS 240 Black Ice

i'm on the same ide
gonna be doing a 2x dual rad in my system shortly

the reason i want the second rad in the midle of the loop is couse the water cant be cooled more then room temp and cool gpu is always nice

2 radiators will cool the water more, but the flow will be restricted. If you're already cooling to a little over room temp you won't see a decrease in temps that matters.

yeah, for each thing you have in your loop you effectively decrease the flow so the gain is pretty much nill

I am brand new to water cooling as well. I have a custom case under construction that will have 2 radiators. In the top is a Thermochill PA120.3, with 3 Skythe S Flex 1200 rpm fans. On the back is a Thermochill PA120.2 with 2 of the same fans. The CPU, RAM and Nvidia chipset (Im running SLI) goes to the top radiator via a Swiftech MCP655 pump. The rear radiator will be for the dual 7950 512MB superclocked eVGA video cards and the HDD's, also with a swiftech pump. Both pumps outputs will be regulated.

Im hoping this setup will be both cool and quiet, and allow for some overclocking to boot.

Why does everyone insist on H20 for the HDD's.....it is soooo not needed. With the same breath, you guys are worried about restriction too? C'mon, they are freakin hard drives....my 10K Atlas SCSI's dont even get warm to the touch....you think a regular HDD will seriuosly get that warm...doubt it.

Your one PA120.3 would be more than enough to dissapate the kind of heat you are talking about putting though it..you just need some good airflow...no stealth fans, you need a good 50-100cfm / fan. That Rad is capable of dissapating over 500W of heat easy-> 2 is overkill for sure.

**im not trying to rain on your parade, I just hate to see people waste money for the sake of 'Not knowing better'.

My IDE Western digital 160 passes 110F when its churning full tilt.

Not everyone has cool HD's.
