suggestions on dual loop or dry ice??? - Overclock.net

okay so if any of you have read my cpu overclocking problems with the new 6400+ BE then you will probably know what i should do....if not here is a link to the thread...

http://www.overclock.net/amd-cpus/35...overclock.html

so far i have been running pretty hot on a single loop for cooling an overclocked cpu and overclock northbridge...

now what it looks like is this...

dual rad/res->cpu block/pump(apogee drive)-> nb chipset block->rad/res

what i am thinking of doing is something like this:

1st dual rad/res->cpu block/pump(apogee drive)->2nd dual rad/res->2nd pump->nb chipset->1st dual rad/res

i think it might be overkill!! i could also do a single loop and have it this way

1st dual rad/res->cpu block/pump(apogee drive)->nb chipset->2nd dual rad/res->2nd pump->1st dual rad/res

any suggestions or comments would be very appreciated!!!

one more thing to add...is there some type of liquid coolant product that, with the system i have set up already with the single loop, could low my temperature better???

like dry ice coolant or a different type of liquid coolant...right now i am using the swiftech generic liquid...

u can always run straight distilled with some add-ins like pentosin...

i hope ur pumps are the same type and model cuz otherwise u'd be just making a hindrance to ur stronger pump... if u have two pumps, go for 2 separate loops... it helps keep temps down. always run the radiator before ur block... so rad before CPU block = good.... but rad after ur NB chipset? run it before ur NB chipset and it should help.

it looks like u got integrated block and pump and ur reservoir is built into your radiator or your not usin a reservoir... so u should have it : Radiator -> Cpublock/pump -> back to radiator for loop 1.

Loop 2 : Radiator/Reservoir -> Pump -> chipset -> back to radiator... this setup is an exception to the radiator before block because u do not ever want to starve ur pump from coolant.

if u want a single loop. it should go reservoir -> Pump -> 1st radiator -> cpu block ->(2nd pump if necessary/optional) -> 2nd radiator ->chipset block -> back to reservoir.

Save yourself some tubing and toss the pumps in serial. Putting them in two different parts of the loop will not save you anything.

Putting a radiator (even a single 120mm) between the two blocks will make a HUGE difference. Just the fact that you aren't pumping already hot water into a block is a good thing.

What you will want to do, is put the biggest radiator BEFORE the biggest heat source (the CPU), and if you go with a smaller second rad, put it before the lesser heat source (the NB). This ensures that the water is as close to ambient as it can get before going into the hottest block.

Depending on your pump, you may not even need a second, unless your blocks or rads have a huge pressure drop... but if you have the cash for the second pump, by all means, get it. A second pump never hurt anything, and is usually a good idea for those sad times when a pump may die.

well i think i solved my problem i can mount two more fans on the back of my mcr220 and have extra cooling on the rad that way it will be able to drop the heat alittle more...

but i don't think that i can get the fluid any cooler than room temperature 20C+ than to use some type of chemical and distilled water...i was just wondering if someone has a mixture that keeps it sub 20C idle that way i can have more stability...otherwise i might want to go with a dual loop and then maybe even add on the two video cards might be able to overall drop alot of temps....i might want to go with a triple rad or quad rad for that though....

i might just go with this....Swiftech MCW6500-T TEC and upgrade to a ultra+ kit....and see if that doesn't alleviate my problem...might even try phase change...
