WALLA!!!
nice rig u got there bro

well...in my opinion since i assume that u would want to oc ur rig...a dual loop would be better...

ur logic is acceptable but bear in mind...after OC-ing..the heat would all be different...i believe 45C is diff to yield as even most of the users here who is running i7 n is overclocking it have temps of 40+...thats malaysian weather for u...even i on a c2d(e8600) @ stock speed can reach 46 on load...

with what u said...the temp for i7 n the GPU's can reach up to 100C...so total them up ur rads have to dissipate up to 400C...honestly i suggest u get urself a dual loop...maybe 120x1 for CPU n 120x3 for ur GPU's...dat way each hardware sort of have its own single radiator...n i believe that would be better since heat transfer would be more difficult the higher the temp of the fluid...consider that a hot metal dipped in a bucket of ice water would cool faster than dipped in hot water even if its only a milisec diff...but take it to a computer level...the diff is quite big...

but still, if u dont want to OC i guess theres no harm done if ur running a single loop...

hi limhongwoon, i considered it but I am trying to keep my build under RM 15,000
right now i am a bit over and am actually considering scaling back.
price on the i7 980 is still high, and price on the 965 extreme has come down. i may even consider changing to a 920, since my supplier said the 965 is not in stock, plus the benefits of the 965 may not be worth the huge price differential, especially with the way Intel speed-binned the LGA 1366's - massive overclocks are easy.

what to do...

but a dual loop as you recommended would definitely make one loop much hotter than the other - i want the temp to be uniform across all chips. i would only consider a second loop if one chip had less tolerance for heat than the other, for example to LGA775's are not as tolerant compared to the GTX280 GPU, so having two loops was okay. but the high k-silicon i7's can run nearly as hot as the nvidia GPU's - so there's no advantage to isolating the loops.

but again, i will have to test it to make sure the system is adequate.

the more expensive option is to have two loops and a heat distribution block, but that is not necessary for my setup.

also it is not the absolute fastest build - plenty of hardcore enthusiasts with much more power than this. i actually set a budget for everything!

heya bro my suggestion, if you are still not getting a 975 ex, go grab 920 D0 is better since this cheap proc also can be Oc'ed as higher as 975 ex goes, this is called a golden batch can keep up a good performance as their extreme brothers too, you can save the money for something else either for better cooling solution, casing and gpus at once. Fermi is coming out soon and it will be better than current one, so if you ask me i will likely said it's not worth to over spend for a card such as GTX280 right now bro... it's just my nuisance opinion, you might think different.

anyway regarding your previous logic, i said a combustion engine is totally a different if you count that a vehicle is moving and the air will be push through the radiator hardly, while the computers only depends on small / considered still a low CFM fans compared to the air generated by a moving vehicle. The combustion engine is rated to running in a higher degree celcius while the computer chipset is rated at a lower degrees than the engine. So, it's a different league and cannot be compared... All the computer chipset consists of million transistors (electronically) while the combustion engine consist mostly based on hardware (non-electronically). That's why an electronic is more sensitive towards the temperature compared to others especially the chipset.

my 2 cents, way i see it u r not aiming for the extreme, more of a decent setup, considering some of your constraints and the mood ur aiming for, a single loop would be ok..but i'm curios to see how it'll handle summer temp though..it'll be better than SC thats for sure...not pretty sure on the pump and rad selection though
most guys here are extremely picky on even 1c hehehe well that include me...just stick to your first objectives or what u really want to get out of your system, so if its "better and effective than stock cool" so by all mean single loop might just be suffice, if it doesnt, than i hope u upgrade on those rads...if i'm not mistake koolance rad are aluminium so take heed bro...

Added on March 15, 2010, 5:49 pmthere u go, prety good advice there kino...


yup tru dat...mfg actually do freaking detail selection of the components/part of the loop, plus hundreads of hours on the bench test runing pedal-to-the-metal tests. we all just pick from the shelves whats within our constraints, preference, and he-says-she-says ... one loop might work, but selection of the parts and component in the loop is key..so for bang for buck, those swiftech's rad are pretty decent...

thanks kInOzAwA for your feedback - i think 920 with D0 stepping is a good idea, and i think you're right, all of this stuff will be outdated in a few years, so it's not worth spending the extra money. i am definitely considering it. i bet D0's are hard to find though?

also the logic for the GTX280 is that it is pretty cheap now - I think less than half of what it used to be. and all of the new "generation" of cards like the 275 285 295 are much more expensive with only marginal performance gains. I am sure I can wait a bit and find the next generation of graphics cards and CPU's, but id rather have a machine to use now.

perhaps a car engine logic is difficult to compare with electronics. but nobody has sufficiently explained the advantage of two loops. sure one loop may be cooler than another, but how much of an advantage is this? what's the net result? if someone can prove that there is some gain (performance, effective processor lifespan, etc.) i would be willing to listen.

Added on March 15, 2010, 7:09 pmvladtheimpaler - you have a good point and you are correct - not aiming for the extreme, just a good wc solution that outperforms air cooling. all koolance rads are copper core.

so i guess my next question is:

what temps are you guys getting in your loop(s) at maximum load? we can compare when done...



This post has been edited by CHiNO730: Mar 15 2010, 07:09 PM

yes, you're right joe... the swiftech rad always is a bang for bucks really... the flow is not high nor low.. its got medium flow

are you sure that the koolance rads are the cooper one bro? if i'm not mistaken they're build on aluminum, that's why it's seldom to see people using it when other parts consists of cooper made block inside (not outside).

for my setup, with no aircond and the ambient temp expected around 38 - 40++ degree celcius maximum load is around 7X+ degree celcius on a single loop (2 rads that's TFC 360 + TFC 240 - i didn't think it's overkill yet) to cool down the i7 proc (oc'ed to 4.4ghz) and 2 gpus that's on CF. that's why i'm planning to upgrade to dual loops. I need another pump and reservoir.. its voila then...

ok let me explain why we are need 2 loops instead of 1 loop setup.

On dual loops the temperature will be separate each other depends on the setup. 1 loop will cool down only a processor part. With overclocked i7 chipset, you may want that your proc clockspeed running higher as possible than high end air cooling, so we need better temperature.. it's not being an easy to maintain temperature on various setup that's contains cpu - gpus - mobo's fullblock, because each parts produce heat and when comes to proc & gpu especially dual gpus or triple gpus setup, it will generates a lot of heat via itself, so you cannot expect the result is better if you're using only one loop at the time. When you separate the loop each other you may find that the temperature will be better than using only a single loop. Another 1 loop will cool down the triple gpus + mobo's fullblock or maybe you can choose on which part you want to cool down more. If you're planning on overclocking the triple gpus more than your cpu will do, then you can choose bigger rad for 'em including the loop arrangement that contains mobo's fullblock on the weaker oc'ing side. hope you'll understand buddy

thanks for the feedback kInOzAwA,

so, if you keep the same radiator setup (TFC 360 + TFC 240) and do two loops, will your average temperature go down?

and yes, koolance rads are copper core:

Why u want to get koolance brand radiator ?? More cheaper ??

wahh they finally manage to get their head off their bunghole and change it to copper...was a huge debate on this awhile back, and not to mention the friction between them and HW labs
seriously though, if u didnt point it out i would never know ...but i think their exos series are still alu...

and the six million koolance dollar question is ........


yeah bro...why koolance's ?

This post has been edited by vladtheimpaler: Mar 16 2010, 12:31 PM

920 D0's are everywhere and easy to find =D
or why not go for 930 D0 ?

bro i think your temp is pretty good, different around 30c-35c from ambient, thats pretty good, whats vcore u r running bro ?
theoretically, with a dual loop, it should show some improvement...

my idle temp for cpu is around 46 degree up to 55 degree bro when my room become a sauna room.. hahhaha

930 D0 first batch didn't impressive as a golden batch of 920 D0, maybe need to wait until the next batch coming out...

you can see on my cpu-z for v-core bro, for the ram timing it's not valid anymore since previously i only using kingston value ram and still can run at 1600mhz but CL9..

good pricing with koolance - quality is still better w/swiftech, but honestly performance difference is not that much.
a copper core radiator is a simple unit IMO.

I'm sure you guys will disagree. =)

But you all have very nice and expensive setups, so I know you guys are giving good feedback. In fact I have changed my built to reflect. =)

spot "made in china" on casing.
FT02,simple but awesome

I'm so looking forward to ur update. Monster rig....

wah keep it up bro, after reading all these, i suddenly miss IANHO..

Update 3-24-10

Testing components - not final build.



Test fitting EK waterblock.

It makes a difference the moment you add in GPU/chipset block on the same loop. Water gets warm a lot faster thus impacting your temperature. It's still usable but if you want it to be better then something has to be done like adding up radiators or splitting the loop I'm telling from my personal experiences with water cooling over the years, not from reading reviews

aww 275 ? how much did it went for ? ...bro when are u gonna fit the 350 bro ? post some ict of it, if u can also the internals... pretty good block imo...
