I want to cool an i7 and 2 GTX 480's what are my options? (NoL are you around?)

post #1 of 9
Thread Starter 
Guys,

I am still pretty much a noob - I just finished my first water-cooled build, but now I have caught the ""colder is better" bug. I suspect that phase-change cooling an overclocked i7 and the 2 heat monsters that are GTX 480's would be impractical. What about a water-chiller? What kinds of temperatures could I realistically expect? How much of a difference would sub-zero temps make on my overclocks?

I apologize for my noobness in advance!

Haha yesterday one friend said to another:

I was talking to my brother and I told him I had this friend who said noob all the time. My brother asked if he was a hardcore gamer...

Hey, I've got like 80 something Pm's to go through right now (I get like 30 something a day here and I spent the weekend slacking) so I'll hit yours up when I get there, but I can always post if you'd like. That's multitaskable

Sweet! No worries, I am sure you are popular - I just saw several posts that said you were not around much - perhaps those were older posts. I am not in a hurry, I want to do this RIGHT, so take your time!

Sounds good. I will say, larger the load, the better the chiller option is. If your not limited on space, a chiller can be placed rather far away with a beefy pump setup (like an iwaki rd20 or something). But the highest performance might be attained with a single stage on the CPU and water/air cooling on GPU's. I don't personally use phase on GPU's 24/7, only on my CPU's in some of my rigs. But chillers are quite a lot of fun and open up options for more end room and or future usability.

What would be the practical low temps for a water-chiller cooling the load I described? How much difference would these temps make from standard water-cooling (best guess). Basically I am wondering if the OC gains are worth it?

Depends on how big your willing to go. The easiest way would be to pickup a decent size window ac, cut and recover off the old gas, replace the compressor with something a bit beefier, add a receiver, sight glass, and new filter, TXV, and a large plate heat exchanger, and make it into a fairly large chiller. That will do your 700W I would say; or more, depending on the TXV used and orifice, and from the size of the compressor could figure out temps.

Like Nol said an AC is probably the best starting point. I skipped a few of the things he brought up (sight glass, TXV) mostly because I was ignorant and eager to get it done, and instead of a plate exchanger I used a coil/res setup.

However with a good thermostat I am getting 19-23C water temp like 17c lowest temp on the CPU. It could probably go lower but I don't want to fool with condensation so I stay pretty close to ambient, just a tad lower.

EDIT: I am running a single 9800gtx+ overclocked with a stock Q6600. Nowhere near your 700w, but you get the idea.
