Will dual 240 radiators be enough for i7 920 4GHz & three GTX 480s?

post #1 of 16
Thread Starter 
Hey everyone. So I actually have a couple questions besides the main.

1a. Will dual 240 radiators with 2k RPM fans be enough for an i7 920 at 4GHz & three (possibly OCing) GTX 480s?

1b. If not, will a 240 radiator + 280 radiator be enough?

1c. Ok fine, how about dual 240 rads and a 120 rad?

- The reason I'm asking about those setups is because I am looking at the Lian Li V1020 and those are the only internal radiator setups I am able to use. If anymore, I will have to look for another case.

2. Will this SLI connector work with these AquagraFX GTX 480 GPU Waterblocks?

3. Will an MCP355 be enough for three GPU blocks, one CPU block (with thick O rings), and how many ever radiators are needed for the above setup.

Any help is appreciated. I may have slow responses because it's late, but I'll be back tomorrow morning. Thanks!

Tough question really.

I think if you Push/Pulled fans on the rads you might get away with it.

I'd say no unless you have the rads mounted externally in cool ambients.

I had twin 240s with 8 fans (push/pull) with 2 ATI 4890 running 1GHZ core with a Q9550 running @ 4.25GHz and the water temp would get to 30'C thats with an externally mounted rad with 15'C ambients.

Seeing GTX480s give out alot of heat as well.

Same i would say your going to struggle with 2x240 rads,
it might be ok,
but i would go for different case eg a corsair 800d or a tj07 maybe.
Or could you mod the case you want to take more rads?

Edit- 2x240mm rads and a 120 might be good enough.

2x240's for the 480's and a 120 for the 920 will do it

I should have made a recommendation, to keep noise to a minimum I'd have a 1x360 with 1000rpm push and pull fans for the 480s and a single 120 will be sufficent for your i7 920.

1c. Dual 240's and a 120 seems like the best road to take. GTX 480's are renowned for being like portable frying pans and will put out a lot of heat, especially when overclocked.

2. The connectors should work provided that the spacing between the cards fits the size of the pipes. The spacing should not be a problem, though, as they will be designed to meet the standard spacing specifications of a water block when placed onto a graphics card in a standard motherboard.

3. An MCP355 will be fine however for two 240's and a 120 you are going to want two pumps in that loop to ensure a good flow rate. They don't have to be feeding each other, you could for example put a pump at the beginning of the loop then a pump in between the two radiators or before the GPU's.

If it was me, I would consider two loops and a different case. I would get a 360 or 480 radiator for the graphics card and a 240 for the CPU. You could use an MCP355 pump in each loop as well as an XSPC dual-pump bay reservoir to save some space. It'd also look a lot nicer as you could have two different tubing colours and the price won't be any different since you'll be buying pretty much the same value of components anyway. If anything, it may even work out cheaper.

I would get a better case for more elaborate WC. Maybe a TJ07 or an 800D? Something that can hold dual-360mm or dual-480mm radiators.

With that, I would get two Switech MCP355s.

Atleast 2x120 rad space for each GTX 480 if you plan on overclocking them

If you are set on a Lian Li case and who could blame you, I would get one of the full tower ones. I would also check out the Lian Li case forum and see what mods have been done to at least fit a 360 and 240.
