Looking for advice on 6x120 radiator setup

post #1 of 8
Thread Starter 
Hi guys

This idea may sound utterly stupid...

I'm planning to water cool my next rig. The Lian Li PC-Z70 looks like a good idea with its side panels (I utterly hate to blow hot air into the case). Lets say I remove the 3.5" cage and mount 6x120mm radiators in its place (see attachment). This brings up a lot of questions.

First, let me clarify...
Looking at the case from the front, the air goes from left to right. So why would I use 6x120 instead of 2x360 or (a thicker) 1x360? The answer is lack of space for in and output, especially if I need to connect the sandwiched radiators or cut the bottom of the 5.25" cage. This is why I decided to get 6x120 radiators and make the in and outputs all face the rear of the case. Since this will be a future setup (once socket 2011 and nvidia 6XX series are out) lets assume it's a 1366 mobo with 2 GTX 580s.

And now the questions.
- how bad will the 6 radiators perform (I've read about sandwiched 360 rads and they work somewhat better than a single 360 with a nice push-pull setup)?
- single or dual loop?
- if dual, how many rads for the 2 GPUs?
- etc (once I get some answers)

A 240mm rad will cool GTX 580s in SLI. An i7 shouldn't need more than a good 360 (I have a Black Ice GTX 360 on mine with Ultra Kaze 2000RPM fans). I would go with a 360 and a 240. You are going to have a lot of tight bends and a lot of tube trying to connect 6 x 120mm rads.

There won't be any tight bends. Elbow fittings should do the job I was more concerned about performance. The rads need to be sideways and therefore won't have enough room for tubing (2.5+6+2.5+6+2.5=19.5cm pretty much fills that area - case width is 22cm), not to mention (as I said in my initial post) there won't be enough room (height-wise) for a 360 rad because the in/ouput would be in the 5.25" bay which is really hard to work with and needs some drilling. Although I'm a bit shocked at the i7. Does it really dissipate that much heat that two 580s need less cooling? If the new 2011 models will be anything like the i7s then I guess a single loop would suffice.

Thanks for your reply.

This thread is useful for comparing performance of sandwiched rads.

Yup, read that already.

you'd be better off getting a gtx 360 for the front and placing a thin 360 rad up top or another thick one on the back. Stacking that many rads will lead to horrendous diminishing returns and will end up being a waste of money. Probably perform worse than a gtx 360 as well.

So, you say I'd be better off getting another chassis coz those won't fit.
post #8 of 8
no, u can fit 2x 360 rads in there, you just have to be keen to do some dremmeling on the top panel
