1200-1500 watt cooling advise

post #1 of 7
Thread Starter 
Hi,

I'm entirely new on water cooing.

I would nee to have an extreme rig with 4 high-end VGA cards and a single or double Xeon CPU. Total about 1200-1500 watts

What kind of rad could keep this monster cool?
A 9 fan mora can be enough?
Or I have to get two of those?

Any comment is welcome!
THX!

4 x 420mm Rads would be my absolute minimum.

I think a 1080 would do the job, more than enough.
Two would be what I would go for if I used 1080 rads, but I like overkill.

But the "how much rads I need" question depends on too many factors for anyone to give you a good answer.

- Level of OCing
- Room temps
-Tolerance for noise
- Case airflow design
- Fan spreed, push/pull, just push, or just pull.
- Desired delta T.

If you don't mind noise, only push performance during gaming with headphones, than a pair of 360 rads with 2000 rpm fans would be more than enough.

Additionally, external rads outperform case rads. But most don't want external rads.

And it also costs only $109 against ~$250+ of the multi-radiator configuration! I second the 1080 rad!biggrin.gif

Thx for the great answers!
External rad would be my choice!
I seen there are pretty crazy configs out there running 4 way sli or CF with 1 or 2 xeons, everything OC... like the "blue nightmare" config.
And these use to have 3 x 360 rads with 60mm depth.

Strange that sandwiching the rads with one fan between results worse coolong than a single rad.
http://martinsliquidlab.org/2012/06/08/hesmelaughs-radiator-sandwich-testing/
So, push-pull is way beter than another rad with the same amount of fans.

Unfortunately there are no fans with 280 or 360 mm diameter. A single large fan would perfom way better and more quiet in the same time.
I wonder if I would use 2 x 280 rad, one with the integrated pump+res, 5he other as normal. Could handle this amount of power with push-pull config at all?

In quiet mode I guess it could not.
So many of you have already built some serious configs, I don't really want to do researh myself.
The one thing for shure I would use is the external rad. No meaning to f*** around wit a case and optimising airflow as well!

Thank again for any requests!

A 1080 is 3x 120 wide by 3x 120 tall.
So you could use 4 x180 fans on each side.
But the fan screws would not match.
So you'd have to make your own fan backet for it.
I don't know how handy you are.
