How Far Can You Push A Single Loop?

[Cutless009]

Im thinking of putting 3 GTX285's and an i7 920 on a single loop with a swiffy MCR320 and a DDC 3.2 w/ 3/8" tubing. My goal is anything better than stock cooling while lowering noise levels.

Thoughts? possible? bad idea? I've always been an "overkill it just to make sure" kind of guy, I dont want to see horrible things happen now that Im trying to be reasonable lol.

I do intend to try and clock the i7 to at least 3, if not 3.5ghz, but Im not expecting a powerhouse overclocker out of this system, I just need a clean stable quiet system for a workstation.

most i920s can do 3.8ghz easy with hyperthreading on...

power drawn..660w - 80% efficiency----550w heat?????

i'm guesstimating cpu draw is 130w(its overclocked) and 420w from the gpu....

here is martins review of the mcr320

if you use push pull....martins graph would look totally different...martin only used either push or pull....

Wow, thanks man, thats some awesome info for me to research, thanks for the link!

On a side note, hank fails AGAIN:

FAILLLLLLLLLL

ouch thats 30$ each for tri-sli...

i'm still contemplating getting the 295 or ..the new 4890cf(april time)

triple 285s and a Core i7 on a single Swiftech MCR320?

I think you would best stick to stock air cooling with the free Intel heatsink and Nvidia video card coolers. I think you may get better temps that way.

Don't water cool for the sake of having a water cooled computer. I don't think a MCR320 is great for a Core i7 alone, let alone video cards.. and three of them.

You are saturating a MCR with anything more than 400 watts, and that's with super loud and powerful fans. Thermochill's limit is 500 watts.

Each videocard has a TDP of.. what?... 180w.. the Core i7 overclocked is a good 240W. You go figure that math.

According to Martin's testing, an MCR320 can take ~600W with only a 12.5C air to water delta with 1600RPM fans.

That's good enough to be competitive with great air cooling on the CPU and is much, much better than the stock GPU coolers. And quieter too.

With 3x 1000RPM fans the water to air delta is still sub 20C at a whopping 600w, which is by no means great, but definitely quieter than comparable aircooling on the CPU (and again, the GPUs don't compare because stock solutions lag very far behind WC). :)
